You understand and acknowledge that this Release is intended to be as broad as legally permissible and applies to both employment-related and non-employment- related claims up to the date you execute this Agreement. This paragraph does not release or waive any claims or rights that, as a matter of law, cannot be waived.

(b) You represent and warrant that you have no knowledge of any work-related injury or illness incurred while working for Pernix, that you have not filed a claim or an application for benefits under any workers' compensation law, that you do not have any such claim, and that you do not intend to make a workers' compensation claim or file an application for workers' compensation benefits.

(c) You represent and warrant that the Severance Payments and COBRA set forth in Section 3 are sufficient consideration for the release of claims in this Section 5.

6. You agree that by entering into this Agreement, Pernix and the Releasees do not admit any violation of law and specifically deny committing any such violation.

7. To the extent permitted by law, you represent and warrant that you are not aware of any proceeding that is pending before any court, administrative agency, governmental authority, regulatory agency or other regulatory authority that is based on, refers to, relates to or arises out of any claims or disagreement you may have had against, or believe you have had, with respect to your employment with Pernix or matters related thereto. If you have already filed a charge or claim with any federal, state or local agency, you are not required to dismiss that charge or claim to be eligible for the additional consideration offered by Pernix. You nonetheless warrant and represent, to the maximum extent permitted by law, that you have not filed any complaint, charge or proceeding of any type with any court, administrative agency, governmental authority, quasi-governmental authority or otherwise, based on, referring to or arising out of any occurrence or event that predates the execution of this Agreement and/or relating to your employment with any Releasee and/or the conclusion of that employment; provided, however, that nothing in this Agreement will prevent you from filing any action to enforce this Agreement. Furthermore, nothing in the Agreement shall affect your right to file a charge or complaint with the Equal Employment Opportunity Commission or the National Labor Relations Board or to participate or cooperate in such a matter; provided, however, that you agree and acknowledge that you are not entitled to, and explicitly relinquish and waive any claim or entitlement to, any monetary or personal recovery or benefit in connection with any charge or proceeding involving you. Should any judicial, regulatory or administrative complaint, investigation, charge, action or proceeding be brought against any Releasee on your behalf, or should any effort be made to include you as a party in any pending complaint, charge, investigation, action or proceeding, you agree that you will, at Pernix's expense, take all steps necessary and lawful to opt out, abandon and disclaim interest in such complaint, charge, action, investigation or proceeding. Further, you agree that you will not testify, assist or participate (except in response to judicial, regulatory or administrative order or subpoena, court order or other legal process or as otherwise required, and not merely permitted, by law) in any lawsuit, administrative action, or any judicial, regulatory or administrative proceeding or investigation brought against any Releasee. Pernix agrees that in the event you are called to testify in any proceeding with regard to any events during your employment with Pernix, Pernix will furnish you with counsel of Pernix's choice and reasonably acceptable to you, at Pernix's expense. The parties agree that certain matters in which you have been involved during your employment may necessitate your cooperation with Pernix in the future. Accordingly, you shall cooperate with Pernix in connection with matters arising out of your service to the Company, including internal investigations. Pernix shall reimburse you for reasonable expenses incurred and a reasonable daily rate agreed upon by the parties in connection with such cooperation (for the sake of clarity, Pernix will not be required to reimburse you for expenses incurred or pay you a reasonable daily rate if you are subpoenaed to testify on behalf of a party other than Pernix). You agree that, to the extent permitted by law, you will promptly notify Pernix if (i) you learn that a complaint, charge, action, investigation or proceeding has been filed against any Releasee, or (ii) you receive a notice or subpoena to testify, assist or participate in any lawsuit, administrative action, or any judicial, regulatory or administrative proceeding or investigation brought against any Releasee. You shall be covered by any Company insurance policies and procedures in effect from time to time that apply to former employees in the position that you held with the Company.

