ARTICLE 4
TERMS OF EMPLOYMENT
The Executive’s employment shall commence and this Agreement shall be effective
as of the Effective Date and shall continue for a term of three (3) years
thereafter, unless earlier terminated as provided in Article 6 of this Agreement
(the “Initial Term”). The Initial Term of this Agreement shall automatically
renew for successive one (1) year periods (each, a “Renewal Term” and together
with the Initial Term, the “Term”) unless the Company or the Executive has given
written notice to the other of its intent not to renew this Agreement (a
“Non-Renewal Notice”) at least 60 days prior to the expiration of the Initial
Term or any Renewal Term, as the case may be. During any Renewal Term, the
terms, conditions and provisions set forth in this Agreement shall remain in
effect unless modified in accordance with Section 9.7.

ARTICLE 5
COMPENSATION AND BENEFITS

5.1.    Base Salary. The Company agrees to pay the Executive a base salary at an
annual rate equal to $750,000. The Executive will be entitled to annual review
of his base salary and to such increases, if any, as may be determined from time
to time by the Company. The Executive’s Base Salary will be payable as earned in
accordance with the Company’s customary payroll practice and shall be subject to
customary withholding. During the Term, the Company shall not reduce the
Executive’s salary below the Base Salary.

5.2.    Annual Bonus.

(i)
In addition to the Base Salary, with respect to each full fiscal year during the
Term, the Executive shall be eligible to earn an annual cash bonus award (a
"Bonus") that is up to 100% of his annual salary based on the achievement of
objectives set by the Company. For the year 2017, the Executive shall receive a
prorated Bonus for the remainder of the fiscal year.

(ii)
For any fiscal year in which the Bonus is not subject to the deduction limit
under Section 162(m) of the Code pursuant to the transition relief provisions of
Treasury Regulation Section 1.162-27(f)(1) (the “Transition Period”), the full
estimated Bonus (less applicable withholding taxes) shall be paid no later than
December 31 of the fiscal year to which such Bonus relates based on estimated
Consolidated EBITDA for such fiscal year (the “Estimated Bonus”); provided that,
if ARAH Group’s Consolidated EBITDA, as reflected, without duplication, in the
audited financial statements of the ARAH Group for such fiscal year differs from
the ARAH Group’s estimated Consolidated EBITDA for such fiscal year, as
reflected in the unaudited, internal financial statements used to determine the
Estimated Bonus, then the Bonus shall be recalculated by the Board, and the
Company or the Executive, as the case may be, shall pay to the other, within 30
days of such determination, any amounts that are required to reflect the actual
amount of the Bonus for such fiscal year, based upon the ARAH Group’s
Consolidated EBITDA, as reflected in the audited financial statements of the
ARAH Group. Following the Transition Period, the Bonus (less applicable
withholding taxes) shall be paid to Executive at the same time as bonuses are
generally payable to other senior executives of the Company, but in no event
later than two and one-half months following the close of the fiscal year to
which the Bonus relates.

2

--------------------------------------------------------------------------------

5.3.    Sign On Bonus.

(a)
Subject to final approval by the Board, on or about October 26, 2017, the
Company shall grant to Executive an award of Restricted Stock Units (the
“Initial Sign-On RSUs”) and options to purchase shares of Common Stock (the
“Initial Sign-On Options”) which shall commence vesting upon the Commencement
Date and shall vest in equal annual installments, on the anniversary date of the
Commencement Date, over three (3) years thereafter, subject to the Executive’s
continuing employment with the Company as of each such vesting date. The number
of Initial Sign-On RSUs shall be determined by dividing (i) $320,833 by (ii) the
closing trading price per share of the Company’s common stock as of the date of
grant. The number of Initial Sign-On Options shall be (a) determined by dividing
(i) $320,833 by (ii) the per share Black-Scholes value of the option, determined
as of the date of grant based upon the closing trading price per share of the
Company’s common stock as of the date of grant and such other variables as
determined by the Company in a manner consistent with the Company’s financial
reporting, which determination shall be final and dispositive. The per share
exercise price of the Initial Sign-On Options shall be equal to the per share
closing price of the Company’s common stock on the date of grant.

