If such question shall arise and the Executive shall fail to submit such certification, the Company’s determination of such issue shall be binding on the Executive. Nothing in this Section 3.01(b) shall be construed to waive the Executive’s rights, if any, under existing law including, without limitation, the Family and Medical Leave Act of 1993, 29 U.S.C. §2601 et seq. and the Americans with Disabilities Act, 42 U.S.C. § 12101 et seq. (c) Termination by the Company for Cause. The Company may terminate the Executive’s employment hereunder at any time for Cause. “Cause” shall exist with respect to the Executive for purposes of this Agreement if the Executive has:

Notwithstanding anything to the contrary contained herein, if the Executive is terminated by the Company for Cause, but an arbitrator or court makes a determination, which determination is not subject to further appeal or after any right to appeal has expired, that adequate grounds for Cause did not exist, then such termination shall be deemed a termination without Cause for all purposes hereunder. (d) Termination Without Cause. The Company may terminate the Executive’s employment hereunder at any time without Cause. A termination without Cause is any termination that does not: (i) constitute a termination by the Company for Cause under Section 3.01(c); (ii) result from the death or disability of the Executive under Sections 3.01(a) or (b); or (iii) result from the Executive’s resignation for any reason (including, without limitation, Executive’s resignation with or without Good Reason and any Accelerated Resignation (each, as defined below)).

Notwithstanding the foregoing, the Executive’s employment will not be deemed to have resigned for Good Reason unless (i) the Executive provides the Company with written notice setting forth in reasonable detail the facts and circumstances claimed by the Executive to constitute Good Reason within 30 days after the date of the occurrence of any event that the Executive knows or should reasonably have known to constitute Good Reason, (ii) the Company fails to cure such acts or omissions within 30 days following its receipt of such notice, and (iii) the effective date of the Executive’s termination for Good Reason occurs no later than 30 days after the expiration of the Company’s cure period.

Notwithstanding the foregoing, in the event that the Executive resigns for any reason (other than a resignation with Good Reason) and gives a Notice of Termination to the Company, the Company may unilaterally accelerate the Termination Date to any earlier effective date (an “Accelerated Resignation”) and such Accelerated Resignation shall not result in or be treated as a termination by the Company as of such earlier effective date for purposes of this Agreement.

Because the Executive’s services are unique and because the Executive has access to Confidential Information, the parties hereto agree that money damages would be an inadequate remedy for any breach of this Agreement.

The Company and the Executive agree that any dispute between or among them or their subsidiaries, affiliates or related entities arising out of, relating to or in connection with this Agreement or the Executive’s employment with the Company, will be resolved in accordance with a two-step dispute resolution procedure involving: (1) Step One: non-binding mediation, and (2) Step Two: binding arbitration under the Federal Arbitration Act, 9 U.S.C. section 1 et. seq., or state law, whichever is applicable. Any such mediation or arbitration hereunder shall be conducted in any forum and form agreed upon by the parties or, in the absence of such an agreement, under the auspices of the JAMS (f/k/a the Judicial Arbitration and Mediation Service) (“JAMS”) pursuant to its then current JAMS Employment Arbitration Rules & Procedures (a copy of which is available through JAM’s website, www.jamsadr.org) (the “JAMS Rules”). Notwithstanding anything to the contrary in the JAMS Rules, the mediation process (Step One) may be ended by either party to the dispute upon notice to the other party that it desires to terminate the mediation and proceed to the Step Two arbitration; provided, however, that neither party may so terminate the mediation process prior to the occurrence of at least one (1) mediation session with the mediator. No arbitration shall be initiated or take place with respect to a given dispute if the parties have successfully achieved a mutually agreed to resolution of the dispute as a result of the Step One mediation. The mediation session(s) and, if necessary, the arbitration hearing shall be held in Philadelphia, Pennsylvania or any other location mutually agreed to by the parties hereto. The arbitration (if the dispute is not resolved by mediation) will be conducted by a single JAMS arbitrator, mutually selected by the parties, as provided for by the JAMS Rules. If required by law, the Company will be responsible for the JAMS charges, including the costs of the mediator and arbitrator, otherwise the parties will share such charges equally. The Company and the Executive agree that the arbitrator shall apply the substantive law of Delaware to all state law claims and federal law to any federal law claims and that discovery shall be conducted in accordance with the JAMS Rules or as otherwise permitted by law as determined by the arbitrator. The arbitrator’s award shall consist of a written statement as to the disposition of each claim and the relief, if any, awarded on each claim. The Company

