Subsidiaries on a consolidated basis, without duplication, the sum of: (a)
Consolidated Interest Charges paid or payable in cash, (b) scheduled principal

as a Eurodollar Rate Loan and ending on the date one, two, three, six months
(and subject to availability to all applicable Lenders, twelve months or less)
thereafter as selected by the Borrower in its Loan Notice; provided that:

(a)    any Interest Period that would otherwise end on a day that is not a
Business Day shall be extended to the next succeeding Business Day unless, in
the case of a Eurodollar Rate Loan, such Business Day falls in another calendar
month, in which case such Interest Period shall end on the next preceding
Business Day;

(b)    any Interest Period that begins on the last Business Day of a calendar
month (or on a day for which there is no numerically corresponding day in the
calendar month at the end of such Interest Period) shall end on the last
Business Day of the calendar month at the end of such Interest Period; and

(c)    no Interest Period shall extend beyond the Maturity Date of the Facility
under which such Loan was made.

(b)The definition of “Permitted Acquisition” in Section 1.1 of the Credit
Agreement is hereby amended by (i) deleting “and” at the end of clause (g) of
such definition; (ii) deleting the period at the end of clause (h) of such
definition and replacing it with “; and” in lieu thereof; and (iii) adding a
clause (i) at the end of such definition to read in its entirety as set forth
below:

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

“(i) with respect to any Acquisition which is closing during the 2017 fiscal
year, Required Lender approval and consent (such approval and consent not to be
unreasonably withheld or delayed).”

(c)Section 2.2(a) of the Credit Agreement is hereby amended by deleting such
section in its entirety and replacing it with the following in lieu thereof:

“(a) Each Term Loan Borrowing, each Revolving Credit Borrowing, each conversion
of Term Loans or Revolving Credit Loans from one Type to the other, and each
continuation of Eurodollar Rate Loans shall be made upon the Borrower’s
irrevocable written notice to the Administrative Agent in the form of a Loan
Notice, which notice must be received by the Administrative Agent not later than
11:00 a.m. (i) three Business Days prior to the requested date of any Borrowing
of, conversion to or continuation of Eurodollar Rate Loans or of any conversion
of Eurodollar Rate Loans to Base Rate Loans, and (ii) on the requested date of
any Borrowing of Base Rate Loans. Except as otherwise agreed by the
Administrative Agent and except in connection with any automatic conversion or
continuation provided in this Section 2.2(a), each Borrowing of, conversion to
or continuation of Eurodollar Rate Loans shall be in a principal amount of
$1,000,000 or a whole multiple of $100,000 in excess thereof. Except as provided
in Sections 2.3(c) and 2.4(c), except as otherwise agreed by the Administrative
Agent and except in connection with any automatic conversion or continuation
provided in this Section 2.2(a), each Borrowing of or conversion to Base Rate
Loans shall be in a principal amount of $1,000,000 or a whole multiple of
$100,000 in excess thereof. Each Loan Notice shall specify (i) whether the
Borrower is requesting a Term Loan Borrowing, a Revolving Credit Borrowing, a
conversion of Term Loans or Revolving Credit Loans from one Type to the other,
or a continuation of Eurodollar Rate Loans, (ii) the requested date of the
Borrowing, conversion or continuation, as the case may be (which shall be a
Business Day), (iii) the principal amount of Loans to be borrowed, converted or
continued, (iv) the Type of Loans to be borrowed or to which existing Term Loans
or Revolving Credit Loans are to be converted and (v) if applicable, the
duration of the Interest Period with respect thereto. If the Borrower fails to
specify a Type of Loan in a Loan Notice for Revolving Credit Loans or if the
Borrower fails to give a timely notice requesting a conversion or continuation
of Revolving Credit Loans, then the applicable Revolving Credit Loans shall be
made as, or converted to, Base Rate Loans. If the Borrower fails to give a
timely notice requesting a conversion or continuation of a Term Loan that is a
Eurodollar Rate Loan, then (x) if no Default has then occurred and is
continuing, the applicable Term Loan shall be continued as a Eurodollar Rate
Loan with an Interest Period of three months and (y) if a Default has then
occurred and is continuing, the applicable Term Loan shall be converted to a
Base Rate Loan. Any such automatic conversion or continuation of Eurodollar Rate
Loans referred to in either of the immediately two preceding sentences shall be
effective as of the last day of the Interest Period then in effect with respect
to the applicable Eurodollar Rate Loans. If the Borrower requests a Borrowing
of, conversion to, or continuation of Eurodollar Rate Loans in any such Loan
Notice, but fails to specify an Interest Period, it will be deemed to have
specified an Interest Period of three months. Notwithstanding anything to the
contrary herein, a Swingline Loan may not

