ITEM 6. CONTRACTS, ARRANGEMENTS, UNDERSTANDINGS OR RELATIONSHIPS WITH RESPECT TO SECURITIES OF THE ISSUER.

The responses to Items 4 and 5 are incorporated herein by reference.

Preferred Stock Purchase Agreement

On August 31, 2017, Holdings purchased 310,000 shares of the Issuer’s 10.00% Series A Convertible Perpetual Participating Preferred Stock, par value $0.01 per share (the “Series A Preferred Stock”), from the Issuer, pursuant to the Securities Purchase Agreement, dated as of May 9, 2017, by and among Holdings and the Issuer. Holdings paid an aggregate of $310,000,000 in cash for the Series A Preferred Stock.

Each share of Series A Preferred Stock is convertible at any time, at the election of Holdings, into the number of shares of Common Stock equal to the quotient obtained by dividing (a) the Accrued Value (as defined below) of such share of Series A Preferred Stock plus any accrued but uncompounded dividend on such share by (b) the $19.00 conversion price, subject to certain anti-dilution adjustments in accordance with the terms set forth in the Certificate of Designation governing the Series A Preferred Stock (as amended from time to time, the “Series A Preferred COD”). The Series A Preferred Stock is also convertible at the election of the Issuer, if, at any time

Page 5 of 8 Pages

on or after August 31, 2019, the volume weighted average closing price of the Common Stock equals or exceeds $42.00 for at least 20 of the prior 30 trading days, subject to certain conditions, including the effectiveness of a shelf registration statement covering the resale of any Common Stock held by Holdings.

The “Accrued Value” of each share of Series A Preferred Stock is equal to the stated value of such share (initially $1,000.00) plus all compounded dividends (whether or not declared) on such Share, except to the extent such dividend was paid in cash. Each share of Series A Preferred Stock accrues dividends daily at a rate of 10% per annum. Dividends compound quarterly on March 31, June 30, September 30 and December 31 of each year and are added to the Accrued Value of such share and, therefore, the number of shares of Common Stock into which each share of Series A Preferred Stock may be converted will increase over time. In any given quarter, subject to certain conditions, the board of directors of the Issuer may declare a cash dividend in an amount up to 50% of the amount of the dividend that has accrued and accumulated during such quarter through the end of such quarter, and the amount of any quarterly dividend paid in cash will not compound on the applicable date and will not be included in the Accrued Value of the Series A Preferred Stock.

The Issuer will not be able to redeem the Series A Preferred Stock prior to August 31, 2022 and thereafter, may redeem all, but not less than all, of the Series A Preferred Stock for cash pursuant to and subject to the terms and conditions of the Series A Preferred COD at a price per share equal to the Accrued Value of each share of Series A Preferred Stock plus any accrued but uncompounded dividends on such share, multiplied by the applicable “make whole” percentage. Holdings may also cause the Issuer to redeem the shares of Series A Preferred Stock held by it upon the occurrence of certain change of control transactions of the Issuer or the Common Stock ceasing to be listed or quoted on a trading market for cash (a “Fundamental Change”) pursuant to and subject to the terms and conditions of the Series A Preferred COD. If a Fundamental Change occurs as a result of certain change of control transactions, Holdings may cause the Issuer to redeem the Series A Preferred Stock for cash at a price per share equal to the greater of (i) the Accrued Value of each share of Series A Preferred Stock plus any accrued but uncompounded dividends on such share, multiplied by the applicable “make whole” percentage, and (ii) the product of (a) the number of shares of Common Stock into which such share of Series A Preferred Stock is then convertible, multiplied by (b) the deemed purchase price per share of Common Stock resulting from such change of control event, as determined in accordance with the Series A Preferred COD. If a Fundamental Change occurs for any other reason, Holdings may cause the Issuer to redeem the shares of Series A Preferred Stock for cash at the price per share equal to the Accrued Value of each share of Series A Preferred Stock plus any accrued but uncompounded dividends on such share, multiplied by the applicable “make whole” percentage.

Pursuant to the Series A Preferred COD, on or following the date on which the Reporting Person and its affiliates cease to collectively hold fifty percent (50%) or more of the outstanding voting stock of the Issuer, the Reporting Person and its affiliates are entitled to elect two directors to the Issuer’s board of directors for as long as the Reporting Person and its affiliates hold greater than 50% of the Series A Preferred Stock acquired by the Reporting Person on August 31, 2017, and the Reporting Person and its affiliates are entitled to elect one director to the Issuer’s board of directors for as long as the Reporting Person and its affiliates hold greater than 25% of the Series A Preferred Stock acquired by the Reporting Person on August 31, 2017.

Pursuant to the Series A Preferred COD, for as long as the Reporting Person and its affiliates collectively hold greater than 50% of the Series A Preferred Stock acquired by the Reporting Person on August 31, 2017, the approval of holders of at least the majority of the then-outstanding shares of Series A Preferred Stock, voting as a separate class, will be necessary for the Issuer to: (i) amend the Series A Preferred COD, the Company’s Certificate of Incorporation or Bylaws, the Registration Rights Agreement (as defined below) and any other rights in respect of the Series A Preferred Stock, including by merger, consolidation, recapitalization or otherwise, in each case, in any manner that adversely affects the powers, preferences or rights of the shares of Series A Preferred Stock; (ii) enter into any contract that would prohibit or restrict the ability of the Issuer to perform its obligations with respect to the Series A Preferred Stock; (iii) incur indebtedness in excess of the amount of indebtedness outstanding on August 31, 2017; (iv) extend, supplement, amend, waive or otherwise modify any material provisions of the loan documents with respect to outstanding indebtedness on August 31, 2017; (v) acquire or divest the stock or assets of any person for consideration in excess of $25 million individually or $125 million in the aggregate in any given year; (vi) establish or acquire any subsidiaries outside of the United States; (vii) effect a change of control or cause the Common Stock to cease to be listed on a national securities exchange; (viii) effect any bankruptcy or liquidation event of the Issuer or its subsidiaries; (ix) declare or pay any dividends other than dividends on the Series A Preferred Stock; (x) authorize, create or issue any capital stock of the Issuer or its subsidiaries other than stock that is junior to the Series A Preferred Stock or pursuant to any management plan; (xi) reclassify, alter or amend any existing security of the Issuer in a way that would cause it to rank senior to or pari passu with the Series A Preferred Stock; or (xii) enter into or effect any transaction involving the recapitalization, reorganization, reclassification, repurchase, redemption, exchange or other acquisition of any equity securities of the Issuer or its subsidiaries (other than repurchases or redemptions by wholly owned subsidiaries or from employees).

The designations, powers, rights and preferences of the Series A Preferred Stock are governed by the Series A Preferred COD, which was filed as Exhibit 3.3 to the Issuer’s Current Report on Form 8-K filed with the SEC on September 1, 2017.

Common Stock Purchase Agreement

On August 31, 2017, Holdings purchased 26,455,651 shares of Common Stock from H.I.G. Surgery Centers, LLC (“HIG”) pursuant to the Stock Purchase Agreement, dated as of May 9, 2017, by and among Holdings, the Issuer, H.I.G. Bayside Debt & LBO Fund II L.P. and HIG (the “Common Stock Purchase Agreement”). Holdings paid an aggregate of $502,657,369 in cash for the Common Stock acquired pursuant to the Common Stock Purchase Agreement. Pursuant to the Common Stock Purchase Agreement, Holdings has agreed that it will not transfer any of the Series A Preferred Stock held by it until 90 days after the closing of the acquisition of the Series A Preferred Stock on August 31, 2017 without the consent of the Issuer, which consent may not be unreasonably withheld, conditioned or denied.

Pursuant to the Common Stock Purchase Agreement, each of HIG and the Issuer agreed to take all required action to appoint two directors designated by Holdings to the Issuer’s board of directors. Christopher R. Gordon and T. Devin O’Reilly were designated by Holdings pursuant to the Common Stock Purchase Agreement, and their appointments to the Issuer’s board of directors became effective on August 31, 2017 upon the closing of Holdings’ acquisition of the Series A Preferred Stock.

Registration Rights Agreement

On August 31, 2017, the Issuer entered into an Amended and Restated Registration Rights Agreement (the “Registration Rights Agreement”) with Holdings and certain other stockholders of the Issuer. Pursuant to the Registration Rights Agreement, the Issuer will file a registration statement for a public offering of Common Stock, upon the request of Holdings or certain of its affiliates, and will use commercially reasonable efforts to effect the registration of the Common Stock held by Holdings (including any Common Stock issuable upon conversion of Series A Preferred Stock), subject to certain limitations as described in the Registration Rights Agreement, including a minimum net aggregate offering price and a limitation on the number of registrations the Issuer will be required to effect. The Issuer has also agreed to provide “piggy back,” “short-form” and shelf registration rights with respect to the registrable shares, each as described in the Registration Rights Agreement.

This summary of the Registration Rights Agreement is qualified in its entirety by reference to the Registration Rights Agreement, which was filed as Exhibit 10.1 to the Issuer’s Current Report on Form 8-K filed with the SEC on September 1, 2017.