-13- and the Executive understand that the right to appeal or to seek modification of any ruling or award by the arbitrator is limited under state and federal law. Any award rendered by the arbitrator will be final and binding, and judgment may be entered on it in any court of competent jurisdiction in Philadelphia, Pennsylvania at the time the award is rendered or as otherwise provided by law. Nothing contained herein shall restrict either party from seeking temporary injunctive relief in a court of law. The arbitrators are not empowered to award damages in excess of compensatory damages and each party irrevocably waives any damages in excess of compensatory damages. Judgment upon any arbitration award may be entered into any court having jurisdiction thereof and the parties consent to the jurisdiction of any court of competent jurisdiction located in the Commonwealth of Pennsylvania. Each party shall bear its own legal and other fees and expenses in the event of a dispute hereunder. Section 5.06 GOVERNING LAW. THIS AGREEMENT SHALL BE DEEMED TO BE MADE IN THE STATE OF DELAWARE, INTERPRETATION, CONSTRUCTION AND PERFORMANCE OF THIS AGREEMENT IN ALL RESPECT SHALL BE GOVERNED BY THE LAWS OF THE STATE OF DELAWARE WITHOUT REGARD TO ITS PRINCIPLES OF CONFLICTS OF LAW. Section 5.07 Amendment; No Waiver. No provision of this Agreement may be amended, modified, waived or discharged except by a written document signed by the Executive and duly authorized officer of the Company. The failure of a party to insist upon strict adherence to any term of this Agreement on any occasion shall not be considered as a waiver of such party’s rights or deprive such party of the right thereafter to insist upon strict adherence to that term or any other term of this Agreement. No failure or delay by any party in exercising any right or power hereunder will operate as a waiver thereof, nor will any single or partial exercise of any other right or power. No agreement or representations, oral or otherwise, express or implied, with respect to the subject matter hereof have been made by any party, which are not set forth expressly in this Agreement. Section 5.08 280G; Limitations on Payments. (a) Notwithstanding any other provision of this Agreement, in the event that any payment or benefit received or to be received by the Executive (including any payment or benefit received in connection with a termination of the Executive’s employment, whether pursuant to the terms of this Agreement or any other plan, arrangement or agreement) (all such payments and benefits, including the payments and benefits under Section 3.03 hereof, being hereinafter referred to as the “Total Payments”) would be subject (in whole or part), to the excise tax imposed under Section 4999 of the Code (the “Excise Tax”), then, after taking into account any reduction in the Total Payments provided by reason of Section 280G of the Code in such other plan, arrangement or agreement, the cash severance payments under this Agreement shall first be reduced, and the noncash severance payments hereunder shall thereafter be reduced, to the extent necessary so that no portion of the Total Payments is subject to the Excise Tax but only if (i) the net amount of such Total Payments, as so reduced (and after subtracting the net amount of federal, state and local income taxes on such reduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such reduced Total Payments) is greater than or equal to (ii) the net amount of such Total Payments without such reduction (but after subtracting the net amount of federal, state and local income taxes on such

