11.2 Termination for Cause. This Agreement and/or any Task Order issued under it may be terminated by either party (reserving
cumulatively all other rights and remedies at law or in equity unless expressly stated herein) in the event the other party has materially breached this Agreement or any Task Order (i) upon receipt of written notice thereof if such material
breach is incapable of cure; or (ii) upon the expiration of thirty (30) days (or such additional cure period as the non-breaching party may authorize in writing) after receipt of written notice thereof if the material breach is capable of
cure and has not been cured. Waiver of a particular material breach shall not imply waiver of any other material breach. Notwithstanding the foregoing, Contractor only may terminate this Agreement or a particular Task Order in the event that the
Company fails to pay Contractor undisputed amounts under this Agreement or a particular Task Order for an extended period of time. Each party agrees to continue performing its/his obligations under this Agreement while any dispute is being resolved
except to the extent the issue in dispute precludes performance (dispute over payment shall not be deemed to preclude performance). 

11.3 Termination for Convenience. The Company may terminate this Agreement at any time for convenience and without cause. Exercise
of this right must be accomplished by giving Contractor prior written notice designating the termination date (which termination date shall not be less than five (5) days following such notice) and by paying Contractor fees due through the date
of termination as provided in Section 5.1 above. In the event that a purported termination for cause by the Company under Section 11.2 above is determined by a competent authority not to be properly a termination for cause, then such
termination by the Company shall be deemed to be a termination for convenience under this Section 11.3. 
 11.4 Task
Orders. Upon written notice to Contract, the Company may terminate any particular Task Order. The termination of any particular Task Order shall not affect the parties’ respective duties and obligations under any other Task Order(s) then in
effect. 

 12. GENERAL 

12.1 Assignment. This Agreement shall be binding on the parties hereto and their respective successors and assigns. Neither
party may, or shall have the power to, assign this Agreement without prior written consent of the other, except that the Company may assign its rights and obligations under this Agreement without approval of Contractor to an entity that acquires all
or substantially all of the assets of the Company or to any subsidiary or affiliate or successor in a merger or acquisition of the Company; provided that in no event shall such assignment relieve the Company of its obligations under this Agreement.

 12.2 Force Majeure. In the event performance of this Agreement or a particular Task Order is prevented or interfered
with by reason of acts of God, fires, floods, epidemic, strikes, or any other circumstances beyond the reasonable control and without the fault or negligence of the party affected, the party so affected, upon giving prompt notice to the other party
of the circumstances causing its delay or failure to perform and of its plans and efforts to implement a work-around solution, shall be excused from such performance on a day-to-day basis to the extent of such prevention, restriction or interference
(and the other party shall likewise be excused from performance of its obligations on a day-to-day basis until the delay, restriction or interference has ceased), provided, however, that the party so affected shall use its reasonable efforts to
avoid or remove such causes of nonperformance and both parties shall proceed whenever such causes are removed or cease. In the event such delay shall extend for a period which substantially and adversely impacts the Services, and in no event more
than three (3) consecutive days, then the Company may terminate this Agreement without liability upon written notice to Contractor. 

12.3 Informal Dispute Resolution. The parties agree that, prior to initiating formal dispute resolution relating to any matter set
forth in this Agreement, they will attempt to resolve disputes informally by working together to promptly address problems and escalate issues within their respective companies as reasonably required. 

12.4 Notices. Any notices or communication under this Agreement and/or any Task Order shall be in writing and shall be hand
delivered or sent by registered mail return receipt requested to the party receiving such communication at the address first set forth above, or such other address as either party may in the future specify to the other party in accordance with this
notice provision. 
 12.5 Governing Law. This Agreement and related Task Order(s) shall be governed by and construed in
accordance with the laws of the Commonwealth of Virginia, without regard to its choice of law rules. The sole jurisdiction and venue for any litigation arising out of this Agreement shall be an appropriate federal or state court in Virginia.

 12.6 Entire Agreement. Except as provided below in this Section 12.6, this Agreement and each Task Order attached
hereto set forth the entire understanding and agreement of the parties as to the specific subject matter therein, and supersede all prior agreements and representations, whether written or oral, with respect to the subject matter of this Agreement,
and each Task Order attached hereto, between the parties. No modification, amendment, supplement to or waiver of this Agreement or any Task Order 

 
hereunder, or any of their provisions shall be binding upon the parties hereto unless made in writing and duly signed by both parties. Notwithstanding the foregoing, the Termination Agreement
(and the Separation Agreement referenced in the Termination Agreement) shall remain in full force and effect in accordance with their current terms and shall not be modified or amended by this Agreement. 

12.7 Counterparts. This Agreement and any future Task Order may be executed in one or more counterparts, each of which shall be
deemed to be an original, but all of which shall together constitute one and the same Agreement. 
 12.8 No Waiver.
No waiver shall be effective unless in writing signed by an authorized representative of the party against whom enforcement of the waiver is sought. Neither the failure of either party to exercise any right of termination, nor the waiver of any
default or breach shall constitute a waiver of the rights granted in this Agreement with respect to any subsequent other default or breach. 

12.9 No Interference. Contractor represents to the Company that, as of the Effective Date, he is not subject to any obligation
that would prevent him from entering into this Agreement or any Task Order, and that Contractor’s offer to provide Services and the Company’s acceptance of such offer in no way causes or induces Contractor to breach any contractual
obligation to any other party. 
 12.10 Severability. In the event any one or more of the provisions of this Agreement or
of any Task Order is invalid or otherwise unenforceable, the enforceability of remaining provisions shall be unimpaired. 

12.11 Publicity. Contractor agrees that he will not refer to the existence of this Agreement or any Task Order in press releases,
advertising or materials distributed to prospective customers without the prior written consent of the Company, in each instance, which consent may be withheld in its sole discretion. The Company shall be entitled to reference this Agreement in any
public filings or press releases it makes. 
 14.12 Remedies. The rights and remedies of the Company as set forth in this
Agreement are not exclusive and are in addition to any other rights and remedies available to it at law or in equity. 
 14.13
Survival. Any provision of this Agreement which contemplates performance subsequent to any termination or expiration of this Agreement shall survive any termination or expiration of this Agreement and continue in full force and effect.

 14.14 Headings. The section headings in this Agreement are intended for reference purposes only and shall in no
way be construed to modify or restrict any of the terms or provisions of this Agreement. 
 IN WITNESS WHEREOF, the parties hereto have executed
this Agreement as of the date first above written.
