2.6 Participation in Long-Term Incentive Plan. Executive will be eligible to participate in the Company’s Long-Term Incentive Program (“LTIP-1”). The Board shall determine the portion of the LTIP-1 that will be allocated to Executive (“LTIP Grant”). The LTIP Grant will be awarded based on a plan to be developed by the Board. The vesting conditions of Executive’s LTIP Grant will be consistent with those applicable to other executive officers of the Company and are expected to vest based on achievement of a combination of specific service-based and performance-based vesting conditions, subject to the approval of the Board.

4.1 In General. The Executive’s employment may be terminated by the Company or by the Executive at any time upon sixty (60) days’ prior written notice to the other party; provided, however, that the Board may elect to waive such notice period or any portion thereof, in which case the Company will continue to pay the Base Salary for that portion of the notice period so waived. For clarity, the Company may only terminate the Executive’s employment through a resolution of the Board.

4.2 Termination by the Company for Cause. Notwithstanding the provisions of Section 4.1, the Company may terminate the Executive’s employment immediately for Cause upon written notice to the Executive setting forth in reasonable detail the nature of the Cause. For purposes of this Agreement, “Cause” means the occurrence of any of the following, as determined by the Board in its reasonable judgment: (i) the Executive’s willful and material failure to perform (other than by reason of disability), or substantial misconduct in the performance of, the Executive’s duties and responsibilities for the Company or any of its Affiliates which causes material harm to the Company; (ii) the Executive’s material and demonstrable breach of any provision of Section 3 or any other confidentiality, invention assignment or other restrictive covenant obligation set forth in any written agreement by and between the Executive and the Company or any of its Affiliates;(iii) the Executive’s material and demonstrable breach of any other provision of this Agreement or any other written agreement by and between the Executive and the Company or any of its Affiliates; (iv) the Executive’s willful and material violation of any applicable policy or code of conduct of the Company or any of its Affiliates, which violation causes material reputational or financial harm to the Company; or (v) the Executive’s indictment for, or plea of nolo contendere to, any felony or any crime involving moral turpitude. Notwithstanding anything to the contrary in the foregoing, a circumstance otherwise giving rise to Cause pursuant to the foregoing clause (i), (ii), (iii) or (iv), (X) if capable of cure, will not constitute Cause if cured by the Executive within twenty (20) days following the Company’s notice to the Executive thereof; provided, however, that the Company will not be required to provide any such notice or opportunity to cure with respect to any subsequent substantially similar or related conduct and (Y) for purposes of this definition, no act or failure to act on the part of Executive shall be considered “willful” unless the Board believes in good faith that such action or omission was done, or omitted to be done, by Executive in bad faith or

LEGAL\53952298\2

without the reasonable belief that Executive’s action or omission was in the best interest of the Company.

4.3 Resignation by the Executive for Good Reason. Notwithstanding the provisions of Section 4.1, the Executive may terminate the Executive’s employment for Good Reason upon written notice to the Company setting forth in reasonable detail the nature of the circumstances constituting Good Reason. For purposes of this Agreement, “Good Reason” means the occurrence of any of the following without the Executive’s consent: (i) a reduction in Base Salary of more than five percent (5%), other than an across-the-board reduction applicable to similarly situated executives of the Company; (ii) a permanent relocation of the Executive’s principal place of business that increases the Executive’s commute by more than twenty (20) miles in a single direction; (iii) Company effects a reduction in Executive’s title as Chief Business Officer or position as leader of functions over which Executive has management oversight and control on behalf of the Company and its Parent, Astra Space, Inc., as of the Amendment Effective Date (collectively, the “Functions”); (iv) Company causes Executive to report to any individual or group, other than the Chief Executive Officer of the Company prior to a Change of Control and the chief executive officer of the Ultimate Parent after a Change of Control, or (v) any material adverse change in Executive’s duties, responsibilities or authority as of the date of this Agreement or the assignment to Executive of duties or responsibilities that are materially inconsistent with Executive’s position as the leader of the Functions, which is not substantially remedied by the Company during the applicable cure period; provided, in each case, that (x) the Executive provides the Company with written notice of the circumstance constituting Good Reason within twenty (20) days following the Executive’s first knowledge thereof, (y) the Company fails to cure such circumstance within twenty (20) days following the receipt of such notice and (z) the Executive actually terminates employment within twenty (20) days following the expiration of such cure period.

“5.1 Final Compensation. In the event of termination of the Executive’s employment with the Company, howsoever occurring, the Company will pay the Executive (i) the Base Salary for the final payroll period of the Executive’s employment, through the date the Executive’s employment terminates (the “Termination Date”); (ii) payment of any earned, but unpaid Annual Bonus for the fiscal year preceding the year in which the termination occurs; (iii) compensation at the rate of the Base Salary for any vacation time accrued in accordance with the policies of the Company but not used as of the Termination Date; and (iv) reimbursement, in accordance with Section 2.7 hereof, for business expenses incurred by the Executive but not yet paid to the Executive as of the Termination Date, provided that the Executive submits all expenses and supporting documentation required within sixty (60) days of the Termination Date and that such expenses are reimbursable under Company policies then in effect (all of the foregoing, the “Final Compensation”).
