 (a) Neither the Company nor any of its Subsidiaries maintains or contributes to any employee benefit plan, pension plan, stock option, bonus or incentive plan, severance pay policy or agreement, deferred
compensation agreement, or any similar plan or agreement (an “Employee Benefit Plan”) other than the Employee Benefit Plans identified in Schedule 4.14. No other corporation, trade, or business exists which would be treated
together with the Company or any of its Subsidiaries as a single “employer” under the provisions of Section 414(b), (c), (m) or (o) of the Internal Revenue Code of 1986, as amended (the “Code”). Each
Employee Benefit Plan has been and is currently administered in compliance with its constituent documents and all reporting, disclosure and other requirements of the Employee Retirement Income Security Act of 1974, as amended
(“ERISA”), and the Code and any other Law applicable to such Employee Benefit Plan. There are no unfunded obligations of the Company or any of its Subsidiaries under any retirement, pension, profit-sharing, deferred compensation
plan or similar program, and any employee contributions withheld from payroll have been timely and fully contributed to the appropriate Employee Benefit Plan as required under applicable Law. Neither the Company nor any of its Subsidiaries is
required to make any payments or contributions to any Employee Benefit Plan pursuant to any collective bargaining agreement or any applicable labor relations Law. Neither the Company nor any of its Subsidiaries has ever maintained or contributed to
any Employee Benefit Plan providing or promising any health or other nonpension benefits to terminated employees (other than continuation coverage, at the maximum applicable premium permitted to be charged by the Company, required under
Section 4980B of the Code, or Section 601 of the ERISA). 
 (b) Schedule 4.14(b) sets forth a list of
(a) all members of the management team of the Company and DNP Canada, together with each such person’s position, date of hiring, salary and any other compensation payable to such person (including, without limitation, compensation payable
pursuant to bonus, deferred compensation or commission arrangements), and (b) each contract, commitment, arrangement, or understanding, whether oral or written, relating to the employment of, or the performance of services by, any employee,
consultant, or independent contractor. Neither the Company nor any of its Subsidiaries is delinquent in payments to any of their employees for any wages, salaries, commissions, bonuses or other direct compensation for any services performed for them
to the date hereof or amounts required to be reimbursed to such employees. The Company and each of its 

  
 12 









 
Subsidiaries are in compliance with all applicable Laws, agreements, orders, and consent decrees respecting labor, employment, immigration, fair employment practices, terms and conditions of
employment, and wages and hours. Neither the Company nor any of its Subsidiaries has any collective bargaining agreements with any of their employees. There is no labor union organizing activity pending or, to the Company’s knowledge,
threatened with respect to the Company or any of its Subsidiaries. There are no charges of employment discrimination or unfair labor practices or any strikes, slowdowns, stoppages of work, or any other concerted interference with normal operations,
pending or, to the knowledge of the Company, threatened against or involving the Company or any of its Subsidiaries. 
 (c) No
employee of the Company or any of its Subsidiaries, nor any consultant with whom the Company or any of its Subsidiaries has contracted, is in violation of any term of any employment contract, proprietary information agreement or any other agreement
relating to the right of any such individual to be employed by, or to contract with, the Company or its Subsidiaries because of the nature of the business conducted by the Company or any of its Subsidiaries; and to the Company’s knowledge, the
continued employment by the Company and its Subsidiaries of their present employees, and the performance of the contracts with their independent contractors, will not result in any such violation. Neither the Company nor any of its Subsidiaries has
received any notice alleging that any such violation has occurred. No employee of the Company or any of its Subsidiaries has been granted the right to continued employment by the Company or any of its Subsidiaries or to any material compensation
following termination of employment with the Company or its Subsidiaries. To the Company’s knowledge, no executive officer, key employee or group of employees intends to terminate his, her or their employment with the Company or its
Subsidiaries, nor does the Company or its Subsidiaries have a present intention to terminate the employment of any executive officer, key employee or group of employees. 
 4.15 Compliance with Laws; Authorizations. 
 (a) The Company and each of its
Subsidiaries have complied with each, and are not in violation of, any law, statute, regulation, rule, ordinance or order (“Laws”) to which the Company or any of its Subsidiaries or their businesses, operations, employees, assets or
properties are or have been subject. No event has occurred or circumstances exist that (with or without the passage of time or the giving of notice) may result in a violation of, conflict with or failure on the part of the Company or any of its
Subsidiaries to comply with, any Law. Neither the Company nor any of its Subsidiaries has received notice regarding any violation of, conflict with, or failure to comply with, any Law. The execution, delivery, and performance of this Agreement and
the other Closing Documents by the Company, and the sale, issuance and delivery of the Securities pursuant hereto will not, with or without the passage of time or giving of notice, result in any such violation, or be in conflict with or constitute a
default under any Law.

by this Agreement or the other Closing Documents. All Authorizations are listed in Schedule 4.15(b). No event has occurred or circumstances exist that (with or without the passage of time or the giving of notice) may result in a violation of,
conflict with, failure on the part of the Company or any of its Subsidiaries to comply with the terms of, or the revocation, withdrawal, termination, cancellation, suspension or modification of any Authorization. Neither the Company nor any of its
Subsidiaries has received notice regarding any violation of, conflict with, failure to comply with the terms of, or any revocation, withdrawal, termination, cancellation, suspension or modification of, any Authorization. Neither the Company nor any
of its Subsidiaries is in default or has received notice of any claim of default, with respect to any Authorization.

Company and its Subsidiaries may reasonably become subject, and such types and amounts of other insurance with respect to its business and properties, on both a per occurrence and an aggregate basis, as are customarily carried by persons engaged in
the same or similar businesses as the Company and its Subsidiaries. There is no default by the Company or any of its Subsidiaries, or to the knowledge of the Company, by any insurance carrier of such policies, or event which could give rise to a
default under any such policy.