-14- Total Payments and the amount of Excise Tax to which the Executive would be subject in respect of such unreduced Total Payments and after taking into account the phase out of itemized deductions and personal exemptions attributable to such unreduced Total Payments). In all cases, if there are any reductions to the Total Payments under this paragraph, the reduction shall be performed in a manner which results in the greatest after-tax amount being retained by the Executive and in manner which comports with Section 409A. (b) For purposes of determining whether and the extent to which the Total Payments will be subject to the Excise Tax, (i) no portion of the Total Payments the receipt or enjoyment of which the Executive shall have waived at such time and in such manner as not to constitute a “payment” within the meaning of Section 280G(b) of the Code shall be taken into account; (ii) no portion of the Total Payments shall be taken into account which, in the written opinion of an independent, nationally recognized accounting firm (the “Independent Advisors”) selected by the Company (provided however that Independent Advisors may not without the Executive’s written consent be the firm which serves as the auditor for the ultimate parent of the entity acquiring the Company) does not constitute a “parachute payment” within the meaning of Section 280G(b)(2) of the Code (including by reason of Section 280G(b)(4)(A) of the Code) and, in calculating the Excise Tax, no portion of such Total Payments shall be taken into account which, in the opinion of Independent Advisors, constitutes reasonable compensation for services actually rendered, within the meaning of Section 280G(b)(4)(B) of the Code, in excess of the “base amount” (as defined in Section 280G(b)(3) of the Code) allocable to such reasonable compensation; and (iii) the value of any non-cash benefit or any deferred payment or benefit included in the Total Payments shall be determined by the Independent Advisors in accordance with the principles of Sections 280G(d)(3) and (4) of the Code. Section 5.09 Severability. If any term or provision of this Agreement is invalid, illegal or incapable of being enforced by any applicable law or public policy, all other conditions and provisions of this Agreement shall nonetheless remain in full force and effect so long as the economic and legal substance of the transactions contemplated by this Agreement is not affected in any manner materially adverse to any party. Upon any such determination that any term or other provision is invalid, illegal or incapable of being enforced, the parties hereto shall negotiate in good faith to modify this Agreement so as to effect the original intent of the parties as closely as possible in a mutually acceptable manner in order that the transactions contemplated hereby be consummated as originally contemplated to the fullest extent possible. Section 5.10 Survival. The rights and obligations of the parties under the provisions of this Agreement that relate to post-termination obligations shall survive and remain binding and enforceable, notwithstanding the expiration of the term of this Agreement, the termination of the Executive’s employment with the Company for any reason or any settlement of the financial rights and obligations arising from the Executive’s employment hereunder, to the extent necessary to preserve the intended benefits of such provisions. Section 5.11 Notices. All notices and other communications required or permitted by this Agreement will be made in writing and all such notices and communications will be deemed to have been duly given when delivered or (unless otherwise specified) emailed, mailed by United States certified or registered mail, return receipt requested, postage prepaid, addressed, if to the

-15- Company, at its principal office, and if to the Executive, at the Executive’s last address on file with the Company. Either party may change such address from time to time by notice to the other. Section 5.12 Headings and References. The headings of this Agreement are inserted for convenience only and neither constitute a part of this Agreement nor affect in any way the meaning or interpretation of this Agreement. When a reference in this Agreement is made to a Section, such reference shall be to a Section of this Agreement unless otherwise indicated. Section 5.13 Counterparts. This Agreement may be executed in one or more counterparts (including via facsimile), each of which shall be deemed to be an original, but all of which together shall constitute one and the same instrument.

- 17 - US-DOCS\117251870.4 EXHIBIT A GENERAL RELEASE AND WAIVER I, Jeffrey M. Dayno, M.D., in consideration of and subject to the performance by Harmony Biosciences, LLC, a Delaware limited liability company (the “Company”), of its obligations under the Executive Employment Agreement, dated as of April [xx], 2023 (together with any amendments thereto, the “Agreement”), do hereby release and forever discharge as of the date hereof each of the Company, the other members of the Company Group, their respective affiliates and subsidiaries and all present and former members, managers, directors, officers, agents, representatives, employees, successors and assigns thereof (collectively, the “Released Parties”) to the extent provided below. Capitalized terms used but not defined herein shall have the meanings given to them in the Agreement. 1. I understand that the payment of the payments pursuant to Section 3.03 [and Section 3.04, if applicable] of the Agreement (the “Severance Payments”) represent, in part, consideration for signing this General Release and Waiver and is not salary, wages or benefits to which I was already entitled. I understand and agree that I will not receive the Severance Payments (a) unless I execute this General Release and Waiver and do not revoke this General Release and Waiver within the time period permitted hereafter, (b) if I breach this General Release and Waiver in any material respect or (c) if I breach any provision of Article IV of the Agreement. Such payment will not be considered compensation for purposes of any employee benefit plan, program, policy or arrangement maintained or hereafter established by the Company, the Company Group or any of their respective affiliates, subsidiaries or successors. Subject to the proviso set forth at the end of Section 2 below, I also acknowledge and represent that I have received all payments and benefits that I am entitled to receive (as of the date hereof) by virtue of any employment by the Company, the Company Group or their respective affiliates or subsidiaries. 2. Except as provided in Section 4 below and except for the provisions of the Agreement which expressly survive the termination of my employment with the Company, the Company Group or their respective affiliates or subsidiaries, I knowingly and voluntarily (for myself, my heirs, executors, attorneys, representatives, agents, administrators and assigns) fully and unconditionally release and forever discharge the Company, the Company Group and the other Released Parties from any and all claims, suits, controversies, actions, causes of action, cross-claims, counter-claims, demands, debts, compensatory damages, liquidated damages, punitive or exemplary damages, other damages, claims for costs and attorneys’ fees, or liabilities of any nature whatsoever in law and in equity, both past and present (through the date this General Release and Waiver becomes effective and enforceable) and whether known or unknown, suspected, or claimed against the Company, the Company Group or any other Released Parties which I, my spouse, or any of my heirs, executors, attorneys, representatives, agents, administrators or assigns, may have, which arise out of or are connected with my employment with, or my separation or termination from, the Company, the Company Group or their respective affiliates or subsidiaries (including, but not limited to, any allegation, claim or violation, arising under: Title VII of the Civil Rights Act of 1964, as amended; the Civil Rights Act of 1991; the Age Discrimination in Employment Act of 1967, as amended (including the

- 18 - US-DOCS\117251870.4 Older Workers Benefit Protection Act); the Equal Pay Act of 1963, as amended; the Americans with Disabilities Act of 1990; the Family and Medical Leave Act of 1993; the Worker Adjustment Retraining and Notification Act; the Employee Retirement Income Security Act of 1974; Illinois and/or Pennsylvania Labor Laws or their state or local counterparts; or under any other federal, state or local civil or human rights law, or under any other local, state, or federal law, regulation or ordinance; or under any public policy, contract or tort, or under common law; or arising under any employment policies, practices or procedures of the Company, the Company Group or any of or any of their respective affiliates, subsidiaries or successors; or any claim for wrongful discharge, breach of contract, infliction of emotional distress, defamation; or any claim for costs, fees, or other expenses, including attorneys’ fees incurred in these matters) (all of the foregoing collectively referred to herein as the “Claims”); provided, however, that this General Release and Waiver does not waive or release any rights or claims that I may have under or against the Released Parties arising out of any of the following (which shall be excluded from the definition of “Claims”): (a) any claims for the payment of earned but unpaid Base Salary through the Termination Date (b) any rights of indemnification or to advancement of expenses, whether pursuant to applicable law or contract, (c) any rights as an owner of equity in a Released Party, (d) any other vested or accrued amounts to which I am entitled under the express terms of any applicable executive or employee benefit plan, or (e) any claim that may not be waived as a matter of law, including, to the extent applicable, any right to receive an award for information provided to a government agency (except with respect to any discrimination charge filed with or investigation conducted by the Equal Employment Opportunity Commission (the “EEOC”) and any similar state or local agency). For the purpose of implementing a full, knowing and complete release and discharge of the aforementioned Released Parties, I expressly acknowledge that this General Release and Waiver is intended to include in its effect, without limitation, all claims which I do not know or suspect to exist in my favor at the time of execution hereof, and that the Agreement contemplates the extinguishment of any such claim or claims. 3. I represent that I have made no assignment or transfer of any right, claim, demand, cause of action, or other matter covered by Section 2 above. 4. I agree that this General Release and Waiver does not waive or release any rights or claims that I may have under the Age Discrimination in Employment Act of 1967 which arise after the date I execute this General Release and Waiver. I acknowledge and agree that my separation from employment with the Company, the Company Group or their respective affiliates or subsidiaries in compliance with the terms of the Agreement shall not serve as the basis for any claim or action (including, without limitation, any claim under the Age Discrimination in Employment Act of 1967). 5. In signing this General Release and Waiver, I acknowledge and intend that it shall be effective as a bar to each and every one of the Claims hereinabove mentioned or implied. I expressly consent that this General Release and Waiver shall be given full force and effect according to each and all of its express terms and provisions, including those relating to unknown and unsuspected Claims (notwithstanding any state statute that expressly limits the effectiveness of a general release of unknown, unsuspected or unanticipated Claims), if any, as well as those relating to any other Claims hereinabove mentioned or implied. I