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

be converted to a Eurodollar Rate Loan. Notwithstanding the foregoing, if the
Borrower wishes to request Eurodollar Rate Loans having an Interest Period other
than one, two, three or six months in duration as provided in the definition of
“Interest Period,” the applicable Loan Notice must be received by the
Administrative Agent not later than 11:00 a.m. four Business Days prior to the
requested date of such Borrowing, conversion or continuation, whereupon the
Administrative Agent shall give prompt notice to the applicable Lenders of such
request and determine whether the requested Interest Period is acceptable to all
of them. Not later than 11:00 a.m., three Business Days before the requested
date of such Borrowing, conversion or continuation, the Administrative Agent
shall notify the Borrower (which notice may be by telephone) whether or not the
requested Interest Period has been consented to by all the Lenders.”

(d)Section 6.1 of the Credit Agreement is hereby amended by (i) deleting “and”
at the end of clause (b); (ii) deleting the period at the end of clause (c) and
replacing it with “; and” in lieu thereof; and
(iii) adding a clause (d) to read in its entirety as set forth below:

“(d) as soon as available and in any event no later than forty-five (45) days
after the last day of each quarter end in the 2017 fiscal year, (i) a
comparison, in reasonable detail satisfactory to Administrative Agent, of the
consolidated financial performance of Parent (and its Subsidiaries) for the then
ended fiscal quarter to quarterly projections for the then ended fiscal quarter
(based on the monthly projections delivered by Borrower pursuant to clause (c)
above), together with a management discussion and analysis report, in reasonable
detail, signed by the chief financial officer or chief accounting officer of
Parent and (ii) revised projections of the Parent (and its Subsidiaries)
consolidated for the 2017 fiscal year on a quarterly basis including the actual
financial performance of Parent (and its Subsidiaries) to date, together with a
management discussion and analysis report, in reasonable detail, signed by the
chief financial officer or chief accounting officer of Parent, describing the
projected operations and financial condition of the Parent and its Subsidiaries
for such periods.”

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

(e)Section 7.11(a) of the Credit Agreement is hereby amended by deleting such
section in its entirety and replacing it with the following in lieu thereof (it
being understood that no independent reporting or testing of the Consolidated
Leverage Ratio for the fiscal quarter ended September 30, 2016 shall be required
pursuant to Section 7.11(a) of the Credit Agreement, but that any test or
measurement that requires compliance with the Consolidated Leverage Ratio then
in effect prior to the date of delivery of the financial statements for the
fiscal year ended December 31, 2016 shall utilize the September 30, 2016 level
set forth below):

December 31, 2020 and the last day of each fiscal quarter thereof
2.00 to 1.00

Notwithstanding the covenant levels set forth in above, at the election of the
Borrower given in writing to the Administrative Agent in connection with a
Material Acquisition, commencing with the fiscal quarter during which such
Material Acquisition is consummated, the Consolidated Leverage Ratio shall be
subject to a covenant adjustment (“Covenant Holiday”). If so elected, (i) the
maximum Consolidated Leverage Ratio during the Covenant Holiday shall be equal
to the applicable requirement set forth above plus 0.25, (ii) the period of each
Covenant Holiday shall last no longer than three fiscal quarters (or such
shorter period as Borrower may request), (iii) there shall be at least one
fiscal quarter between Covenant Holidays, and (iv) there shall be no more than
two Covenant Holidays during the term of this Agreement. After the period of
each Covenant

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

Holiday, the maximum permitted Consolidated Leverage Ratio shall be as set forth
in the table above.”

