RECITALS

WHEREAS, Nobilis and Athas Sellers are parties to that certain Membership Interest Purchase Agreement (the
MIPA) dated as of November 26, 2014 (the Closing Date), which is attached hereto as Exhibit 1, whereby Subco purchased 100% of the membership interest in Athas (the Membership
Interest) from the Athas Sellers;

WHEREAS, as additional consideration for the purchase of the
Membership Interest, the Athas Sellers are currently owed, in the aggregate, 4,666,667 shares of Nobilis common stock, of which half was to be paid to the Athas Sellers on the first anniversary of the MIPAs closing date and half was to be paid
on the second anniversary of the MIPAs closing date (collectively, the Contingent Shares);

WHEREAS, pursuant to the MIPA, Nobilis sole remedy against the Athas Sellers for breach of the MIPAs representations and
warranties (other than the Fundamental Reps) is in the form of a reduction in the number of Contingent Shares issuable to the Athas Sellers pursuant to Section 2.4 and Section 2.5 of the MIPA;

WHEREAS, Nobilis believes it is entitled to indemnity from the Athas Sellers, pursuant to Article XI of the MIPA, for
certain losses incurred by Nobilis related to the matter styled RIVERVIEW HEALTH INSTITUTE LLC vs NORTH AMERICAN LASERSCOPIC SPINE INSTITUTE LLC, Civil Action Number 2012CV08393 in the Common Pleas Court of Montgomery County, Ohio, (the
RHI Litigation), and that it will likely be entitled to indemnity for certain expenses and other losses likely to be incurred as the result of certain claims and causes of action asserted against North American Laserscopic
Spine Institute, LLC, which are listed on the attached Schedule 1 (the NALSI Litigation);

WHEREAS, Nobilis also believes that it is or may be entitled to recover from the Athas Sellers independently of the MIPA expenses borne by
Athas and Nobilis related to or arising out of the NALSI Litigation, for which the Athas Sellers should have been liable and which total, in



---

the aggregate, One Million Seven Hundred Thousand Dollars ($1,700,000.00) (the NALSI Expenses), and Nobilis believes that it will be entitled to collect from the Athas
Sellers, personally, Eight Hundred Fifty Thousand Dollars ($850,000.00) which represents the principal balance of the outstanding promissory note made by NALSI in favor of Athas (the NALSI Note) to cover certain expenses
related to NALSI, all of which the Athas Sellers have contested;

WHEREAS, Nobilis has asserted, and the Athas Sellers have
contested, that they would equally share in the expenses incurred by Nobilis and Athas as the result of the matter styled ELITE AMBULATORY SURGERY CENTERS LLC vs. ATHAS HEALTH LLC, Civil Action Number 201514396 in the Harris County, Texas, Superior
Court (the Elite Litigation);

WHEREAS, the Athas Sellers have asserted, and
Nobilis has contested, that the Lock Up Period (as defined therein) in the Registration Rights Agreement by and among Parent and the Athas Sellers dated as of the Closing Date (the Registration Rights Agreement) was
terminated as the result of Parents private placement that closed on May 13, 2015, and that the Athas Sellers are now entitled to the lifting of the Lock-Up on the Closing Shares (the Lock-Up Claims) pursuant to
Section 3.4(d) of the Registration Rights Agreement;

WHEREAS, the matters described in these recitals
are the hereinafter referred to as the Disputes;

WHEREAS, each Party denies all of the claims
alleged against it related to or arising out of the Disputes; and

WHEREAS, in order to avoid further time, expense and uncertainties of
litigation, the Parties desire to settle and resolve their differences in accordance with the terms and conditions set forth herein.

NOW,
THEREFORE, in consideration of the respective promises and the Consideration of the Parties set forth herein, the Parties hereby agree to compromise and settle all disputes between them relating to the matters made the basis of the Disputes, or