(b)
The Initial Sign-On RSUs and Initial Sign-On Options, shall otherwise be subject
to the terms and conditions of the Company’s 2016 Omnibus Incentive Plan, as may
be amended, restated or supplemented from time to time (the “Plan”), a copy of
which has been provided to the Executive.

5.4.    Equity Awards.

It is anticipated that, subject to final approval by the Board, the Executive
shall be granted or allocated following the completion of each year during the
term of this Agreement, commencing on or about March of 2018, additional equity
compensation in a combination of fifty percent (50%) stock options and fifty
percent (50%) restricted stock units (or such other securities/instruments that
the Compensation Committee of the Board of Directors (“Committee”) deems
appropriate) valuing a total of One Million One Hundred Thousand Dollars
($1,100,000) (“Awarded Securities”) as part of the long-term incentive
compensation approved annually by the Committee (each such grant or allocation
of additional equity compensation, an “Annual Equity Award”). Each Annual Equity
Award shall be granted, if at all, pursuant to the Plan. Other than as stated in
this paragraph, an Annual Equity Award in respect of any fiscal year shall have
terms and conditions substantially identical (and in any event no less favorable
in any respect) to those applicable to an Annual Equity Award generally granted
to the Company’s other senior executives in respect of the same fiscal year.

5.5    Relocation. The Company shall provide Executive with relocation
assistance in two forms - temporary relocation and permanent relocation, both
intended to be non-compensable to him as provided below.

(a)
The Company will pay up to $5,000 per month for rental and other amenities for
the Executive a furnished residence in Massachusetts, for the period until he
purchases and moves into a home in Massachusetts, this period temporary
assistance not to exceed nine (9) months (the “Temporary Relocation Allowance”).
This residence would be maintained for the Company’s convenience and business
needs of the Company so that Executive is in a position to more fully devote
himself to his position with the Company, during his early months of transition
with the Company and not be diverted to seeking a permanent residence during
that time.

3

--------------------------------------------------------------------------------

(b)
The Company will establish for the Executive an arrangement to pay or reimburse
the Executive up to $100,000 for moving and relocation assistance for a
permanent move from Georgia to Massachusetts, with the arrangements structured
by the Company so that amounts paid under the arrangement are treated as paid
under an “accountable plan”, under IRC Section 62(c) (the “Permanent Relocation
Allowance”). It is the intention of the parties that amounts treated as paid
under an accountable plan shall be excluded from the Executive's gross income,
and will be reported as wages or other compensation on the Executive's Form W-2,
and are exempt from the withholding and payment of employment taxes (Federal
Insurance Contributions Act (FICA), Federal Unemployment Tax Act (FUTA),
Railroad Retirement Tax Act (RRTA), Railroad Unemployment Repayment Tax (RURT),
and income tax.) Moving and relocation expenses include without limitation the
cost of packing, crating, and transporting household goods and personal effects
and those of the members of the Executive’s household from his former home to
his new home, costs of connecting or disconnecting utilities required because
Executive is moving his household goods, appliances, or personal effects, cost
of shipping your car and his household pets to his new home.

 
(c)
In the event there occurs a Resignation without Cause or a Termination for
Cause, in either case, prior to the first anniversary of the Commencement Date,
Executive shall promptly repay to the Company in cash a pro-rated portion of the
Permanent Relocation Allowance (not to exceed the amount received by Executive)
equal to the product of (x) $100,000 multiplied by (y) a fraction, the numerator
of which is 365 minus the number of days elapsed between the Commencement Date
and the applicable termination date and the denominator of which is 365.

5.6    Additional Benefits. In addition to the benefits and entitlements
otherwise set forth herein, the Executive will be eligible to participate in the
Company's benefit plans of general application as they may be established and
modified from time to time. The Executive shall be entitled each calendar year
to (i) reasonable holidays and illness days in accordance with the Company's
policies as may be established and modified from time to time and (ii)
reasonable paid vacation; provided that the Executive shall schedule the timing
and duration of vacations in a reasonable manner taking into account the needs
of the business of the ARAH Group.

5.7.    Expenses. The Company will reimburse the Executive for all reasonable
and necessary expenses incurred by the Executive in connection with the business
of the ARAH Group ("Expenses"), provided that such expense reimbursements are in
accordance with applicable policies of the Company in effect from time to time
and are properly documented and accounted.

5.8    Aircraft Travel. The Executive shall be provided, at the expense of the
Company, with limited use of the Company’s private aircraft, subject to
availability, for personal travel not to exceed ten (10) total hours per fiscal
year, within North America, subject to pro-ration for any partial fiscal year.
The Executive shall be solely responsible for any taxable income recognized by
him in connection with the personal use of private aircraft and shall not be
entitled to any tax gross up payments or other reimbursement from the Company in
connection therewith. Any additional hours of flight time will be charged to the
Executive at the actual out of pocket cost incurred by the Company.

5.9    Automobile Allowance. The Executive shall also be entitled to an
automobile for use during the Term of this Agreement and the Company shall pay
all expenses (including insurance, taxes and fuel) in connection therewith;
provided that, the aggregate expenditure by the Company pursuant to this
sentence for any fiscal year shall not exceed $12,000 plus all costs for
insurance and fuel.

--------------------------------------------------------------------------------

5.10     Continuing Medical Education. The Company and Executive mutually agree
as to the importance of Executive maintaining his skills through continuing
education and training, including, without limitation, all required board of
internal medicine and/or nephrology certifications. As such, the Company agrees
that during each year of this Agreement, Executive shall be entitled to such
reasonable time to accommodate required continuing medical education and board
certification leave (“CME Leave”) which shall not count against any vacation or
other paid time off benefit. All such CME Leave shall be taken only at times
approved by Employer, which approval shall not be unreasonably withheld or
delayed. The Company shall pay directly, or reimburse the Executive for, all
professional dues and meetings, licenses, technical/medical industry journals
incurred in connection with maintaining his skills and position in the
profession and industry.
5.11. Insurance; Indemnification. Throughout the Term of this Agreement and for
a period of 12 months following the effective date of the Executive’s
termination from the Company’s employment, the Company or ARH agrees to maintain
director and officer liability insurance for the benefit of the Executive in
scope and amounts reasonably acceptable to the Board. Executive shall be
entitled to indemnification under ARH’s charter and bylaws or other

consistent with the terms applicable from time to time for members of the Board.

performance or compliance by the other of any of its obligations or agreements

hereof shall not be taken or held to be a waiver of any preceding or succeeding

any kind shall be effective or binding, unless it is in writing and is signed by
the party against whom such waiver is sought to be enforced.

9.5.    Assignment. This Agreement and all rights hereunder are personal to the
Executive and may not be transferred or assigned by the Executive at any time.

(a)     Notwithstanding anything herein to the contrary, (i) if, at the time of
the Executive's termination of employment with the Company, Executive is a
"specified Executive" as defined in Section 409A of the Internal Revenue Code of
1986, as amended (the "Code"), and the deferral of the commencement of any
payments or benefits otherwise payable hereunder as a result of such termination
of employment is necessary in order to prevent any accelerated or additional tax
under Section 409A of the Code, then the Company will defer the commencement of
the payment of any such payments or benefits hereunder (without any reduction in
such payments or benefits ultimately paid or provided to Executive) until the
date that is six months following Executive's termination of employment with the
Company (or the earliest date as is permitted under Section 409A of the Code
without any accelerated or additional tax); and (ii) if any other payments of
money or other benefits due to Executive hereunder could cause the application
of an accelerated or additional tax under Section 409A of the Code, such
payments or other benefits shall be deferred if deferral will make such payment
or other benefits compliant under Section 409A of the Code, or otherwise such
payment or other benefits shall be restructured, to the extent possible, in a
manner, determined by the Board, that is reasonably expected not to cause such
an accelerated or additional tax. Any payment or benefit delayed by reason of
the prior sentence shall be paid out or provided in a single lump sum at the end
of such required delay period in order to catch up to the original payment
schedule.

(b)     For purposes of Section 409A of the Code, each payment made under this
Agreement shall be designated as a "separate payment" within the meaning of
Section 409A of the Code, any series of installment payments under this

--------------------------------------------------------------------------------

(c)     (i) Any reimbursements by the Company to the Executive of any eligible

made by no later than the earlier of the date on which they would be paid under
the Company's normal policies and the last day of the taxable year of the
Executive following the year in which the expense was incurred.

(ii) The amount of any Taxable Reimbursements, and the value of any in-kind
benefits to be provided to the Executive, during any taxable year of the
Executive shall not affect the expenses eligible for reimbursement, or in-kind
benefits to be provided, in any other taxable year of the Executive (except for
any life-term or other aggregate limitation applicable to medical expenses).

(iii) The right to Taxable Reimbursement, or in-kind benefits, shall not be
subject to liquidation or exchange for another benefit.

(d)     Notwithstanding any other provisions of this Agreement or any other
agreement to which the Company and the Executive are parties to the contrary, in
no event shall any payment under this Agreement that constitutes "deferred

any other amount unless otherwise permitted by Section 409A of the Code.

RECITALS

WHEREAS, in consideration of the employment and/or continued employment of the
Employee and any discretionary bonus, the mutual covenants and agreements
contained herein, the sufficiency and adequacy of which Employee hereby
recognizes, and any other or further consideration which may be or has been
provided to Employee in conjunction with the execution of this Agreement; and

WHEREAS, execution of this Agreement by Employee is an express condition of
Employee's employment and/or continued employment by Employer;

THE PARTIES HEREBY AGREE AS FOLLOWS:

1.1General. The Employee acknowledges that in the course of the Employee's
employment with ARA the Employee has become familiar with trade secrets and
other confidential information concerning ARA and its subsidiaries, that the
Employee's services were of special, unique and extraordinary value to ARA and
its affiliates, and that but for Employee's employment with ARA, Employee would
not have had access to ARA's trade secrets or other confidential information.

1.2    Non-Solicitation. In further consideration of Employee's employment,
Employee agrees that for a period of twelve (12) months following the
termination of Employee's relationship with the Company and the expiration of
any paid-time-off ("PTO") or severance period(s) (the "Nonsolicitation Period"),
the Employee shall not (i) solicit any of ARA's employees to work for any
competing dialysis facility/company, (ii) hire any of ARA's employees to work
(as an employee or an independent contractor) for any competing dialysis
facility/company, (iii) take any action that may reasonably result in any of
ARA's employees going to work (as an employee or an independent contractor) for
any competing dialysis facility/company, (iv) induce any patient or customer of
ARA, either individually or collectively, to patronize any competing dialysis
facility/company; (v) request or advise any patient, customer, or supplier of

into any contract the purpose or result of which would benefit Employee if any
patient or customer of ARA were to withdraw, curtail, or cancel such person's
business with ARA; (vii) solicit, induce, or encourage any physician (or former
physician) affiliated with ARA or induce or encourage any other person under
contract with ARA to curtail or terminated such person's affiliation or
contractual relationship with ARA; (viii) disclose to any Person the names or
addresses of any patient or customer of ARA or of any physician (or former
physician) affiliated with ARA; or (ix) disparage ARA or any of its agents,

14

--------------------------------------------------------------------------------

1.3    Non-Competition. In further consideration of his/her employment, Employee
agrees that he/she shall not compete with the Company during his/her employment
and for a period of six (6) months following the termination of Employee's
relationship with the Company and the expiration of any paid-time-off("PTO") or
severance period(s), irrespective of the reason or absence of reason for such
termination. For the purposes of this Section 1.3, "compete" shall mean working
or serving in any capacity in which Employee would engage in similar work or
activities as Employee did for the Company or would be in a position to utilize
Employee's knowledge and familiarity with the Company's customer base, policies,
pricing or manner of doing business, including but not limited to working or
serving as a director, officer, employee, consultant, agent, representative,
investor, or in any other capacity, with or without compensation on behalf of
one or more entities which engage in a competing dialysis facility/company,
provided, however, that nothing contained in this Agreement shall prevent
Employee from holding for investment up to 1% of the combined voting power of
the outstanding stock of a publicly-held company. Employee agrees that the
restrictions described in this section shall apply regardless of any changes in
Employee's position, duties, responsibilities or compensation during his/her
employment. Employee expressly agrees that the markets served by the Company and
their affiliates and/or subsidiaries extend nationally and are not dependent on
the geographic location of the personnel or the businesses by which they are
employed and that the restrictions set forth in this Section 1.3 have been
designed to be reasonable and are no greater than are required for the
protection of the Company and its subsidiaries and affiliates.

1.4    Confidentiality. "Confidential Information" means (a) all information
acquired by Employee from ARA, its employees, its suppliers or customers, its
agents or consultants, or others, during Employee's relationship with ARA, that
relates to the present or potential businesses, products or services and
operations or processes of ARA, as well as any other information as may be
designated by ARA as confidential or that a reasonable person would understand
from the circumstances of the disclosure to be confidential. Employee
acknowledges and agrees that: (i) in the course of employment by the Company, it
will or may be necessary for Employee to create, use, or have access to
information and materials that concern ARA's business; (ii) all Confidential
Information are the property of ARA; (iii) the use, misappropriation, or
disclosure of any Confidential Information would constitute a breach of trust
and could cause serious and irreparable injury to ARA; and (iv) it is essential
to the protection of ARA's goodwill and maintenance of ARA's competitive
position that all Confidential Information be kept confidential and that
Employee not disclose any Confidential Information to others or use Confidential
Information to Employee's own advantage or the advantage of others.

1.5    Compliance and Acknowledgement. To enable the Company to monitor
compliance with the non-competition, non-solicitation, and confidentiality
obligations imposed by this Agreement, Employee further agrees to inform in
writing the Company's Chief Executive Officer, Joseph Carlucci, of the identity
of Employee's subsequent employer(s) and prospective job title(s) and
responsibilities prior to beginning employment. Employee agrees that this notice
requirement shall remain in effect for one (1) year following the termination of
Employee's employment at the Company. Employee acknowledges and agrees that the
covenants in Sections 1.2, 1.3, 1.4 have unique, substantial and immeasurable
value to the Company, that Employee has sufficient skills to provide a
livelihood for Employee while this covenant remains in force, and that these
covenant will not interfere with Employee's ability to work consistent with
Employee's experience, training, and education.

(b)Not Employment Contract. The Employee acknowledges that this Agreement does
not constitute a contract of employment and does not guarantee that the Company
or any of its subsidiaries will continue his/her employment for any period of
time or otherwise change the at­ will nature of his/her employment.

(c)Interpretation. If any restriction set forth in herein is found by any court
of competent jurisdiction to be invalid, illegal, or unenforceable, it shall be
modified to the minimum extent necessary to render the modified restriction
valid, legal and enforceable. The parties intend that the non-competition and
non-solicitation provisions contained in this Agreement shall be deemed to be a
series of separate covenants, one for each and every county of each and every
state of the United States of America and each and every political subdivision
of each and every country outside the United States of America where this
provision is intended to be effective.

(d)Severability. The invalidity or unenforceability of any provision of this
Agreement shall not

--------------------------------------------------------------------------------

affect the validity or enforceability of any other provision of this Agreement.

(e)Waiver of Rights. No delay or omission by the Company in exercising any right
under this Agreement will operate as a waiver of that or any other right. A
waiver or consent given by the Company on any one occasion is effective only in
that instance and will not be construed as a bar to or waiver of any right on
any other occasion.

(f)Equitable Remedies. The restrictions contained in this Agreement are
necessary for the protection of the business and goodwill of the Company and its
subsidiaries and are considered by the Employee to be reasonable for such
purpose. The Employee agrees that any breach of this Agreement is likely to
cause the Company substantial and irrevocable damage and therefore, in the event
of any such breach, the Employe agrees that the Company, in addition to such
other remedies which may be available, shall be entitled to specific performance
and other injunctive relief.

(g)Governing Law. This Agreement shall be governed by and construed in
accordance with the laws of the Commonwealth of Massachusetts. Any action, suit,
or other legal proceeding which is commenced to resolve any matter arising under
or relating to any provision of this Agreement shall be commenced only in a
court within the Commonwealth of Massachusetts (or, if appropriate, a federal
court located within Massachusetts), and the Company and the Employee each
consents to the jurisdiction of such a court.

THE EMPLOYEE ACKNOWLEDGES THAT HE/SHE HAS CAREFULLY READ THIS AGREEMENT AND
UNDERSTANDS AND AGREES TO ALL OF THE PROVISIONS IN THIS AGREEMENT.

IN WITNESS WHEREOF, the parties hereto have executed this Agreement as of the
date first above written.