(f)Section 7.11(b) of the Credit Agreement is hereby amended by deleting such
section in its entirety and replacing it with the following in lieu thereof (it
being understood that no independent reporting or testing of the Consolidated
Fixed Charge Coverage Ratio for the fiscal quarter ended September 30, 2016
shall be required pursuant to Section 7.11(b) of the Credit Agreement, but that

THE SECURITIES REFERENCED HEREIN HAVE NOT BEEN REGISTERED UNDER THE SECURITIES
ACT OF 1933, AND HAVE BEEN ACQUIRED FOR INVESTMENT AND NOT WITH A VIEW TO, OR IN
CONNECTION WITH, THE SALE OR DISTRIBUTION THEREOF. NO SUCH SALE OR DISTRIBUTION
MAY BE EFFECTED WITHOUT AN EFFECTIVE REGISTRATION STATEMENT RELATED THERETO OR
AN OPINION OF COUNSEL IN A FORM SATISFACTORY TO THE COMPANY THAT SUCH
REGISTRATION IS NOT REQUIRED UNDER THE SECURITIES ACT OF 1933.
CONVERTIBLE PROMISSORY NOTE
$5,000,000    January 23, 2017
Houston, Texas, United States
For value received, Nobilis Vascular Texas, LLC, a Texas limited liability
company (the “Maker”), promises to pay to Carlos R. Hamilton III, M.D. or other
such designated payee (the “Holder”), the principal sum of Five Million Dollars
($5,000,000). Interest shall accrue from the date of this Note on the unpaid
principal amount at a simple rate equal to five percent (5%) per annum. This
Note is issued pursuant to that certain Asset Purchase Agreement dated January
6, 2017, by and among Buyer, NHC, Holder, and Sellers (the “Purchase
Agreement”). Capitalized terms not otherwise defined herein have the meaning
given them in the Purchase Agreement. This Note is subject to the following
terms and conditions.
1.Installments. Principal under this Note shall be payable in two (2) equal
installments, each of which shall be Two Million Five Hundred Thousand Dollars
($2,500,000), the first of which shall be due and payable on the first
anniversary of the date of this Note and the second of which shall be due and
payable on the second anniversary of this Note (collectively, the “Installment
Dates”). Subject to Sections 3, 4, and 7 below, interest shall accrue on this
Note and shall be due and payable on each Installment Date.
2.Final Maturity Date. The Final Maturity Date shall be the earlier of the
second Installment Date specified above or the date upon which all remaining
principal owing under this Note is paid in full.
3.Conversion Option. On the Installment Dates, the then outstanding principal
(but excluding accrued and unpaid interest under this Note) (the “Conversion
Amount”) may be converted, at the sole discretion of Maker, into such number of
shares of NHC’s Common Stock,

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

traded on the NYSE, equal to the quotient obtained by dividing the Conversion
Amount by the volume weighted average price of NHC’s Common Stock traded on the
NYSE in the trailing ten (10) trading days prior to the applicable Installment
Date. Notwithstanding the above, if NHC’s Common Stock is not at the time of
conversion listed for trading on the NYSE, if NHC has received notice from the
NYSE that NHC is not in compliance with one or more continuing listing standards
for trading on the NYSE, or if NHC has taken any action to delist the Common
Stock from the NYSE, then NHC’s right to convert under this Note shall
terminate. Moreover, Maker’s above conversion option shall not be exercisable if
an Event of Default occurs (as defined below).
4.Mechanics and Effect of Conversion. Maker shall notify the Holder in writing
at least five (5) Business Days prior to the Installment Dates as to whether
Maker will exercise the Conversion Option in Section 3 above. No fractional
shares of NHC’s Common Stock will be issued upon conversion of this Note. In
lieu of any fractional share to which the Holder would otherwise be entitled,
NHC will pay to the Holder in cash the amount of the unconverted principal
balance of this Note that would otherwise be converted into such fractional
share. Upon conversion of this Note, the Holder shall surrender this Note, duly
endorsed, at the principal offices of NHC or any transfer agent of NHC. At its
expense, NHC will, as soon as practicable thereafter, issue the number of shares
to which such Holder is entitled upon such conversion, including a check payable
to the Holder for any cash amounts payable as described herein, and shall
deliver to such Holder, at such principal office, a certificate or certificates
for the number of shares to which such Holder is entitled upon such conversion.
Upon full conversion of this Note, the Maker will be forever released from all
of its obligations and liabilities under this Note with regard to that portion
of the principal amount being converted including without limitation the
obligation to pay such portion of the principal amount. Upon conversion of the
principal amount of this Note into NHC’s Common Stock, any interest accrued on
this Note shall be immediately paid to the Holder.
5.Payment; Prepayment. All payments shall be made in lawful money of the United
States of America at such place as the Holder hereof may from time to time
designate in writing to the Maker. Payment shall be credited first to the
accrued interest then due and payable and the remainder shall be applied to
principal. Maker may prepay this Note at any time without penalty.
6.Stockholders, Officers and Directors Not Liable. In no event shall any
stockholder, officer or director of the Maker, Company, or NHC be liable for any
amounts due or payable pursuant to this Note.
7.Default; Remedies.
(a)The occurrence of any one or more of the following events with respect the
Maker shall constitute an event of default hereunder (“Event of Default”):
(i)If Maker shall fail to pay when due any payment of principal or interest on
this Note.
(ii)If, pursuant to or within the meaning of the United States Bankruptcy Code,
any other federal, state, or analogous Canadian law relating to insolvency or
relief of debtors (a “Bankruptcy Law”), the Maker shall (A) commence a voluntary
case or proceeding, (B) consent to the entry of an order for relief against it
in an involuntary case, (C) consent to the appointment of a trustee, receiver,
assignee, liquidator or similar official, (D) make an assignment for the benefit
of its creditors, or (E) admit in writing its inability to pay its debts as they
become due.
(iii)If a court of competent jurisdiction enters an order or decree under any
Bankruptcy Law that (A) is for relief against the Maker in an involuntary case,
(B) appoints a trustee, receiver, assignee, liquidator or similar official for
the Maker, or substantially all of

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

their respective properties, or (C) orders the liquidation of the Maker, and in
each case the order or decree is not dismissed within sixty (60) days.
(b)The Maker shall notify the Holder in writing no more than five (5) days after
the occurrence of any Event of Default of which the Maker has actual knowledge.
(c)Upon the occurrence of an Event of Default hereunder, the Holder may, at its
option, (i) by written notice to Maker, declare the entire unpaid principal
balance of this Note, together with all accrued interest thereon, immediately
due and payable regardless of any prior forbearance and (ii) exercise any and
all rights and remedies available to it under applicable law, including, without
limitation, the right to collect from Maker all sums due under this Note,
including, without limitation, reasonable attorneys’ fees.
8.Interest Rate Limitation. Notwithstanding anything to the contrary contained
in this Note or the Purchase Agreement, the interest paid or agreed to be paid
under this Note shall not exceed the maximum rate of non-usurious interest
permitted by applicable law (the “Maximum Rate”). If the Holder shall receive
interest in an amount that exceeds the Maximum Rate, the excess interest shall
be applied to the principal remaining owed under this Note or, if it exceeds
such unpaid principal, refunded to the Maker. In determining whether the
interest contracted for, charged, or received by the Holder exceeds the Maximum
Rate, the Holder may, to the extent permitted by applicable law, (a)
characterize any payment that is not principal as an expense, fee, or premium
rather than interest, (b) exclude voluntary prepayments and the effects thereof,
and (c) amortize, prorate, allocate, and spread in equal or unequal parts the
total amount of interest throughout the contemplated term of this Note.
9.Loss of Note. Upon receipt by Maker of evidence satisfactory to it of the
loss, theft, destruction or mutilation of this Note or any Note exchanged for
it, and indemnity satisfactory to Maker (in case of loss, theft or destruction)
or surrender and cancellation of such Note (in the case of mutilation), Maker
will make and deliver in lieu of such Note a new Note of like tenor.

from time to time, and any successor statute and all rules and regulations

governing such obligation or (B) are intended to be rolled into a refinancing or
replacement (in whole or in part) of the Senior Indebtedness (other than
obligations under a Secured Hedge Agreement) and (iii) obligations not yet due

Financing Agreement and (ii) the parties acknowledge and agree that (1) Maker’s
failure to make a payment of principal or interest when due under this Note at
any time that such payment is prohibited under the terms of any Senior

herein shall be deemed to prohibit the exercise by a Holder of all powers,
rights and remedies of such party hereunder. The parties hereby designate all
Senior Lenders, from time to time, as intended third-party beneficiaries of this
Note. Each holder of Senior Indebtedness, whether now outstanding or hereafter
created, incurred, assumed or guaranteed, shall be deemed to have acquired

Bankruptcy Code or any other applicable law.