8. You acknowledge that prior to the Separation Date, you disclosed to Pernix to the best of your knowledge, in accordance with applicable policies and procedures, any and all information relevant to any investigation of Pernix business practices conducted by any government agency, and/or relevant to any existing litigation involving Pernix, whether administrative, civil or criminal in nature, and you are unaware of any allegations of fraud or criminal acts relating to current or former employees of the Company that have not been disclosed to the Company.

9. You further represent and warrant that in your capacity as an employee of Pernix, you are not aware of any reason to believe that Pernix or any of its affiliated companies and their respective officers, directors, agents or employees had taken or failed to take any action in any way directly or indirectly connected with its sales, marketing and billing operations, or otherwise that would cause it to be in violation of any Medicare, Medicaid or any other reimbursement program, or third-party-payer or other contract based upon or related to the products and/or services provided. You further represent and warrant that in your capacity as an employee of Pernix, you are not aware of any reason to believe that Pernix or any of its affiliated companies and their respective officers, directors, agents or employees had taken or failed to take any action in any way directly or indirectly connected with its sales, marketing and billing operations that would cause it to be in violation of any applicable federal, state, local or other law.

10. You acknowledge that, during your employment with Pernix, you acquired certain confidential, proprietary and trade secret information regarding the Releasees including, without limitation, non-public patient lists and information relating to the sources of patients, financial, personnel, and patient information, and other non-public confidential information concerning the business and affairs of suppliers, creditors, lenders, shareholders and patients of Pernix and its affiliates, as well as confidential information protected by HIPAA ("Confidential Information"). You acknowledge that you have not retained any written or other tangible material concerning any Confidential Information, whether located on your own personal computer or elsewhere. You agree to keep strictly confidential and not disclose any Confidential Information. You understand and acknowledge that your obligations under this Agreement with regard to any particular Confidential Information commenced upon the Separation Date and shall continue hereafter until such time as such Confidential Information has become public knowledge other than as a result of your breach of this Agreement or breach by those acting with you or on your behalf.

11. You agree to return promptly all Pernix property including, without limitation, all access passes, cell phones, personal digital assistants (PDAs), keys, laptops computers, credit cards, hardware, software, files, papers, memoranda, letters, handbooks, manuals, computer generated reports, patient lists and other tools or products of your employment (including copies) whether prepared by you or others.

12. For a period of one (1) year commencing on your Separation Date (the "Restricted Period"), you agree to not directly or indirectly, in any capacity, solicit for hire, attempt to hire, encourage or recommend for hire, or hire or employ, or conspire with, or aid or abet any third party in the solicitation, hiring or employment, of, any individual who is a Pernix employee, agent, consultant, or representative at the time of your separation from Pernix or was so employed at any time within one (1) year of your Separation Date. In the event of a violation of this Section 12, the length of the Restricted Period shall be extended by an amount of time equal to the period of time during which a violation of this Section 12 is deemed by a court of competent jurisdiction to have occurred (including any period required for litigation during which Pernix seeks to enforce such covenant).

13. You agree that you will not publicly or privately disparage Releasees or any of Pernix's officers, employees or affiliates, or the products, services, business, operations, personnel policies or procedures of any of them by any means, including, but not limited to, via the Internet or other media. Pernix will not disparage you or your performance by any means, including, but not limited to, via the Internet or other media.

14. You will have up to twenty-one (21) calendar days from the date you receive this Agreement to consider its terms and return it to Human Resources at Pernix. You acknowledge that if you fail to provide Pernix with the executed Agreement by the close of business on the twenty-first (21st) calendar day, this Agreement will be null and void.

15. During this twenty-one (21) calendar day period and before signing below, you are advised to consult with an attorney regarding the terms of this Agreement, at your own expense. The terms of the offer set forth herein will expire at the conclusion of the twenty-first (21st) calendar day period, if not accepted during that period of time. You may sign the Agreement prior to the conclusion of the twenty-first (21st) calendar day period. If you elect to do so, you acknowledge that you have done so voluntarily. Your signature below indicates that you are entering into this Agreement freely, knowingly and voluntarily, with a full understanding of its terms. You also acknowledge that you will have seven (7) calendar days from the date you sign this Agreement to revoke the Agreement by notifying the undersigned, at Pernix, in writing prior to the expiration of the seven (7) calendar day period.

