Pursuant to Section 151 of the General Corporation Law of the State of Delaware (the “DGCL”), ATI Physical Therapy, Inc., a corporation duly organized and validly existing under the DGCL (the “Issuer” or the “Company”), in accordance with the provisions of Section 103 thereof, does hereby submit the following:

WHEREAS, the Second Certificate of Incorporation of the Issuer (as amended, restated, supplemented or otherwise modified from time to time, the “Certificate of Incorporation”) authorizes the issuance of up to 1,000,000 shares of preferred stock, par value $0.0001 per share, of the Issuer (“Preferred Stock”) in one or more series; and expressly authorizes the Board of Directors of the Issuer (the “Board of Directors”), subject to limitations prescribed by Law, to provide out of the unissued shares of the Preferred Stock for one or more series of Preferred Stock and to establish from time to time the number of shares to be included in each such series and to fix the voting rights, if any, designations, powers, preferences and relative, participating, optional, special and other rights, if any, of each such series and any qualifications, limitations and restrictions thereof, as shall be stated in the resolution or resolutions adopted by the Board of Directors providing for the issuance of such series and included in a certificate of designation; and

WHEREAS, on February 23, 2022, the Board of Directors approved and adopted the following certificate of designation (this “Certificate of Designation” or this “Certificate”) for purposes of issuing shares of Preferred Stock, with a par value of $0.0001 per share, designated as a series known as “Series A Senior Preferred Stock”, with each such share having the designations, powers, preferences and relative, participating, optional, special and other rights, and the qualifications, limitations and restrictions, as set forth in this Certificate of Designation.

NOW THEREFORE, BE IT RESOLVED, that, pursuant to authority conferred upon the Board of Directors by the Certificate of Incorporation, the Board of Directors hereby provides out of the unissued shares of the Preferred Stock a series of Preferred Stock designated as “Series A Senior Preferred Stock” and authorizes for issuance 165,000 shares of the Series A Preferred Stock (as defined below), and hereby fixes the designations, powers, preferences and relative, participating, optional, special and other rights, and the qualifications, limitations and restrictions of the Series A Preferred Stock, as follows:

1. Designation.

(a) Series A Preferred Stock. A total of 165,000 shares of Preferred Stock, with a par value of $0.0001 per share, shall be designated as a series known as “Series A Senior Preferred Stock”, with each such share having an initial Stated Value of $1,000 per share (the “Series A Preferred Stock”), which Series A Preferred Stock will have the respective designations, powers, preferences and relative, participating, optional, special and other rights, and the qualifications, limitations and restrictions set forth in this Certificate of Designation.

2. Ranking; Liquidation. With respect to (a) payment of dividends, (b) distribution of assets and (c) all other liquidation, winding up, dissolution, dividend and redemption rights, the Series A Preferred Stock shall rank senior in priority of payment to all Junior Stock in any liquidation, dissolution, winding up or distribution of the Company, and junior to any existing or future secured or unsecured Indebtedness and other liabilities (including trade payables) of the Company.

3. Voting.

(a) Generally. The Holders have no voting rights with respect to the Series A Preferred Stock except as set forth in this Certificate of Designation, any other Related Agreement, or as otherwise required by law; provided, that the Holders, voting as a separate class, shall have the right to designate and elect one (1) director to serve on the Board of Directors (the “Series A Director”) until such time after the Initial Issue Date that (i) as of any applicable Fiscal Quarter end, the Company’s trailing 12-month Consolidated Adjusted EBITDA exceeds $100,000,000 or (ii) the Lead Purchaser ceases to hold at least 50.1% of the Series A Preferred Stock held by it as of the Initial Issue Date.

(b) Voting Power. At the time of any vote or consent of any of the Holders under this Certificate of Designation, any other Related Agreement or as otherwise required by law, the voting power of one share of Series A Preferred Stock, that is otherwise entitled to vote, as a percentage of the aggregate voting power of all shares of Series A Preferred Stock, shall equal the product of (i) the quotient of (A) the Liquidation Value of such share of Series A Preferred Stock as of such time divided by (B) the aggregate Liquidation Value of all shares of Series A Preferred Stock as of such time multiplied by (ii) 100.

