        This Employment Agreement (this “Agreement”) is effective as of June 1, 2019 (the “Effective
            Date”) by and between Greg Conn (“Executive”) and PDS Biotechnology Corporation, a Delaware corporation (the “Company”) and supersedes any prior
          employment-related agreement or agreements between the Company and Executive. Unless the context otherwise requires, all references to a designated section refers to the designated provision of this Agreement.

        

        

        Statement of Agreement:

        

        

        FOR AND IN CONSIDERATION of the mutual promises and covenants set forth herein, each of the Company and Executive hereby agrees to the employment of Executive on the
          following terms and conditions and, except to the extent specifically superseded by this Agreement, subject to all of the Company’s policies and procedures regarding its employees:

                POSITION

              


        

        

        Pursuant to the terms and conditions of this Agreement, Executive will be employed as the Company’s Chief Scientific Officer reporting to the
          Company’s Chief Executive Officer.  Executive agrees to devote all of Executive’s working time, attention and energies to the Company and while Executive remains employed, not engage in any other business
          activity that is in conflict with Executive’s duties and obligations to the Company. Executive agrees that Executive will not be employed by, or provide services to, any other person or entity without the prior written consent of the Company’s
          Board of Directors (the “Board”).

        

        

        Executive’s employment under the terms of this Agreement commenced on the Effective Date.

                COMPENSATION

              


        

        

        	
                A.

              	
                Base Salary

              


        

        

        Executive’s base salary will be $290,000 per year (the “Base Salary”). The Board will, within every six
          (6) month period, review Executive’s salary and options grants, as described in Section C below, and future increases in compensation, if any, will be made by the Board in its sole and absolute discretion.  At the beginning of every calendar year executive and CEO will agree on the number of months to be spent by the Executive at PDS and salary adjusted accordingly. A minimum of 9 months a year, including
            vacation will be spent at PDS.

                Performance-Based Annual Bonus.

              


        

        

        Executive shall be entitled to an annual performance-based cash incentive bonus (the “Bonus”) in an amount up to 30 percent of the Base Salary
          (the “Long Term Incentive Pay”). The Bonus shall be earned and paid in accordance with the Company’s
          performance-based incentive compensation plan (the “Incentive Plan”). After the completion of each applicable performance year, the
          Board or, if so directed, the Compensation Committee shall review the achievement of any performance goals by Executive and determine the amount of the Long-Term Incentive Pay earned by Executive based upon Executive’s
          achievement of certain performance goals and the amount of time Executive has spent physically located at the chief executive office of the Company. The Long-Term Incentive Pay shall be payable provided that the Long-Term Incentive Pay shall be
          paid by a date no later than a date that allows Executive to defer such payment into a non-qualified deferred compensation arrangement if Executive so elects.

                Equity Awards

              


        

        

        Stock Options. Subject to approval by the Board, on a date determined by the board, Executive may be granted an
          option (the “Option”) to purchase that number of shares of Company common stock determined by
          dividing (i) dollar value of options by (ii) the fair value of Option or the per share Black-Scholes value of the Option, determined as of the date of grant based upon the closing
          trading price per share of the Company’s common stock as of the date of grant, or the share price based on a recent equity raise, and such other variables as determined by the Company that are consistent
          with the Company’s financial reporting. The Option shall vest and become exercisable as determined by the Board, subject to Executive’s continuous service to the
          Company through the applicable vesting date. The Option shall otherwise be subject to the terms of the plan pursuant to which it is granted and/or an option agreement to be entered into between Executive and the Company. As previously approved by
          the board, you will be granted the option to purchase 40,000 shares of PDS Biotechnology’s common stock under the PDS Biotechnology stock option plan. The terms of this grant shall be subject to and governed by PDS Biotechnology’s stock plan and
          a stock option agreement between you and PDS Biotechnology. The exercise price of the options will be at fair market value on the date of grant which will be your first day of employment.

        

        

        Restricted Stock Units. Subject to approval by the Board, on the date determined in accordance with the Company’s established policy Executive may be granted an award of that number of restricted stock units (the “RSUs”) with a vesting schedule determined by the Company’s board of directors.

        

        

        Performance Restricted Stock Units. Subject to approval by the Board, on the date determined in accordance with
          the Company’s established policy Executive may be granted an award of that number of restricted stock units (the “Performance RSUs”) with a vesting schedule determined the Company’s board of directors.

