(on behalf of airwide solutions inc.), a Delaware corporation (the “Company”), and Carolyn Turner (“Employee”). Employee is employed by Airwide Solutions UK Limited

WHEREAS, the Company, Employee and Employee desire to set forth their understandings with respect to the matters described herein.

 NOW, THEREFORE, in consideration of the mutual covenants, representations, warranties, and agreements contained
herein, and for other good and valuable consideration, the receipt and adequacy of which are hereby acknowledged, the parties agree as follows: 
 ARTICLE I 
 RETENTION BONUS 

Definitions 
 “Without Cause” shall mean the termination of the Employee’s employment by the Employer, in which the Employer’s decision to terminate was not influenced by any of the
following factors: (i) a good faith finding by the Board of Directors of the Company or the Employer (A) of repeated or willful failure of the Employee after written notice to perform his or her reasonably assigned duties or carry out any
reasonable instruction for the Employer and/or Company, or (B) that the Employee has engaged in dishonesty, gross negligence or gross misconduct, which the Board considers may have an adverse effect on the business or affairs of the Company;
(ii) if the Board has reason to believe that the Employee has committed any criminal offence or been guilty of any dishonesty or serious misconduct in each case whether during the performance of his duties or otherwise which in the opinion of
the Board renders the Employee unfit to continue as an employee of the Employer; or (iii) a breach by the Employee of any material provision of any obligations owed to the Employer or the Company, including under the invention and
non-disclosure agreement or non-competition and non-solicitation agreement with the Company, which breach is not cured within ten days written notice thereof. 
 “Good Reason” shall exist upon (i) the relocation of the Employer’s offices such that such Employee’s daily commute is increased by at least 30 miles each way
without the written consent of the Employee; (ii) material reduction of the Employee’s annual base salary without the prior consent of the Employee (other than in connection with, and substantially proportionate to, reductions by the
Employer of the annual base salary of more than 50% of its employees); or (iii) material diminution in Employee’s duties, authority or responsibilities without the prior consent of the Employee, other than changes in duties, authority or

 responsibilities resulting from the Employee’s misconduct; provided, however,
that any reduction in duties, authority or responsibilities or reduction in the level of management to which Employee reports resulting solely from the Merger or the Buyer being acquired by and made a part of a larger entity (as, for example, when a
chief financial officer becomes an employee of the acquiring corporation following an acquisition but is not the chief financial officer of the acquiring corporation) shall not constitute Good Reason; provided, further however, that no such event or
condition shall constitute Good Reason unless (x) Employee gives the Company a written notice of termination of his employment for Good Reason not more than 90 days after the initial existence of the condition, (y) the grounds for
termination if susceptible to correction) are not corrected by the Company within 30 days of its receipt of such notice and (z) Employee’s termination of employment occurs within six months following the Company’s receipt of such
notice. 
 1.1 Retention Bonus. Upon the satisfaction of the conditions set forth herein, Employee

Total Bonus Amount shall be vested on the date that is the six (6) month anniversary of the Effective Date; (ii) a Cash Payment equaling 30% of the Total Bonus Amount shall be vested on the date that is the twelve (12) month

Period” and each vesting date, a “Vesting Date”). Each Cash Payment shall be paid in the payroll following each Vesting Date. The equivalent to Cash Payment in pounds sterling shall be determined by the
Company’s bank at the rate of exchange applying when making the Cash Payment. Employee shall only receive a Cash Payment if Employee is employed by the Employer and neither the Employee or Employer has given notice of the termination of
employment on the date such Cash Payment is to be paid; provided, however, that, if Employee is terminated by Employer Without Cause, or Employee terminates his or her employment with Employer for Good Reason, and in either case such
termination constitutes a dismissal within the meaning of Section 95 of the Employment Rights Act 1996, as amended the Company shall pay Employee all remaining Cash Payments to be paid to Employee pursuant to this Agreement within 10 days of
the effective termination date. “Good Reason” has the meaning given in this agreement. “Without Cause” has the meaning given in this agreement. 

1.2 Payment. The Cash Payments shall be paid to Employee in accordance with the Company’s normal
payroll practices.

any liability, the terms set out in this agreement have been agreed in full and final settlement of all or any claims, costs and expenses and any rights of action of any kind whatsoever whether under English, Scottish, European Union law or the laws
of any other jurisdiction the Employee has or may have against the Employer, Group Members, Mavenir, and any of its or their officers, employees, shareholders, consultants, agents or trustees of any pension scheme (in each case future, current or