4. Dividends.

(a) Generally. All Dividends, including Compounded Dividends, are prior to and in preference over any dividend on any Junior Stock and shall be declared and fully paid before any dividends are declared and paid, or any other distributions are made, on any Junior Stock. Except as set forth in Section 6, Dividends shall be payable to the Holders as they appear on the records of the Company on the record date for such Dividends, which, to the extent the Board of Directors determines to declare Dividends in respect of any Dividend Period, shall be the date that is 15 days prior to the applicable Dividend Payment Date, and which record date and Dividend Payment Date, to the extent so determined, shall be declared by the Board of Directors during each Dividend Period on the date that is at least 20 days prior to the Dividend Payment Date and five days prior to the record date.

(b) Dividend Calculation. From and after the Initial Issue Date, preferential cumulative dividends (“Dividends”) shall accrue on each share of Series A Preferred Stock outstanding on a daily basis in arrears at the applicable Dividend Rate then in effect. Dividends with respect to each Dividend Period shall be the sum of the dividends calculated on a daily basis during such period. The daily dividend shall be calculated as the product of (i) the Stated Value of each share of the Series A Preferred Stock outstanding as of the Dividend Payment Date for such Dividend Period, and (ii) the applicable dividend rate specified in clause (c) below (the “Dividend Rate”) for each day elapsed during such Dividend

Period divided by 360. Dividends will be due and payable quarterly in arrears on each Dividend Payment Date by either (A) a cash payment or (B) to the extent not paid in cash, automatically compounded quarterly on each Dividend Payment Date; provided that, the Company may elect to pay in cash any Dividends due and payable pursuant to the preceding clause (i) only from and after the three-year anniversary of the Initial Issue Date. On each Dividend Payment Date related to a Dividend Period for which the Company does not for any reason (including because payment of any Dividend is prohibited by law) pay in cash all Dividends that accumulated during such Dividend Period, any such unpaid Dividends shall (whether or not earned or declared) become part of the Stated Value of such share as of the applicable Dividend Payment Date (“Compounded Dividends”); provided that, unless the Board of Directors shall otherwise notify the Holders on or prior to the fifth Business Day prior to the applicable Dividend Period, any such unpaid Dividends shall (whether or not earned or declared) become part of the Stated Value of such share as of the applicable Dividend Payment Date pursuant to this Section 4.

(c) Dividend Rate. The Dividend Rate for the Series A Preferred Stock shall initially be 12.00% per annum (the “Base Dividend Rate”); provided that, with respect to any Dividends that are paid in cash on a Dividend Payment Date, the Dividend Rate shall be decreased by 1.00%; provided, further, that the Company shall inform the Holders of the intention to pay in cash prior to the start of the applicable Dividend Period.

(d) Increase to Dividend Rate. The Base Dividend Rate shall be increased by (i) 1.00% per annum on the first day following the fifth (5th) anniversary of the Initial Issue Date and each one (1)-year anniversary thereafter; and (ii) 2.00% per annum upon the occurrence of either an Event of Noncompliance or the failure by the Issuer to redeem in full for cash all of the shares of Series A Preferred Stock upon a Mandatory Redemption Event (a “Redemption Failure”); provided that, in the case of clause (ii) (A) the applicable Dividend Rate shall be so increased only while such Event of Noncompliance is continuing or during the period commencing upon the occurrence of a Redemption Failure and ending on the date on which all shares of Series A Preferred Stock are redeemed, as applicable, and, (B) thereafter, such increase shall not apply to the applicable Dividend Rate at such time as such Event of Noncompliance or Redemption Failure, as applicable, has been cured or is no longer continuing.

5. Redemption.

(a) Redemption Generally.

(i) Optional Redemption.

(A) At any time and from time to time, from and after the Initial Issue Date, to the extent not prohibited by law, the Company may elect to redeem all outstanding shares of Series A Preferred Stock, or any portion thereof in an amount not less than the Minimum Portion, in cash at a redemption price per share of Series A Preferred Stock equal to the Redemption Price on the terms and subject to the conditions set forth in this Section 5 (an “Optional Redemption”).