- 19 - US-DOCS\117251870.4 acknowledge and agree that this waiver is an essential and material term of this General Release and Waiver and that without such waiver the Company would not have agreed to the terms of the Agreement. I further agree that in the event I should bring a Claim seeking damages against the Company, the Company Group or any other Released Party, or in the event I should seek to recover against Company, the Company Group or any other Released Party in any Claim brought by a governmental agency on my behalf, this General Release and Waiver shall serve as a complete defense to such Claims. I further waive any right to recovery in a proceeding instituted on my behalf by an administrative agency or other entity regarding my employment with, or separation from, the Company, the Company Group or their respective affiliates or subsidiaries. I further agree that I am not aware of any pending charge or complaint of the type described in Section 2 above as of the execution of this General Release and Waiver except for _________________. 6. I represent that I am not aware of any Claim by me other than the claims that are released by this Agreement. I agree to expressly waive any rights I may have under any state statute that expressly limits the effectiveness of a general release of unknown, unsuspected or unanticipated Claims, as well as under any other statute or common law principles of similar effect. 7. I agree that neither this General Release and Waiver, nor the furnishing of the consideration for this General Release and Waiver, shall be deemed or construed at any time to be an admission by the Company, the Company Group, any other Released Party or myself of any improper or unlawful conduct. 8. I agree that I will forfeit the Severance Payments payable by the Company pursuant to the Agreement if I challenge the validity of this General Release and Waiver, provided, however, that the foregoing shall not release any right to challenge, under the Older Worker’s Benefit Protection Act, the knowing and voluntary nature of the release of any age claims in this General Release and Waiver, in court or before the EEOC or any right to file an administrative charge with the EEOC or any other similar federal, state, or local agency (provided, that any right to recover monetary damages in any such proceeding shall be hereby released and waived). 9. I also agree that if I violate this General Release and Waiver by suing the Company, the Company Group or the other Released Parties in respect of a Claim, I will pay all reasonable costs and expenses of defending against the suit incurred by the Released Parties in the event that they are the prevailing party, including reasonable attorneys’ fees, and return the Severance Payments received by me pursuant to the Agreement. I understand that, if I prevail in any action against the Company, the Company Group or any other Released Parties in respect of a Claim, Company will pay all of my reasonable costs and expenses that I incurred in conjunction with such action, including reasonable attorneys’ fees. 10. I acknowledge and reaffirm my obligation to abide by the covenants set forth Article IV of the Agreement. I further agree that as of the date hereof, I have returned to the Company any and all property, tangible or intangible, relating to the Business, which I possessed or had control over at any time (including, but not limited to, company-provided credit cards,

- 20 - US-DOCS\117251870.4 building or office access cards, keys, computer equipment, manuals, files, documents, records, software, customer data base and other data) and that I shall not retain any copies, compilations, extracts, excerpts, summaries or other notes of any such manuals, files, documents, records, software, customer data base or other data, except to the extent that I am entitled to retain such materials under the provisions of Article IV of the Agreement. 11. Nothing in this General Release and Waiver prohibits me from reporting possible violations of federal law or regulation to any governmental agency or entity, or making other disclosures, that are protected under the whistleblower provisions of federal law or regulation (or similar state laws) or receipt of awards thereunder. I will not need the prior authorization of the Board or the Company Chairman to make any such reports or disclosures, and I will not be required to notify the Company that I have made such reports or disclosures, provided, that nothing shall waive any attorney client or similar privilege of the Company or the Company Group. I will not be held criminally or civilly liable under any federal or state trade secret law for any disclosure of a trade secret that is made (i) in confidence to a federal, state or local government official, either directly or indirectly, or to an attorney and solely for the purpose of reporting or investigating a suspected violation of law, or (ii) in a complaint or other document that is filed under seal in a lawsuit or other proceeding. 12. Notwithstanding anything in this General Release and Waiver to the contrary, this General Release and Waiver shall not relinquish, diminish, or in any way affect any rights or claims arising out of any breach by the Company or by any other Released Party of the Agreement after the date hereof. 13. I hereby waive any reinstatement or future employment with the Company, the Company Group or any of their respective affiliates or subsidiaries and agree never to apply for employment or otherwise seek to be hired, rehired, employed, reemployed, or reinstated by Company, the Company Group or any of their respective affiliates or subsidiaries without the prior written approval of the Company. 14. Whenever possible, each provision of this General Release and Waiver, shall be interpreted in, such manner as to be effective and valid under applicable law, but if any provision of this General Release and Waiver 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 shall not affect any other provision or any other jurisdiction, but this General Release and Waiver shall be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or unenforceable provision had never been contained herein. Upon a finding by a court of competent jurisdiction that any release or agreement in this General Release and Waiver is illegal, void or unenforceable, I agree, at the Company’s option, to execute promptly a release and agreement that is legal and enforceable. My failure to comply with the obligations to promptly execute such release will constitute a material breach of this General Release and Waiver. BY SIGNING THIS GENERAL RELEASE AND WAIVER, I REPRESENT AND AGREE THAT:
