B. Effective Date and Term. Company’s employment of Executive under this Agreement shall commence effective as of September 1, 2016 (the “Effective Date”), and continue until the Date of Termination (defined in Section 4(C)) (hereinafter such period of time from the commencement until termination of employment shall be referred to as the “Employment Term”).

C. Duties of Executive.

D. Duty of Loyalty. Except as set forth in Exhibit A, during the Employment Term Executive shall not, without the prior written consent of the Board, accept other employment and shall devote Executive’s full business time and attention and Executive’s best efforts to the faithful performance of Executive’s duties as an officer and employee of Company. Executive’s expenditure of reasonable amounts of time for teaching, personal business or consultation, or on behalf of charitable or professional organizations shall not be deemed a breach of this Agreement, provided such activities do not materially interfere with the performance of Executive’s duties and responsibilities hereunder.

E. Place of Performance. Executive’s principal place of employment during the Employment Term will be in Hamilton Bermuda. Executive will primarily provide services hereunder from Bermuda. Notwithstanding the foregoing, Executive understands and agrees that Executive’s presence may be required at other Company worksites, including but not limited to New York, NY, USA, or Executive may be required to travel for business, in each case, in accordance with Executive’s duties and responsibilities under this Agreement, as business needs require or may change over time and as reasonably requested by the Board.

2. COMPENSATION AND BENEFITS.

In consideration of the services to be rendered by Executive pursuant to this Agreement, as well as Executive’s covenants set forth in this Agreement, Company shall pay to Executive the following compensation, which shall be the entire and exclusive compensation for all of Executive’s services rendered and other obligations taken on Company’s behalf:

A. Annual Base Salary. During the Employment Term, Company shall pay to Executive an annualized base salary of $400,000.00 (the “Base Salary”), net of all legally required applicable taxes, withholdings, and deductions in accordance with applicable laws. For calendar years in which Executive is employed for less than the full year, the Base Salary shall be prorated and accrue on a per diem basis for only those days on which Executive was employed during such calendar year. The Base Salary will be paid by Company in equal installments according to Company’s customary payroll practices, but in any event not less frequently than monthly. Executive’s Base Salary shall be reviewed periodically by the Company’s Board or the Compensation Committee of the Board (the “Compensation Committee”) if so designated and may be appropriately increased from time to time in the sole discretion of Board or the Compensation Committee, as applicable, and may not be decreased. Company currently anticipates that the next review of Executive’s Base Salary will occur the earlier of or around July 31st, 2017 or the Initial Public Offering (“IPO”) of the Company.

Executive shall also receive as additional compensation $10,000 per calendar month (the “Housing Allowance”), net of all applicable taxes, withholdings, and deductions in order to assist Executive with his housing expenses. The Housing Allowance will be paid by Company in equal installments according to Company’s customary payroll practices, but in any event not less frequently than monthly.

B. Incentive Compensation. During the Employment Term, Executive shall be entitled to participate in all short-term and long-term incentive programs established by Company, at such levels as the Board or Compensation Committee determines in its sole discretion. The Executive’s annual short-term (cash) incentive opportunity target shall be a minimum of 30% of Executive’s annual base salary rate (the “Annual Bonus”). The actual amount of such annual incentive compensation shall be determined in accordance with the applicable plans based on achievement of Executive and Company performance objectives established in advance by the Board or the Compensation Committee. In order to earn and receive any such bonus, Executive must be employed by the Company, without having received from or tendered to the Company notice of an anticipated termination (for any reason), as of December 31st of the calendar year with respect to which such bonus to be paid to Executive is earned. Each such bonus will be paid no later than March 15th of the calendar year following the calendar year in which the applicable services were performed. Payment of an Annual Bonus for any year or other period of time will not give rise to an entitlement or expectation of an Annual Bonus for any other year or other period of time. Company currently anticipates that the next review of Executive’s short-term incentive will occur the earlier of or around July 31st, 2017 or the Initial Public Offering (“IPO”) of the Company but any incentive compensation, extraordinary bonus, may be administered at any time upon the Board’s recommendation.

C. Equity Compensation & Additional Discretionary Bonus.

(i) Upon the terms and conditions set forth in the following subsections, Company, as stated herein and in accordance with the below, shall grant to Executive shares of the Company’s common stock (the “Stock Award”) pursuant to and in accordance with the terms and conditions of a stock incentive plan being developed by the Company.

2

(ii) As soon as administratively possible following the adoption of the Company’s stock incentive plan by the Company’s Board, the Board shall grant to Executive the Stock Award. Subject to Executive’s continued employment with the Company, the Stock Award shall become vested and non-forfeitable over a period of time, referred to as a vesting schedule. The Stock Award will be subject to repurchase rights, change of control provisions, and other terms, each of which will be determined by the Board at the time of grant and set forth in the applicable Stock Award agreement that will be provided to Executive. The Parties agree that in the event that Executive is terminated without Cause (as defined below) or resigns for Good Reasons (as defined below) in connection with a Change in Control (as defined below), all the Stock Award will be accelerated and become vested effective on the effective date of the Change in Control. As the Company has not yet adopted its stock incentive plan, no specific Stock Award details are included in this agreement.

(2) Additional Discretionary Bonus: In addition to any other bonus under this Section 2, at such times as the Company may in its sole discretion deem appropriate, Executive may be eligible to receive a further discretionary bonus payment. The timing and amount, if any, of any such bonus shall be determined in the sole discretion of the Company. Such bonus, if any, will be paid in the calendar year following the year in which the applicable services were performed, in accordance with the Company’s bonus payment practices in effect from time to time for similarly-situated senior executives of the Company, including tax withholdings, but in no event will be paid after March 15 of the year following the year in which Executive’s right to such amount became vested. In order to earn and receive any such bonus, Executive must be employed by the Company, without having received from or tendered to the Company notice of an anticipated termination (for any reason), as of December 31st of the calendar year with respect to which such bonus to be paid to Executive is earned. Payment of a bonus for any year or other period of time will not give rise to an entitlement or expectation of a bonus for any other year or other period of time.

B. Acknowledgements. Executive acknowledges and agrees that: (1) Executive’s position with Company is one of high trust and confidence, (2) the Confidential Information constitutes a valuable, special and unique asset which Company uses to obtain a competitive advantage over its competitors, (3) Executive’s protection of such Confidential Information against unauthorized use or disclosure is critically important to Company in maintaining its competitive advantage, (4) all Confidential Information is the property of the Company Group, and (5) Executive shall acquire no right, title or interest in, to or under any such Confidential Information.

Executive promises to take all reasonable precautions to prevent the inadvertent or accidental disclosure or misuse of any Confidential Information. In the event Executive receives a request to disclose all or any part of the Confidential Information under the terms of a subpoena or order issued by a court or governmental body, Executive promises, to the extent permissible by law, to (a) notify Company immediately of the existence, terms and circumstances surrounding such request, (b) consult with Company on the advisability of taking legally available steps to resist or narrow such request, (c) if disclosure is required, furnish only such portion of the Confidential Information as Executive is legally compelled to disclose; and (d) exercise Executive’s best efforts to obtain an order or other reliable assurance that confidential treatment will be accorded to the disclosed Confidential Information.

11

Notwithstanding the foregoing, nothing in this Agreement shall be construed as, or shall interfere with, abridge, limit, restrain, or restrict Executive’s (or his attorney’s) right, without prior authorization from or notification to the Company Group: (i) to communicate with any federal, state, or local government agency charged with the enforcement and/or investigation of claims of discrimination, harassment, retaliation, improper wage payments, or any other unlawful employment practices under federal, state, or local law, or to file a charge, claim, or complaint with, or participate in or cooperate with any investigation or proceeding conducted by, any such agency; (ii) to report possible violations of federal, state, or local law or regulation to any government agency or entity, including but not limited, to the extent applicable, to the U.S. Department of Labor, the Department of Justice, the Securities and Exchange Commission (the “SEC”), the Congress, and/or any agency Inspector General, or make other disclosures that are protected under the whistleblower provisions of federal, state, or local law or regulation; or (iii) to communicate directly with, respond to any inquiry from, or provide testimony before, to the extent applicable, the SEC, the Financial Industry Regulatory Authority, any other self-regulatory organization, or any other federal, state, or local regulatory authority, regarding this Agreement or its underlying facts or circumstances.

In addition, Executive shall not be held criminally or civilly liable under any federal or state trade secret law for the disclosure of a trade secret that: (A) is made (i) in confidence to a federal, state, or local government official, either directly or indirectly, or to an attorney and (ii) solely for the purpose of reporting or investigating a suspected violation of law; or (B) is made in a complaint or other document filed in a lawsuit or other proceeding, if such filing is made under seal. Further, in the event that Executive files a lawsuit for retaliation by the Company Group for reporting a suspected violation of law, Executive may disclose the trade secret to his attorney and use the trade secret information in the court proceeding, if Executive: (A) files any document containing the trade secret under seal; and (B) does not disclose the trade secret, except pursuant to court order.

7. NONCOMPETITION.

A. Restricted Period. As used in this Agreement, the term “Restricted Period” means throughout the Employment Term and continuing until the end of the six-month period following the date on which Executive’s employment with Company is terminated for any reason (whether voluntary or involuntary). The Restricted Period will be reduced by one day for every day, during which, at the Company’s direction the Executive has been excluded from the Company’s premises and has not carried out any duties pursuant to the garden leave provisions of this Agreement.

B. Prohibition on Competition. Executive hereby covenants and agrees that, until the expiration of the Restricted Period, except for any activity identified on Exhibit A, Executive will not serve as an officer, director, employee, independent contractor, consultant or agent of, or have any ownership interest in, any business entity which engages in any activities anywhere in Bermuda or the United States of America that are materially similar to or competitive with the Company Group’s pharmaceutical development and Commercialization (as defined below) activities in the fields of (i) peptide vaccines for the treatment of cancer, and/or (ii) such other products which the Company Group is actively and demonstrably developing and/or Commercializing at the time Executive’s employment is terminated which such service, ownership or employment would involve Executive engaging in activities that are competitive with the Company. If a court of competent jurisdiction finds this non-competition provision invalid or unenforceable due to unreasonableness in time, geographic scope, or scope of the Company Group’s business, then Executive agrees that such court shall interpret and enforce this provision to the maximum extent that such court deems reasonable. For purposes of this Agreement, “Commercialize” or “Commercialization” means the sales and marketing phase with regard to a specific drug candidate in a specific country or region following the regulatory approval of said drug candidate in the applicable country or region.

12

C. Exceptions. Executive’s ownership of less than 5% of the stock of a company that is competitive with the activities of the Company Group as described in Section 7(B) and listed on a national securities exchange shall not be deemed to violate the prohibitions of Section 7(B). Also, Executive shall not be considered to have violated Section 7(B) with respect to the purchasing entity if there is a sale and Executive becomes an employee, officer, director or shareholder of the purchasing entity.

8. NONSOLICITATION.

A. Of Employees. Until the expiration of the Restricted Period, Executive shall not, directly or indirectly, either on Executive’s own account or for any other person or entity: (a) employ, solicit, induce, advise, or otherwise convince, interfere with the Company Group’s employment of, or offer employment to, any senior employee (meaning an employee with a rank equal or similar to Assistant Vice President) of the Company Group with whom the Executive had material dealings; (b) employ or otherwise interfere with the Company Group’s engagement with, or offer employment to, any consultant of Company with whom the Executive had material dealings; or (c) induce or attempt to induce any such employee or consultant to breach their employment agreement or relationship or consulting agreement or relationship with the Company Group; provided, however, that Executive shall not be in breach of this provision if any such employee or consultant, without inducement or solicitation by Executive, applies for employment at Executive’s subsequent employer in response to a general advertisement soliciting employment.

B. Of Clients. Until the expiration of the Restricted Period, Executive shall not, directly or indirectly, either on Executive’s own account or for any other person or entity (i) solicit, invite, induce, cause, or encourage to alter or terminate his, her, or its business relationship with the Company Group, any client, customer, supplier, vendor, licensee, licensor, or other person or entity that, at any time during Executive’s employment with the Company Group, had a business relationship with the Company Group, or any person or entity whose business the Company Group was soliciting or attempting to solicit at the time of Executive’s termination, (a) for whom Executive performed services or with whom Executive had contact during his employment with the Company, or whose business Executive was soliciting or attempting to solicit at the time of Executive’s termination, and (b) with whom Executive did not have a business relationship prior to his employment with the Company Group; (ii) solicit, entice, attempt to solicit or entice, or accept business from any such client, customer, supplier, vendor, licensee, licensor, person, or entity; or (iii) interfere or attempt to interfere with any aspect of the business relationship between the Company Group and any such client, customer, supplier, vendor, licensee, licensor, person, or entity.

For purposes of and as it is referenced in this Section 8 of the Agreement only, Executive’s period of employment with the Company shall be deemed to encompass any period, including before the Employment Term, during which Executive is or was an employee, consultant, independent contractor, officer and/or director of the Company Group.

9. REASONABLENESS OF RESTRICTIONS; REMEDIES. Executive has carefully read and considered the restrictive covenants set forth in Sections 6-8 hereof, and understands Executive’s obligations thereunder, the limitations such obligations will impose upon Executive after termination of Executive’s employment with Company, and that the Restricted Period extends for 6 months following the termination of Executive’s employment. Executive has had full opportunity to review this Agreement

with an attorney of his choosing, and Company has hereby advised him to do so, specifically Sections 6-8, before executing the Agreement. Executive agrees that, as a result of Executive’s position with Company, the length of the Restricted Period and each restriction set forth in Sections 6-8 herein are (1) fair and reasonable, (2) reasonably required for the protection of the legitimate business interests and

13

goodwill established by Company, (3) fair and reasonable in that Company’s agreement to employ Executive, and a portion of the compensation to be paid to Executive hereunder, are in consideration for such covenants and Executive’s continued compliance therewith, and constitute adequate and sufficient consideration for such covenants, and (4) not overly broad or unduly burdensome to Executive, either in geographic or temporal scope. Executive acknowledges that Executive’s compliance with Executive’s obligations and restrictive covenants set forth in this Agreement is necessary to protect the business and goodwill of Company. Executive agrees that Executive’s breach of Executive’s obligations and/or restrictive covenants under this Agreement may irreparably and continually damage Company, for which money damages may not be adequate. Consequently, Executive agrees that in the event that Executive breaches or threatens to breach any of the obligations and/or restrictive covenants contained herein, Company shall be entitled to: (a) seek injunctive relief to prevent or halt Executive from breaching this Agreement; and (b) money damages as determined by a court of competent jurisdiction. Executive hereby agrees that injunctive relief may be granted by a court of competent jurisdiction without the necessity of Company to post bond, or if required to post bond, Executive agrees that the lowest amount permitted shall be adequate. Nothing in this Agreement shall be construed to prohibit Company from pursuing any other remedy available or from seeking to enforce any restrictive covenants to a lesser extent than set forth herein. The Parties agree that all remedies shall be cumulative. Each party is responsible for its own costs and expenses, including attorneys’ fees.

10. NO PRIOR RESTRICTIONS. Executive hereby represents and warrants to Company that the execution, delivery, and performance by Executive of Executive’s duties under this Agreement do not violate any provision of any agreement or restrictive covenant which Executive has with any former employer or any other entity. Executive further agrees to honor and inform Company of any and all post-employment obligations Executive has to any former employer or any other entity with which Executive has or had a business relationship.

11. NOTICES. Any notice or communication required or permitted to be given hereunder may be delivered by hand, deposited with an overnight courier, sent by confirmed email, confirmed facsimile, or mailed by registered or certified mail, return receipt requested, postage prepaid, in the case of Company, addressed to Company’s principal office marked attention to the Chairman of the Board, and in the case of Executive, addressed to Executive’s personal address as appearing in Company’s payroll records, and in each case to such other mail address, email address, or facsimile number as may hereafter be furnished in writing by either Party to the other Party. Such notice will be deemed to have been given as of the date it is hand delivered, emailed, faxed or three days after deposit in the U.S. Mail.

12. LIKENESS. Executive hereby grants to Company a license to use, without further compensation or approval from Executive, Executive’s name, image, portrait, voice, likeness and all other rights of publicity, or any derivative or modification thereto that Company may create, in any and all mediums, now known or hereafter developed, provided that such use is in relation to Company’s business and consistent with professional business standards, and does not disparage or denigrate Executive. Within 30 days after the termination of Executive’s employment, the Company shall cease using Executive’s likeness.

13. INDEMNIFICATION; LIABILITY INSURANCE. Company shall indemnify and hold Executive harmless to the fullest extent permitted by applicable law in effect at the time this provision is implicated against and in respect of any and all actions, suits, proceedings, claims, demands, judgments, costs, expenses (including advancement of reasonable attorneys’ fees), losses, and damages resulting from Executive’s performance, within the scope of his employment, of Executive’s duties and obligations with Company. The Company agrees to maintain insurance policies generally for the benefit of officers and directors of Company and Executive will be entitled to be covered thereunder, both during and, while potential liability exists, by and pursuant to the terms of any such policy against all costs, charges and

14

expenses incurred in connection with any action, suit or proceeding to which Executive may be made a party by reason of being an officer or director of Company in the same amount and to the same extent as Company covers its other officers and directors. These obligations shall survive the termination of Executive’s employment with Company. Notwithstanding anything else in this provision, to be indemnified, Executive’s actions must not be intentionally wrongful acts, intentionally unlawful acts and/or acts of gross negligence.

14. GENERAL PROVISIONS.

A. Successors and Assigns. The rights and obligations under Sections 5, 6, 7 and 8 of this Agreement shall survive the termination of Executive’s services to Company in any capacity and shall inure to the benefit and shall be binding upon Executive’s heirs and personal representatives.

Company shall require any successor (whether direct or indirect, by purchase, merger, consolidation, reorganisation or otherwise) to all or substantially all of the business or assets of Company, within 15 days of such succession, expressly to assume and agree to perform this Agreement in the same manner and to the same extent as Company would be required to perform if no such succession had taken place and Executive acknowledges that in such event the obligations of Executive hereunder will continue to apply in favor of the successor.

B. Survival of Certain Terms.

H. Assistance in Litigation. Executive shall reasonably cooperate with the Company Group in the defense or prosecution of any claims or actions now in existence or that may be brought in the future against or on behalf of the Company Group that relate to events or occurrences that transpired while Executive was employed by Company.