(B) Any election by the Company pursuant to this Section 5 shall be made by delivery to the Holders of written notice of the Company’s election to redeem, at least 10 days but no more than 60 days prior to the elected Redemption Date (each such date, an “Optional Redemption Date”), which notice shall indicate (1) the number of shares of Series A Preferred Stock being redeemed, (2) the Optional Redemption Date (or, to the extent not ascertainable at the time of such notice, a good faith estimate of the Optional Redemption Date), (3) the Redemption Price, and (4) the manner of and place designated for surrender (as set forth in Section 5(d)) of certificates representing shares of Series A

Preferred Stock to be redeemed. Any such notice may, at the Company’s discretion, be subject to one or more conditions precedent. Any redemption that is effected pursuant to this Section 5 shall be made on a pro rata basis among the Holders in proportion to the aggregate Liquidation Value of the shares of Series A Preferred Stock held by such Holders. For the avoidance of doubt, shares of Series A Preferred Stock are not redeemable at the Company’s election except pursuant to this Section 5.

(b) Redemption Price. The total price for each share of Series A Preferred Stock redeemed pursuant to Section 5(a) or Section 6 (the “Redemption Price”) shall be:

(i) with respect to any Redemption Date occurring prior to the First Call Date, an amount per share of Series A Preferred Stock equal to the Make-Whole Amount as of the Redemption Date; and

(ii) with respect to any Redemption Date occurring on or after the First Call Date, an amount per share of Series A Preferred Stock equal to (A)(x) the Liquidation Value of such share Series A Preferred Stock, multiplied by (y) the Redemption Percentage, plus (B) the aggregate accumulated and unpaid Dividends from the last Dividend Payment Date up to and including the Redemption Date.

(c) Rights After a Redemption Date. If any shares of Series A Preferred Stock are not redeemed on the applicable Redemption Date for any reason, until such shares are redeemed, all such unredeemed shares of Series A Preferred Stock shall remain outstanding and entitled to all of the designations, powers, preferences and relative, participating, optional, special and other rights, and the qualifications, limitations and restrictions of the Series A Preferred Stock set forth in this Certificate of Designation, including the right to accumulate and receive Dividends thereon as set forth in Section 4 until the date on which the Company redeems and pays in full the Redemption Price for such Series A Preferred Stock.

(d) Surrender of Certificates. The Holder of each share of Series A Preferred Stock to be redeemed pursuant to this Section 5 shall surrender the certificates representing such shares of Series A Preferred Stock to the Company, duly assigned or endorsed for transfer to the Company (or accompanied by duly executed share powers relating thereto), or, in the event the certificates are lost, stolen, missing, destroyed or mutilated, shall deliver an affidavit of loss, at the principal executive office of the Company or such other place as the Company may from time to time designate by notice to the Holders, and each surrendered certificate shall be canceled and retired and the Company shall thereafter make payment of the Redemption Price by certified check or wire transfer of immediately available funds; provided that to the extent such certificates represent a greater number of share of Series A Preferred Stock than the shares of Series A Preferred Stock actually redeemed, such Holder shall, in addition to receiving the payment of the Redemption Price for each redeemed share of Series A Preferred Stock, receive a new share certificate for the shares of Series A Preferred Stock not so redeemed.

(e) Redemption Preference. Any redemption under this Section 5 or Section 6 shall be in preference to and in priority over any dividend, distribution or redemption rights of any Junior Stock.

6. Mandatory Redemption Event.

(a) Redemption. Upon any (i) Liquidation Event, (ii) Bankruptcy Event, (iii) Change of Control Event or (iv) Forced Transaction Event (together with any Liquidation Event, Bankruptcy Event, Change of Control Event, each a “Mandatory Redemption Event”), the Company shall, to the extent not prohibited by law, redeem all of the shares of Series A Preferred Stock (such redemption, a “Mandatory

Redemption”) on the applicable Redemption Date pursuant to Section 6(b) (the “Mandatory Redemption Date”), in cash at a price per share of Series A Preferred Stock equal to the then applicable Redemption Price of such share under Section 5(b). If, on the Mandatory Redemption Date, the Company is prohibited by law from redeeming all shares of Series A Preferred Stock held by Holders, then the Company shall redeem such Series A Preferred Stock to the fullest extent not so prohibited. Any shares of Series A Preferred Stock that are not redeemed pursuant to the immediately preceding sentence shall remain outstanding and entitled to all of the designations, powers, preferences and relative, participating, optional, special and other rights, and the qualifications, limitations and restrictions of the Series A Preferred Stock set forth in this Certificate of Designation, including the right to continue to accumulate and receive Dividends thereon as set forth in Section 4 and, under such circumstances, the redemption requirements provided hereby shall be continuous, so that at any time thereafter when the Company is not prohibited by law from redeeming such shares of Series A Preferred Stock, the Company shall immediately redeem such shares of Series A Preferred Stock at a price per share of Series A Preferred Stock equal to the Redemption Price as of the Mandatory Redemption Date in accordance with Section 5 and this Section 6, together with payment of an amount equal to the product of (i) the additional accumulated and unpaid Dividends following the Mandatory Redemption Date multiplied by (ii) the Redemption Percentage applicable as of the Mandatory Redemption Date (which Redemption Percentage shall be, for the avoidance of doubt, 106.0% prior to the First Call Date).

(b) Redemption Mechanics.

(i) Prior to commencing a Mandatory Redemption, the Company shall send a notice (the “Mandatory Redemption Notice”) to each Holder, which shall state:

(A) that a Mandatory Redemption is being made and that all of such Holder’s shares of Series A Preferred Stock will be redeemed pursuant to this Section 6;

(B) (1) the Redemption Price, (2) the bank or trust company with which the aggregate Redemption Price shall be deposited on or prior to the Mandatory Redemption Date and (3) the Mandatory Redemption Date (or, to the extent not ascertainable at the time of such notice, a good faith estimate of the Mandatory Redemption Date); and

(ii) On or before any Mandatory Redemption Date, the Company shall deposit the amount of the applicable aggregate Redemption Price with a bank, trust company or exchange agent having an office in New York City irrevocably in trust for the benefit of such Holders. On the Mandatory Redemption Date, the Company shall immediately cause to be paid in cash or public securities (or a combination thereof) the applicable Redemption Price for such shares of Series A Preferred Stock to such Holders. Upon such payment in full, such shares of Series A Preferred Stock will be deemed to have been redeemed, whether or not the certificates for such shares of Series A Preferred Stock have been surrendered for redemption and canceled, and Dividends with respect to such redeemed shares of Series A Preferred Stock shall cease to accumulate and all designations, rights, preferences, powers, qualifications, restrictions and limitations of such redeemed shares of Series A Preferred Stock shall forthwith terminate.

(iii) In case fewer than all shares of Series A Preferred Stock represented by any certificate are redeemed in accordance with this Section 6, new certificates shall be issued representing the unredeemed shares of Series A Preferred Stock without cost to the Holder thereof.

(iv) The Company shall comply, to the extent applicable, with the requirements of Section 14 of the Exchange Act and any other securities laws (or rules of any exchange on which any Series A Preferred Stock are then listed) in connection with a redemption under this Section 6. To the extent there is any conflict between the notice or other timing requirements of this Section 6 and the applicable requirements of Section 14 of the Exchange Act, Section 14 of the Exchange Act shall govern.

(c) Company Efforts. The Company shall take such actions as are necessary to give effect to the provisions of Section 5 and this Section 6, including (i) in the case of a Change of Control Event, irrevocably and unconditionally offering each Holder the right to require the Company to redeem all shares of Series A Preferred Stock held by such Holder in connection with and as a condition to such Change of Control Event for a price per share of Series A Preferred Stock in cash equal to the Redemption Price and (ii) in the event the Company is prohibited by law from redeeming or is otherwise unable to redeem any shares of Series A Preferred Stock in connection with any Mandatory Redemption Event on the applicable Redemption Date, taking any action necessary or appropriate to remove promptly any impediments to its ability to redeem such shares of Series A Preferred Stock required to be so redeemed, including (A) to the extent not prohibited by law, reducing the stated capital of the Company or revaluing the assets of the Company to their fair market values under Section 154 of the DGCL if such revaluation would create surplus sufficient to make all or any portion of such Mandatory Redemption Event payment, and (B) borrowing the cash necessary to make such Mandatory Redemption Event payment to the extent it would not result in an Event of Noncompliance. In the event of any Change of Control Event in which the Company is not the continuing or surviving corporation or entity, proper provision shall be made so that such continuing or surviving corporation or entity shall agree to carry out and observe the obligations of the Company under this Certificate of Incorporation.

7. Exit Rights.

(a) If any Event of Noncompliance shall occur, then, for so long as it is continuing, the Majority Holders shall have the right, exercisable by written notice to the Company (a “Sale/Refinancing Demand”), to require the Company to commence and to engage in a process (the “Sale/Refinancing Process”) in good faith within 30 days of receipt of the Sale/Refinancing Demand to consummate a transaction (the form of which would be determined by the Board of Directors, as applicable, in good faith) in which the Net Proceeds resulting therefrom would be used to redeem the shares of Series A Preferred Stock then outstanding at the then applicable Redemption Price in accordance with the terms hereof, which transaction may include:

(i) a refinancing of the Series A Preferred Stock (a “Forced Refinancing”);

(ii) a sale of the Company and its Subsidiaries, including a sale of all or substantially all of the assets, or a sale of certain assets, lines of business or divisions, in each case, of the Company and its Subsidiaries (a “Forced Sale”); or

(iii) a transaction other than a Forced Sale or a combination of the transactions described in the foregoing clauses (i) and (ii) (together with a Forced Refinancing and Forced Sale, each a “Forced Transaction”).

The Company shall, within 30 days of receipt of the Sale/Refinancing Demand, commence a comprehensive Sale/Refinancing Process in good faith and shall thereafter use its commercially reasonable efforts, subject to applicable law, to promptly consummate a Forced Transaction in accordance with this Section 7, including (A) selecting a nationally-recognized investment banking firm experienced in similar transactions in the industry in which the Company and its Subsidiaries are engaged to assist the Company with respect to a Forced Transaction (the “Investment Bank”), (B) cooperating with the Investment Bank and the Holders in the evaluation of such Forced Transactions, (C) facilitating a customary due diligence process in respect of any such Forced Transaction, including establishing, populating and maintaining an online “data room,” (D) executing customary documents consistent with the consummation of any such Forced Transaction, (E) making required governmental filings and using commercially reasonable efforts to obtain required third party consents necessary to consummate any such Forced Transaction and (F) providing any financial or other information or audit reasonably required by the proposed acquirer’s or lender’s financing sources, and shall consult with the Supermajority Holders with respect thereto. The Company shall direct the Investment Bank to establish procedures reasonably acceptable to the Majority Holders to effect an orderly Forced Transaction with the objective of achieving the highest practicable value for the Company within a reasonable period of time. The process undertaken in furtherance of such Sale/Refinancing Demand shall be conducted under the direction of the Board of Directors of the Company.

Notwithstanding anything to the contrary set forth herein, (1) at any time prior to the consummation of a Forced Transaction, the Majority Holders may withdraw such Sale/Refinancing Demand, in their sole discretion, by providing written notice of such withdrawal to the Board of Directors (a “Withdrawal Event”), (2) no Sale/Refinancing Demand shall be exercised if Holders of less than two-thirds of the then-outstanding shares of Series A Preferred Stock (which must include the Lead Purchaser for so long as it holds at least 50.1% of the shares of Series A Preferred Stock held by it as of the Initial Issue Date) (the “Supermajority Holders”) consent to the exercise of the Sale/Refinancing Demand, and (3) a Sale/Refinancing Demand may not be exercised on more than one occasion in any twelve (12)-month period. Any shares of Series A Preferred Stock held by Advent shall be excluded from the numerator and the denominator for purposes of determining whether the Supermajority Holders is achieved.

(b) Notwithstanding anything to the contrary in this Section 7(b), if (i) the Issuer has breached its obligations set forth in Section 7(a), a Forced Transaction that results in the redemption of all of the shares of Series A Preferred Stock at the applicable Redemption Price is not consummated within twelve (12) months of the receipt by the Company of any Sale/Refinancing Demand, or less than all of the shares of Series A Preferred Stock have been redeemed at the applicable Redemption Price within twelve (12) months of the receipt by the Company of any Sale/Refinancing Demand, and (ii) a Withdrawal Event has not occurred, then, upon the consent or approval of the Supermajority Holders, as evidenced by written notice to the Company, the Holders shall have the right, by written notice to the Company, to direct a process in good faith to refinance the then outstanding shares of Series A Preferred Stock and/or consummate a Forced Sale; provided, that, in the case of a Forced Refinancing, such Forced Refinancing must be on terms reasonably acceptable to the Company and, in the case of a Forced Sale, such Forced Sale must be on terms that maximize the equity value of the Company. The Company and the Company’s Board of Directors shall (and shall request that the Company’s Affiliates) reasonably cooperate with the Supermajority Holders and the Investment Bank in such process and, subject to requirements under applicable law, the Company shall use its commercially reasonable to consummate a Forced Transaction as a result of such process.

(c) Promptly after, and no later than five Business Days following the date upon which the Company obtains actual knowledge thereof, the Company shall notify the Holders of the occurrence of any Event of Noncompliance (or any event that, if not timely cured, would constitute an Event of Noncompliance).

8. Negative Covenants.

(a) For so long as any shares of Series A Preferred Stock are outstanding, without the prior affirmative vote or written consent of the Majority Holders, the Company shall not (either directly or indirectly, including by merger, consolidation, operation of law or otherwise):

(i) issue any new Equity Interests of the Company, or cause or permit any of its the Restricted Subsidiaries to issue any new Equity Interests, ranking (with respect to dividends or distributions or entitlement on a return of capital or assets in a winding up or otherwise) pari passu with, or senior to, the Series A Preferred Stock;

(vi) enter, or cause or permit any Restricted Subsidiary to enter, into any transaction with any Affiliate of the Company or its Subsidiaries involving payment in excess of $1,000,000 in any individual transaction (it being understood that the threshold set forth above shall not apply to exempt more than $5,000,000 of payments from the application of this clause (vi)), on terms that are less favorable to the Company or such Restricted Subsidiary, as the case may be (as reasonably determined by the Company), than those that might be obtained at the time in a comparable arm’s-length transaction from a Person who is not an Affiliate, other than Permitted Affiliate Transactions;

(vii) consummate any Change of Control unless, upon consummation of such Change of Control, the Series A Preferred Stock is redeemed in full in cash in accordance with this Certificate of Designation;

(viii) consummate, or cause or permit any Restricted Subsidiary to consummate, any Asset Disposition that is not a Permitted Asset Disposition; provided, that no later than the fifth Business Day following the receipt of net proceeds in respect of any Prepayment Asset Disposition in excess of $15,000,000 in the aggregate, the Company or the applicable Restricted Subsidiary shall apply the proceeds of such sale to repay Indebtedness (other than intercompany Indebtedness); provided, further, if no Event of Noncompliance then exists, the Company and its Restricted Subsidiaries shall not be required to make a mandatory prepayment under this clause in respect of such proceeds to the extent (x) such proceeds are reinvested in the business of the Company and its Restricted Subsidiaries within 365 days following receipt thereof, or (y) the Company or any of its Restricted Subsidiaries has committed to so reinvest the such proceeds during such 365-day period

and the such proceeds are so reinvested within 180 days after the expiration of such 365-day period; it being understood that if the proceeds have not been so reinvested prior to the expiration of the applicable period, the Company or its applicable Restricted Subsidiary shall promptly repay Indebtedness with the amount of such proceeds not so reinvested as set forth above (without regard to the immediately preceding proviso);