                Benefits

              


        

        

        As a Company employee, Executive will accrue time off under the Company’s vacation program or any Paid Time Off (PTO) program that is or will be
          instituted.

        

        

        Executive will be eligible to participate in the Company’s employee benefit plans (including medical, dental, vision and 401(k) plans), subject
          to eligibility requirements and the requirements of such plans. Company reserves the right to modify or terminate benefits from time to time as it deems necessary or appropriate.

                Cause; Termination by Executive Without Good Reason

              


        

        

        In the event Executive’s employment is terminated (i) by the Company for Cause (as defined below) or (ii) by the Executive without Good Reason
          (as defined below), the Company shall, at such times as provided in this Agreement, pay Executive all earned, but unpaid amounts of the Base Salary, if any, to which the Executive was entitled as of the date of such termination and any Bonus
          earned for a calendar year ended on or before the date of such termination. In addition, the Company shall, within thirty (30) days of the date of such termination, pay to Executive or his estate in a lump sum all other amounts owed to Executive,
          and reimburse Executive for all reasonable and documented expenses so long as Executive has followed the reimbursement procedures set forth by the Company.

                Delay of Certain Termination Payments.

              


        

        

        If Executive is a Specified Employee at the Termination Date, payments of benefits under this Agreement with respect to a Termination Date that constitute Deferred Compensation may
          not be paid before the date that is six months after the Date of Termination to the extent required under Treas. Reg. §1.409A-3(i)(2) or, if earlier, the date of death of Executive. At the end of the
          six-month period described in the preceding sentence, amounts that could not be paid by reason of the limitation in this Section 3.4 shall be paid on the first day of the seventh month following the Termination Date. For purposes of this
          Agreement, (i) the term “Specified Employee” shall be defined in accordance with Treas. Reg. §1.409A-1(i)


          (which generally applies only when the stock of the Company is publicly traded) and such rules as may be established by the Board or its delegate from time to time, and (ii) the Termination Date will in all events be the date on which occurs the
          Executive’s “separation from service” as that term is defined in Treas. Reg. §1.409A-1(h).

                Acknowledgements

                B.

              	
                Restrictive Covenants

              


        

        

        Without the prior written consent of the Company, Executive shall not, directly or indirectly:

        

        

        (a) No Unauthorized Competing Concern. (1) During the term of Executive’s employment,
          either alone or as a member of a partnership or association, or as an officer, director, advisor, consultant, agent; or employee of any other organization, be engaged in or concerned with any other duties or pursuits requiring Executive’s active personal services that will conflict with Executive’s ability or objectivity in performing Executive’s obligations under this
          Agreement; and (2) for a period of 6 months thereafter, either alone or in any such capacity be engaged in, or concerned with duties or pursuits requiring Executive’s active personal services in the operation

          Executive to believe that the person offering the opportunity expects it to be offered to the Company; or (2) which Executive knows is closely related to a business in which the Company is engaged or expected to engage;

        

        

        (d) No Unauthorized Disclosure. During the term of Executive’s employment and thereafter, make or cause
          to be made any unauthorized disclosure or other use of any confidential information regarding the Company or any of its activities and operations, except to the extent reasonably necessary or appropriate in connection with the performance by

          information known generally to the public (other than as a result of disclosure by Executive in violation of this Section.

          on Executive’s own account or for any other Person (including, without limitation, through any existing or future Affiliate or any other Person with whom Executive is associated in any of the capacities
          described in Section III(B)(1) above), directly or indirectly without the express prior written or electronic consent of the Board:

        

        

        	 	
                a.

              	
                solicit or recruit the employment or services of any person, whether as an employee, officer, director, agent, consultant or independent contractor, who is, or was within 12 months preceding the date of solicitation or hiring (as
                  applicable), an employee or service provider of the Company, or knowingly induce or knowingly attempt to induce any such employee or service provider to terminate his or her employment or service, as applicable, or breach his or her
                  employment or service agreement, as applicable, if any, with the Company; or

              


        

        

        	 	
                b.

          capacities described in Section III(B)(1) above), directly or indirectly solicit, cause in any way, or knowingly encourage any Covered Customer (defined below) or Covered Vendor (defined below) to cease doing business in whole or in part or to
          reduce or divert or otherwise interfere with or impair his, her or its business relationship with the Company with respect to the Business.

        

        

        
          
            


        

        (g) Agreement Not to Disparage

        

        

        Executive agrees that, during the Applicable Period, Executive will not, in any such case directly or indirectly, disparage any member of the Company Group, including any owner,
          stockholder, director, officer, employee, partner, member, consultant, advisor, contractor or agent of any member of the Company Group, in any way that could adversely affect the goodwill, reputation or business relationships of the Company Group
          with the public generally, or with any of their contacts in connection with the Business. The Company agrees that, during the Applicable Period, the Company will not, in any such case directly or indirectly, disparage Executive in any way that
          could adversely affect the reputation of the Executive.

        

        

        	
                C.

              	
                Injunctive Relief

              


        

        

        Executive acknowledges that Executive has carefully read and considered all the terms and conditions of this Agreement, including the restraints imposed upon Executive pursuant to
          Section III hereof. Executive agrees that each of the restraints contained herein are necessary for the protection of the goodwill, confidential information of the Company and other legitimate interests of the Company Group; that each and every
          one of these restraints is reasonable in respect to subject matter, length of time and geographic area; and that these restraints, individually or in the aggregate, will not prevent Executive from obtaining other suitable employment during the
          period in which Executive is bound by such restraints. Executive further acknowledges that, were Executive to breach any of the covenants contained in Section III hereof, the damage to the Company Group would be irreparable. Executive therefore
          agrees that the Company Group, in addition to any other remedies available to them, shall be entitled to seek and obtain injunctive relief against any breach or threatened breach by Executive of any of said covenants, without having to post bond.
          Executive further agrees that Executive shall not plead adequacy of any relief at law available to the Company or its successors or assigns (as applicable) (including monetary damages) as a defense to any petition, claim or motion for preliminary
          or final injunctive relief to enforce any provision of this Agreement. Executive and the Company agree that it is their intention that all of the restraints imposed under the Agreement hereof be enforced in accordance with their terms to the
          maximum extent possible under applicable law. Executive and the Company further agree that, in the event that any provision hereof shall be determined by any court of competent jurisdiction to be unenforceable for any reason (including, but not
          limited to, by reason of its being extended over too great a time, too large a geographic area or too great a range of activities), such provision shall be deemed to be modified, a new enforceable term shall be deemed to be provided, or such
          court shall reform such provision, such that the intent of Executive and the Company in agreeing to the provisions of this Agreement will not be impaired and the provision will be enforceable to the maximum extent permitted by applicable law. In
          the event of any dispute or controversy arising out of or relating to or seeking to enforce this Agreement, the prevailing party in such action shall be entitled to recover from the other party all reasonable costs and expenses of the action,
          including reasonable attorneys’ fees and reasonable costs incurred in bringing and prosecuting or defending such action and/or enforcing any judgment, order, ruling or award granted therein, all of which shall
          be deemed to have accrued on the commencement of such action and shall be paid whether or not such action is prosecuted to a decision.

        

        

        	
                D.

              	
                Conflicting Agreements

              


        

        

        Executive hereby represents and warrants that the execution of this Agreement and the performance of Executive’s obligations hereunder will not
          breach or be in conflict with any other agreement to which Executive is a party or is bound (including without limitation any noncompetition obligations in any agreement between Executive and the Company restricting Executive’s activities after the termination of such Company employment), and that Executive is not subject to any covenants against competition or similar restrictions or any court order or other legal obligation or limitation that
          would affect the performance of Executive’s duties hereunder.

        

        

        	
                E.

              	
                Separate Covenants.

              


        

        

        The parties expressly agree that the character, duration and geographical scope of this Agreement are reasonable in light of the circumstances as they exist on the date upon which
          this Agreement has been executed. However, should a determination nonetheless be made by a court of competent jurisdiction at a later date that the character, duration or geographical scope of this Agreement is unreasonable in light of the
          circumstances as they then exist, then it is the intention and the agreement of the parties hereto that this Agreement shall be construed by the court in such a manner as to impose only those restrictions on Executive’s
          conduct that may be enforceable under applicable law, to the fullest extent of such enforceability to assure the Company Group of the intended benefit of this Agreement. If, in any judicial proceeding, a court shall refuse to enforce all of the
          separate covenants deemed included herein because, taken together, they are more extensive than necessary to assure the Company of the intended benefit of this Agreement, it is expressly understood and agreed among the parties hereto that those
          of such covenants that, if eliminated, would permit the remaining separate covenants to be enforced in such proceeding shall, for the purpose of such proceeding, be deemed eliminated from the provisions hereof.

          will be interpreted so that such payments and benefits so comply or are exempt. For all purposes of this Agreement, references to Executive’s “termination of employment” will be deemed to refer to Executive’s “separation from service” within the meaning of Section
          409A.

        

        

        For purposes of this Agreement, “Section 409A” will mean Section 409A of the Internal Revenue Code, as
          amended, and any regulations and other guidance promulgated thereunder and any applicable state law equivalent.

                Other Employment Matters

              


        

        

        Executive shall disclose to the Company any and all agreements relating to Executive’s prior employment that may affect Executive’s eligibility to be employed by the Company or limit the manner in which Executive may be employed. Unless Executive has informed the Company otherwise in writing, it is the Company’s
          understanding that any such agreements will not prevent Executive from performing the duties of Executive’s position and Executive represents that such is the case. Moreover, Executive agrees that, during the
          term of Executive’s employment with the Company, Executive will devote Executive’s full business efforts and time to the Company and Executive will not engage in any other
          employment, occupation, consulting or other business activity that conflict with Executive’s obligations to the Company.

        

        

        
          
            


        

        If Executive serves on the board of directors of any other company or entity, Executive shall provide the Company with a list of such companies or entities. If the Board reasonably
          deems such companies or entities to be competitors, customers or suppliers or Executive’s service on such board to otherwise represent a conflict of interest with Executive’s
          obligations to the Company, Executive will be required to resign Executive’s directorship with such companies or entities at the reasonable request of the Board. Executive agrees not to bring any third party
          confidential information to the Company, including that of Executive’s former employers, and that in performing Executive’s duties for the Company, Executive will not in
          any way utilize any such information.

        

        

        As a Company employee, Executive will be expected to follow the Company’s policies and procedures.

                Arbitration

              


        

        

        Any and all disputes that arise out of Executive’s employment or the terms of this Agreement shall be resolved through final and binding
          arbitration, as specified herein. This shall include, without limitation, disputes relating to this Agreement, Executive’s employment by the Company or the termination thereof, the stock options and other
          compensation and benefits granted to Executive, claims for breach of contract or breach of the covenant of good faith and fair dealing, and any claims for discrimination or other claims under any federal, state, or local law or regulation
          concerning in any way Executive’s employment with the Company or its termination. The only claims not covered by this Section are (i) claims for benefits under the workers’
          compensation laws or claims for unemployment insurance, and (ii) claims for alleged breach of any provision of Executive’s PHA, or otherwise that related to the Company’s
          intellectual property or confidential information. Binding arbitration will be conducted in New York County, New York, in accordance with JAMS Rules for Resolution of Employment disputes then in effect. Each party will bear its own attorneys’ fees, unless otherwise permitted by law and so determined by the arbitrator. The arbitration shall be instead of any civil litigation. The arbitrator’s written decision shall
          set forth the essential findings upon which the decision and award is based, shall be final and binding and subject to judicial review by Executive and the Company only as required by law, and shall be enforceable by any court having jurisdiction
          thereof.

                Entire Agreement; Modification; Governing Law

              


        

        

        This Agreement and the documents incorporated herein by reference, specifically including any preexisting obligation of the Company toward the Executive with regards to compensation,
          option or other equity grants for periods after the Effective Date (together, the “Documents”) set forth the terms of Executive’s employment with the Company and supersede and extinguish any prior or concurrent representations or agreements including, but not limited to any representations made during Executive’s recruitment, interviews or pre-employment negotiations, whether written or oral. This Agreement may not be modified or amended except by a written agreement signed by an authorized representative of the Board. This Agreement
          will be governed by the internal substantive laws, but not the choice of law rules, of the State of Delaware. In the event that any provision hereof becomes or is declared by a court of competent jurisdiction to be illegal, unenforceable, or
          void, this Agreement will continue in full force and effect without such provision.

                Severability

              


        

        

        Whenever possible, each provision of this 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 invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or unenforceability will not affect any other provision or any other jurisdiction, but such invalid,
          illegal or unenforceable provision will be reformed, construed and enforced in such jurisdiction so as to render it valid, legal, and enforceable consistent with the intent of the parties insofar as possible.

          the same Agreement. Signatures transmitted via facsimile will be deemed the equivalent of originals.

        This Agreement is intended to bind and inure to the benefit of and be enforceable by Executive, the Company and their respective successors, assigns, heirs, executors and
          administrators, except that Executive may not assign any of his duties hereunder and Executive may not assign any of his rights hereunder without the prior written or electronic consent of the Company.
