3. Withholding Taxes; COBRA; Accrued Benefits. Any payment under this Letter Agreement will be made less all applicable withholdings and deductions.

In addition, whether or not you sign the Release, you will receive (a) your accrued but unused paid time off, and (b) any unreimbursed business expenses through your Separation Date, payable as soon as practicable following the Separation Date in accordance with the Company policy.

5. Non-Disparagement. Subject to Section 6 of this Letter Agreement, you agree that you will not make or publish, or cause to be made or published, in the public domain, through any print or electronic media or otherwise, or through any third party, any statements or comments that disparage, injure or diminish (or that a reasonable person would expect would likely have the effect of disparaging, injuring, or diminishing) the reputation of the Company or any of its respective directors, officers, agents, members, or employees, consultants or representatives.

6. Permitted Disclosures.

(a) Nothing in this Letter Agreement or in any other agreement or arrangement between you and the Company shall (i) prohibit you from disclosing information about unlawful acts in the workplace, including, but not limited to, sexual harassment; (ii) prohibit you from voluntarily communicating with an attorney retained by you; (iii) prohibit you from initiating communications directly with, responding to any inquiries from, providing testimony before, reporting possible violations of law or regulation to, or filing a claim or assisting with an investigation directly with, law enforcement, a self-regulatory authority or a government agency or entity, including the U.S. Equal Employment Opportunity Commission, the District of Office of Human Rights, any state or local commission on human rights or similar entity, the Department of Justice, the Securities and Exchange Commission (“SEC”), the Congress, and any agency inspector general, or from making other disclosures that are protected under the whistleblower provisions of state or federal law or regulation; (iv) prohibit you from recovering a SEC whistleblower award as provided under Section 21F of the Securities Exchange Act of 1934; (v) waive your right to testify before or provide information (including confidential information of the Company) to an administrative, legislative or judicial proceeding concerning alleged violations of law in response to a subpoena, provided that you first promptly notify and provide the Company with the opportunity to seek, and join in its efforts at the sole expense of the Company, to challenge the subpoena or obtain a protective order limiting its disclosure or other appropriate remedy; or (vi) limit or prevent you from filing or disclosing any facts necessary to receive unemployment insurance, Medicaid or other public benefits to which you are entitled.

(b) Pursuant to 18 U.S.C. §1833(b), you shall not be held criminally or civilly liable under any Federal or State trade secret law for the disclosure of a trade secret of the Company that (i) is made (A) in confidence to a Federal, State, or local government official, either directly or indirectly, or to your attorney, and (B) solely for the purpose of reporting or investigating a suspected violation of law; or (ii) is made in a complaint or other document that is filed under seal in a lawsuit or other proceeding. If you file a lawsuit for retaliation by the Company for reporting a suspected violation of law, you may disclose the trade secret to your attorney and use the trade secret information in the court proceeding, if you (1) file any document containing the trade secret under seal, and (2) do not disclose the trade secret, except pursuant to court order. Nothing in this Agreement is intended to conflict with 18 U.S.C. §1833(b) or create liability for disclosures of trade secrets that are expressly allowed by such section.

All Disputes shall be resolved exclusively by arbitration administered by the Judicial Arbitration and Mediation Services (“JAMS”) under the JAMS Comprehensive Arbitration Rules & Procedures then in effect, available at www.jamsadr.com (the “JAMS Rules”).
	(b)	Any arbitration proceeding brought under this Letter Agreement shall be conducted in Melbourne, Florida, or another mutually agreed upon location before one arbitrator selected in accordance with the JAMS Rules. The Company will pay for any administrative or hearing fees charged by the arbitrator or JAMS, except that you shall pay any filing fees associated with any arbitration that you initiate (but only so much of the filing fees as you would have instead paid, had you filed a complaint in a court of law). Each party to any Dispute shall pay its own expenses, including attorneys’ fees; provided, that, the arbitrator shall award the prevailing party reasonable costs and attorneys’ fees incurred but shall not be able to award any special or punitive damages. The arbitrator shall issue a decision or award in writing, stating the essential findings of fact and conclusions of law.

	(c)	Any judgment on or enforcement of any award, including an award providing for interim or permanent injunctive relief, rendered by the arbitrator may be entered, enforced or appealed from in any court of competent jurisdiction.

	(d)	It is part of the essence of this Letter Agreement that any Disputes hereunder shall be resolved expeditiously and as confidentially as possible. Accordingly, you and the Company agree that all proceedings in any arbitration shall be conducted under seal and kept strictly confidential. In that regard, no party shall use, disclose or permit the disclosure of any information, evidence or documents produced by any other party in the arbitration proceedings or about the existence, contents or results of the proceedings except as may be required by any legal process, as required in an action in aid of arbitration or for enforcement of or appeal from an arbitral award or as may be permitted by the arbitrator for the preparation and conduct of the arbitration proceedings. Before making any disclosure permitted by the preceding sentence, the party intending to make such disclosure shall give the other party reasonable written notice of the intended disclosure and afford such other party a reasonable opportunity to protect its interests.
	(e)	Notwithstanding the provisions of this Section 18, the terms of Section 6(g) of the Employment Agreement (“Remedies for Breach”) are incorporated by reference herein and remain in full force and effect.