16. (a) This Agreement constitutes and contains our complete understanding with respect to the subject matter addressed in this Agreement and supersedes and replaces all prior negotiations, agreements and representations, if any, whether written or oral, concerning the subject matter of this Agreement, except for the Confidentiality and Non-Competition Agreement executed by the parties on August 14, 2015; provided, however, as of the Separation Date Sections IV and V of such Agreement shall terminate and be of no further force and effect. The parties have executed this Agreement with full knowledge of any and all rights they may have, and they hereby assume the risk of any mistake of fact in connection with the true facts involved, or with regard to any facts that are now unknown to them.

(b) If any provision of the Agreement is held to be illegal, void, or unenforceable, such provision shall be of no force or effect. The illegality or unenforceability of such provision, however, shall have no effect upon, and shall not impair the legality or enforceability of, any other provision of this Agreement. Upon any finding by a court of competent jurisdiction that a release or waiver of claims or rights or a covenant provided for herein is illegal, void, or unenforceable, you agree, upon Pernix's request, promptly to execute a release, waiver, and/or covenant satisfactory to the Releasees that is legal and enforceable to the fullest extent legally permitted.

17. (a) Any controversy or dispute arising out of or relating to this Agreement, arising out of or relating to any aspect of the relationship between us, or to the interpretation of this Agreement, shall be settled exclusively by arbitration conducted in New Jersey, unless otherwise mutually agreed upon, before a single arbitrator in accordance with the employment arbitration rules of the American Arbitration Association ("AAA") then in effect and with discovery permitted by both parties in accordance with such rules. The award of the arbitrator shall be final and binding, and judgment may be entered on the arbitrator's award in any court having jurisdiction. In addition to any other relief awarded to the prevailing party in any such arbitration, the non-prevailing party in any such arbitration shall be obligated to pay any attorney's fees and costs incurred by the prevailing party in such action. This arbitration provision does not preclude you from bringing issues to the attention of federal, state, or local agencies. Such agencies can, if the law allows, seek relief against us on your behalf. The arbitrator may award declaratory or injunctive relief only in favor of the individual party seeking relief and only to the extent necessary to provide relief warranted by that party's individual claim. You and Pernix agree that each may bring claims against the other only in your or its individual capacity, and not as a plaintiff or class member in any purported class or representative proceeding. You agree that by entering into this Agreement, you and Pernix are each waiving the right to a trial by jury or to participate in a class action.

(b) This Agreement shall be construed and enforced in accordance with, and governed by, the laws of the State of New Jersey, without regard to conflict of laws principles. If any clause of this Agreement should ever be determined to be unenforceable, it is agreed that this will not affect the enforceability of any other clause or the remainder of this Agreement.

(c) This Agreement may be entered into any arbitral (or other necessary) proceeding to prove that a settlement was reached and to establish the material terms thereof, so long as application is first made to file it under seal.

(d) No waiver by either of the parties of any breach by the other party of any condition or provision of this Agreement to be performed by the other party shall be deemed a waiver of any similar or dissimilar provision or condition at the same or any prior or subsequent time.

18. By signing this Agreement, you acknowledge that: (1) you have read this Agreement completely; (2) you have had an opportunity to consider the terms of this Agreement for at least twenty-one (21) calendar days and understand you have seven (7) calendar days to revoke your agreement after you sign it; (3) you have been advised to consult with an attorney of your choice to explain the Agreement and its consequences; (4) you know that you are giving up important legal rights by signing this Agreement, including releasing both known and unknown claims; (5) you have not relied on any representation or statement that is not set forth in this Agreement; (6) you understand and intend everything that you have agreed to in this Agreement, and you agree to all of its terms; and (7) you have signed this Agreement voluntarily and entirely of your own free will.

UNDERSTOOD, AGREED AND ACCEPTED:
