Separation Agreement with Donald Closser

On November 16, 2022, IronNet, Inc. (the “Company”) and Donald Closser, the Company’s Chief Product Officer, mutually agreed to Mr. Closser’s separation from the Company, effective as of November 18, 2022 (the “Separation Date”). The Company will not fill the vacancy at this time, and GEN (Ret.) Keith Alexander, Founder and Chief Executive Officer, will oversee the Company’s product function. The Company and Mr. Closser also entered into a Separation Agreement (the “Separation Agreement”) pursuant to which Mr. Closser has agreed to provide the Company with a full release of claims and provide transition services as may be requested by the Company. Pursuant to the Separation Agreement, and subject to Mr. Closser allowing the release to become irrevocable, the Company has agreed to provide Mr. Closser the following severance benefits:

•

if Mr. Closser timely elects continued health insurance coverage under COBRA, the Company will pay, subject to applicable regulations, the COBRA premium payments on Mr. Closser’s behalf sufficient to continue coverage for Mr. Closser and his covered dependents at its current level for up to six (6) months or, if earlier, until such time as Mr. Closser becomes eligible for health insurance at another employer or is otherwise ineligible for COBRA; and

•

acceleration of vesting and settlement of restricted stock units (“RSUs”) held by Mr. Closser covering a total of 398,868 shares of common stock that were outstanding as of the Separation Date and had been granted pursuant to the Company’s 2014 Stock Incentive Plan and 2021 Equity Incentive Plan, respectively; the shares of common stock will be granted to Mr. Closser upon settlement of the RSUs no later than December 31, 2022, and all of Mr. Closser’s remaining RSUs that were not vested as of the Separation Date will be forfeited.

The severance benefits payable to Mr. Closser under the Separation Agreement are in lieu of any severance payments and other benefits to which Mr. Closser would have otherwise been entitled to under the terms of his Employment Agreement with the Company dated September 19, 2019 (the “Employment Agreement”), with the exception of certain change of control protections set forth in the Employment Agreement. The foregoing summary of the Separation Agreement is qualified in its entirety by reference to the full text of the Separation Agreement, a copy of which is filed as Exhibit 10.1 to this Current Report on Form 8-K and incorporated by reference herein.

Re: Separation Agreement

Dear Don:

This letter sets forth the substance of the separation agreement (the “Agreement”) which IronNet Cybersecurity, Inc. (the “Company”) is offering to you to aid in your employment transition.

1. Separation. The Company has accepted your resignation effective November 18, 2022 (the “Separation Date”). You and the Company agree that as of the Separation Date, you will be deemed to have resigned from your role as an officer of the Company and from any other positions you hold with the Company and/or any of the Company Parties (as defined below). You agree to complete such documentation as may be reasonably requested by the Company to effect your resignation from these positions.

2. Accrued Salary. Within six (6) days following the Separation Date, the Company will pay you all accrued salary earned through the Separation Date, subject to standard payroll deductions and withholdings. You will receive these payments regardless of whether or not you sign this Agreement.

3. Severance Benefits. As you know, you are eligible for severance pursuant to Section 6.1 of the Amended and Restated Executive Employment Agreement between you and the Company dated June 14, 2022 (the “Employment Agreement”); provided, however, that per this Agreement the Company is offering you severance benefits comparable to the benefits contained in your Employment Agreement. If you execute and do not revoke this Agreement, and fully comply with your obligations hereunder, the Company will provide you with the following “Severance Benefits,” in full satisfaction of the obligations under the Employment Agreement:

(a) On the Separation Date and subject to your termination from employment (but immediately prior the effective time of such termination), the Company’s Board of Directors (the “Board”) will accelerate the vesting of a number of your outstanding unvested RSUs (as defined below) that will result in the issuance to you of 259,027 additional shares of the Company’s common stock which is intended to supersede and is provided in lieu of the six (6) months’ severance pay that was provided for in Section 6.1(c)(i) of the Employment Agreement such that the number of additional RSUs subject to accelerated vesting under this provision is equivalent to the product of $165,000 (six months of your annual base salary as of the Separation Date) divided by $0.637 (which is the average closing stock price for the thirty trading days preceding and ending on November 10, 2022).

(b) As an additional severance benefit, if you are participating in the Company’s group health insurance plans and you timely elect continued coverage under the Consolidated Omnibus Budget Reconciliation Act of 1985 or any applicable state equivalent (“COBRA”), and timely execute and return this Agreement and allow it to become effective, the Company will pay

Don Closser

Page 2 of 9

the COBRA premium payments sufficient to continue your group coverage at its current level (including coverage for your eligible dependents, if applicable) until the earlier of: (A) six (6) months following the Separation Date, (B) the expiration of your eligibility for the continuation coverage under COBRA, or (C) such time as you become eligible for health insurance at another employer or through self-employment (such period from the Separation Date through the earliest of (A) through (C), the “COBRA Payment Period”). If you elect COBRA coverage and are not eligible for Company payments as described above, you will be responsible to pay the premiums. Notwithstanding the foregoing, if at any time the Company determines, in its sole discretion, that the payment of the COBRA medical premiums would result in a violation of the nondiscrimination rules of Section 105(h)(2) of the Internal Revenue Code or any statute or regulation of similar effect (including but not limited to the 2010 Patient Protection and Affordable Care Act, as amended by the 2010 Health Care and Education Reconciliation Act), then provided you remain eligible in accordance with this Section 3(b), in lieu of providing the COBRA medical premiums, the Company will instead pay you on the last day of each remaining month of the COBRA Payment Period, a fully taxable cash payment equal to the COBRA medical premiums for that month, subject to applicable tax withholdings for the remainder of the COBRA Payment Period, plus an additional payment such that the net amount retained by you after deduction for all payments required to be made to any federal, state or local authorities equals the amount of the monthly COBRA premium. In the event you become covered under another employer’s group health plan or otherwise cease to be eligible for COBRA coverage, you must immediately notify the Company within five (5) days of obtaining such coverage, and the Company’s obligation to pay COBRA premiums shall cease.

(c) As described in Section 5 of this Agreement, the Company will also accelerate the vesting of certain outstanding restricted stock units (“RSUs”) that are held by you as of the Separation Date and which are subject to service-based vesting (in addition to the accelerated vesting under Section 3(a) above).

The Company is offering the Severance Benefits to you in reliance on Treasury Regulation Section 1.409A-1(b)(9) and the short-term deferral exemption in Treasury Regulation Section 1.409A-1(b)(4). Any payments made in reliance on Treasury Regulation Section 1.409A-1(b)(4) will be made not later than March 15, 2023. For purposes of Code Section 409A, your right to receive any installment payments under this letter (whether severance payments, reimbursements or otherwise) shall be treated as a right to receive a series of separate payments and, accordingly, each installment payment hereunder shall at all times be considered a separate and distinct payment.

4. Benefit Plans.

If you are currently participating in the Company’s group health insurance plans, your participation as an employee will end on the Separation Date. Thereafter, to the extent provided by the federal COBRA law or, if applicable, state insurance laws, and by the Company’s current group health insurance policies, you will be eligible to continue your group health insurance benefits at your own expense (other than as set forth in 3(b) above). Later, you may be able to convert to an individual policy through the provider of the Company’s health insurance, if you wish.

Your participation in other applicable insurance will cease as of the Separation Date.

Deductions for the 401(k) Plan will end with your last regular paycheck. You will receive information by mail concerning 401(k) plan rollover procedures should you be a participant in this program.

You have the right to continue your current Health Care Spending Account if you are participating in this program. Enclosed is the information concerning how to continue this benefit. Dependent Care Spending Accounts cannot be continued. Your last full Spending Account payroll deductions will be processed in the November 15, 2022 pay period. Unless you elect to continue your Health Care Spending Account, you will only be eligible to claim expenses that you incurred prior to the Separation Date.

5. RSUs.

(a) During your employment with the Company, you were awarded restricted stock units (“RSUs”) subject to time-based vesting pursuant to the terms of the Company’s 2014 Equity Incentive Plan and the 2021 Equity Incentive Plan, respectively (collectively, the “Plans”). The schedule in Exhibit B sets forth the RSUs in effect as of the Separation Date. Under the terms of the Plans and the agreements governing the RSUs (the “RSU Documents”), any additional vesting of the RSUs (except as provided below) will cease as of the Separation Date. Notwithstanding the above, under the terms of Section 6.1(c)(iv) of the Employment Agreement, if you execute this Agreement, allow it to become effective and fully comply with your obligations under this Agreement, the Board will accelerate the vesting of 139,841 unvested RSUs as of the Separation Date as illustrated in Exhibit B (76,323 RSUs from “Grant 646,” plus 1,018 RSUs from “Grant 962,” plus 62,500 RSUs from “Grant 1731”). For the avoidance of doubt, this amount is in addition to the accelerated vesting of 259,027 outstanding unvested RSUs as provided for in Section 3(a) above.

(b) All other restrictions and provisions of the Plans and RSU Documents, such as lock-up and settlement timing, will remain in effect; provided, however, that in order to facilitate an orderly transfer of the common stock underlying the RSUs subject to accelerated vesting herein, the Company may deliver and issue such common stock to you on any date or dates following the Separation Date that it determines to be administratively practicable, but in no case later than December 31, 2022, as well as an orderly sell to cover process so to not put an undue burden on the trading of the stock. You may elect, no later than the Separation Date, to pay cash to the Company to cover taxes (versus relying on the sell-to-cover). In such case of cash election, the settlement of shares shall happen as soon as reasonable after the Effective Date of this Agreement, but in no case later than December 31, 2022.

(c) Any RSUs that are not vested as of the Separation Date (after giving effect to the accelerated vesting under this Agreement and irrespective of any provisions of your Employment Agreement or other corporate events or other occurrences after the Effective Date) will be forfeited and will terminate without any payment to you.

6. Other Compensation or Benefits. You acknowledge that, except as expressly provided in this Agreement, you will not receive any additional compensation, severance or benefits after the Separation Date.

Don Closser

Page 4 of 9

7. Expense Reimbursements. You agree that, within ten (10) days of the Separation Date, you will submit your final documented expense reimbursement statement reflecting all business expenses you incurred through the Separation Date, if any, for which you seek reimbursement. The Company will reimburse you for reasonable business expenses pursuant to its regular business practice.

8. Return of Company Property. By the Separation Date, you agree to return to the Company all Company documents (and all copies thereof) and other Company property that you have had in your possession at any time, including, but not limited to, Company files, notes, drawings, records, business plans and forecasts, financial information, specifications, computer-recorded information, tangible property (including, but not limited to, computers), credit cards, entry cards, identification badges and keys; and, any materials of any kind that contain or embody any proprietary or confidential information of the Company (and all reproductions thereof). Please coordinate return of Company property with Fernando Maymi, CISO. Receipt of the Severance Benefits described in Section 3 of this Agreement is expressly conditioned upon return of all Company Property.

9. Proprietary Information and Post-Termination Obligations. Both during and after your employment you acknowledge your continuing obligations under your Employee Confidential Information, Inventions, Non-Competition and Non-Solicitation Agreement (attached as Exhibit C) not to use or disclose any confidential or proprietary information of the Company and to refrain from certain solicitation and competitive activities. If you have any doubts as to the scope of the restrictions in your agreement, you should contact Scott Alridge, Chief Legal Officer, immediately to assess your compliance. As you know, the Company will enforce its contract rights. Please familiarize yourself with the enclosed agreement which you signed. Confidential information that is also a “trade secret,” as defined by law, may be disclosed (A) if it 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. In addition, in the event that 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: (A) file any document containing the trade secret under seal; and (B) do not disclose the trade secret, except pursuant to court order.

10. Confidentiality. The provisions of this Agreement will be held in strictest confidence by you and will not be publicized or disclosed in any manner whatsoever; provided, however, that: (a) you may disclose this Agreement to your immediate family; (b) you may disclose this Agreement in confidence to your attorney, accountant, auditor, tax preparer, and financial advisor; and (c) you may disclose this Agreement insofar as such disclosure may be required by law. Notwithstanding the foregoing, nothing in this Agreement shall limit your right to voluntarily communicate with the Equal Employment Opportunity Commission, United States Department of Labor, the National Labor Relations Board, the Securities and Exchange Commission, other federal government agency or similar state or local agency or to discuss the terms and conditions of your employment with others to the extent expressly permitted by Section 7 of the National Labor Relations Act.

11. Non-Disparagement. You agree not to disparage the Company, and the Company’s attorneys, directors, managers, partners, employees, agents and affiliates, in any manner likely to be harmful to them or their business, business reputation or personal reputation; provided that you may respond accurately and fully to any question, inquiry or request for information when required by legal process. Notwithstanding the foregoing, nothing in this Agreement shall limit your right to voluntarily communicate with the Equal Employment Opportunity Commission, United States Department of Labor, the National Labor Relations Board, the Securities and Exchange Commission, other federal government agency or similar state or local agency or to discuss the terms and conditions of your employment with others to the extent expressly permitted by Section 7 of the National Labor Relations Act.

12. Cooperation after Termination. As set forth in Section 6.6 of the Employment Agreement, you agree to cooperate fully with the Company and its parent companies or affiliates in all matters relating to the winding up of your pending work including, but not limited to, the orderly transfer of any such work and institutional knowledge to such other persons as may be designated by the Company, by making yourself reasonably available during regular business hours.

13. Release. In exchange for the payments and other consideration under this Agreement, to which you would not otherwise be entitled, and except as otherwise set forth in this Agreement, you, on behalf of yourself and, to the extent permitted by law, on behalf of your spouse, heirs, executors, administrators, assigns, insurers, attorneys and other persons or entities, acting or purporting to act on your behalf (collectively, the “Employee Parties”), hereby generally and completely release, acquit and forever discharge the Company, its parents and subsidiaries, and its and their officers, directors, managers, partners, agents, representatives, employees, attorneys, shareholders, predecessors, successors, assigns, insurers and affiliates (the “Company Parties”) of and from any and all claims, liabilities, demands, contentions, actions, causes of action, suits, costs, expenses, attorneys’ fees, damages, indemnities, debts, judgments, levies, executions and obligations of every kind and nature, in law, equity, or otherwise, both known and unknown, suspected and unsuspected, disclosed and undisclosed, arising out of or in any way related to agreements, events, acts or conduct at any time prior to and including the execution date of this Agreement, including but not limited to: all such claims and demands directly or indirectly arising out of or in any way connected with your employment with the Company or the termination of that employment; claims or demands related to salary, bonuses, commissions, stock, stock options, or any other ownership interests in the Company, vacation pay, fringe benefits, expense reimbursements, severance pay, or any other form of compensation; claims pursuant to any federal, state or local law, statute, or cause of action; tort law; or contract law (individually a “Claim” and collectively “Claims”).

Also excluded from this Agreement are any Claims which cannot be waived by law, including, without limitation, any rights you may have under applicable workers’ compensation laws and your right, if applicable, to file or participate in an investigative proceeding of any federal, state or local governmental agency.

You further understand this Agreement does not limit your ability to voluntarily communicate with any Government Agencies or otherwise participate in any investigation or proceeding that may be conducted by any Government Agency, including providing documents or other information, without notice to the Company. While this Agreement does not limit your right to receive an award for information provided to the Securities and Exchange Commission, you understand and agree that, you are otherwise waiving, to the fullest extent permitted by law, any and all rights you may have to individual relief based on any Claims that you have released and any rights you have waived by signing this Agreement. If any Claim is not subject to release, to the extent permitted by law, you waive any right or ability to be a class or collective action representative or to otherwise participate in any putative or certified class, collective or multi-party action or proceeding based on such a Claim in which any of the Company Parties is a party. This Agreement does not abrogate your existing rights under any Company benefit plan or any plan or agreement related to equity ownership in the Company; however, it does waive, release and forever discharge Claims existing as of the date you execute this Agreement pursuant to any such plan or agreement.

You affirm that you have not filed or caused to be filed, and are not presently a party to, a Claim against any of the Company Parties. You further affirm that you have no known workplace injuries or occupational diseases.