(ix) alter the designation of any Subsidiary that is a Restricted Subsidiary as of the Initial Issue Date to be an Unrestricted Subsidiary or make any Investment in or Restricted Payment in respect of any Unrestricted Subsidiary; provided, that the Company may at any time after the Initial Issue Date designate (or redesignate) any subsidiary as an Unrestricted Subsidiary or any Unrestricted Subsidiary as a Restricted Subsidiary if: (A) immediately after giving effect to such designation, no Event of Noncompliance exists, (B) as of the date of the designation thereof, such Unrestricted Subsidiary does not own any Capital Stock in any Restricted Subsidiary (unless such Restricted Subsidiary is also designated as an Unrestricted Subsidiary) or hold any Indebtedness of or any Lien on any property of the Company or its Restricted Subsidiaries (unless the Company or such Restricted Subsidiary is permitted to incur such Indebtedness or grant such Liens in favor of such Unrestricted Subsidiary pursuant to Sections 6.01 and 6.02 of the Credit Agreement as in effect on the Initial Issue Date), (C) at the time of any designation of a Restricted Subsidiary as an Unrestricted Subsidiary, the aggregate amount of the fair market value (as determined by the Company in good faith) of the assets of such subsidiary, together with the aggregate amount of the fair market value (as determined by the Company in good faith) of all assets transferred from Restricted Subsidiaries to Unrestricted Subsidiaries prior to such time, do not exceed $10,000,000, (D) no agreements evidencing Acceptable Practice Management Arrangements and/or Management Services Agreement or Material Intellectual Property may be transferred to an Unrestricted Subsidiary and (E) at the time any Restricted Subsidiary is designated as an Unrestricted Subsidiary, such Restricted Subsidiary does not own any Material Intellectual Property or be party to an Acceptable Practice Management Arrangement. The designation of any subsidiary as an Unrestricted Subsidiary shall constitute an Investment by the Company (or its applicable Restricted Subsidiary) therein at the date of designation in an amount equal to the portion of the fair market value of the net assets of such subsidiary attributable to the Company’s (or its applicable Restricted Subsidiary’s) equity interest therein as reasonably estimated by the Company (and such designation shall only be permitted to the extent such Investment is also permitted under Section 6.06 of the Credit Agreement as in effect on the Initial Issue Date). The designation of any Unrestricted Subsidiary as a Restricted Subsidiary shall constitute the making, incurrence or granting, as applicable, at the time of designation of any then-existing Investment, Indebtedness or Lien of such subsidiary, as applicable; provided, that upon any re-designation of any Unrestricted Subsidiary as a Restricted Subsidiary, the Company shall be deemed to continue to have an Investment in the resulting Restricted Subsidiary in an amount (if positive) equal to (a) the Company’s “Investment” in such Restricted Subsidiary at the time of such re-designation, less (b) the portion of the fair market value of the net assets of such Restricted Subsidiary attributable to the Company’s equity therein at the time of such re-designation;

(x) amend, alter or repeal any provision of the Governing Documents of the Company or any of the Restricted Subsidiaries in a manner that is material and adverse to the Holders;

(xii) allow any Subsidiary of the Company that is a direct or indirect parent of Holdings or Successor Holdings (or the immediate parent of the Borrower or Successor Borrower) (each such Person, an “Intermediate Holdings”) to (A) incur any Indebtedness (other than Indebtedness incurred by Holdings pursuant to the Loan Guaranty (as defined in the Credit Agreement as in effect on the Initial Issue Date) and Guarantees by Holdings of Indebtedness or other obligations of the Borrower and/or any Restricted Subsidiary that is otherwise permitted under the Credit Agreement (as in effect on the Initial Issue Date) and this Certificate of Designation), (B) create or suffer to exist any Lien on any asset now owned or hereafter acquired by it (other than (i) Liens created by Holdings under the Collateral Documents (as defined in the Credit Agreement as in effect on the Initial Issue Date), (ii) Liens on assets of Holdings securing Indebtedness of the type permitted to be incurred under clause (A) above and (iii) other Liens on assets of Holdings of the type permitted under the Credit Agreement as in effect on the Initial Issue Date (other than in respect of Indebtedness for borrowed money)), and (C) consolidate or amalgamate with, or merge with or into, or convey, sell or otherwise transfer all or substantially all of its assets to, any Person; provided, that, so long as no Event of Noncompliance exists or would result therefrom, such Intermediate Holdings may consolidate or amalgamate with, or merge with or into, any other Person (other than the Company or any of its Subsidiaries) so long as Intermediate Holdings is the continuing or surviving Person and it is in compliance with this clause (xii); or

(xiii) conduct, transact or otherwise engage in any business or operations other than (A) the direct or indirect ownership and/or acquisition of the Equity Interests of any Subsidiary, (B) the maintenance of its legal existence, including the ability to incur fees, costs and expenses relating to such maintenance, (C) participating in tax, accounting and other administrative matters as a member of the consolidated group of the Company and its Subsidiaries, (D) the performance of its obligations under and in connection with this Certificate of Designation and any documentation governing any Series A Preferred Stock issued in compliance with this Certificate of Designation and the other agreements and transactions contemplated thereby and hereby, (E) any public offering of its or any of its direct or indirect parent’s common stock or any other issuance or registration of its Equity Interests for sale or resale not prohibited by this Certificate of Designation, including the costs, fees and expenses related thereto, (F) making any Restricted Payment or dividend or distribution or other transaction similar to a Restricted Payment and not otherwise prohibited by this Certificate of Designation, or any Investment in any Restricted Subsidiary (including, for the avoidance of doubt, the acquisition thereof), (G) incurring fees, costs and expenses relating to overhead and general operating including professional fees for legal, tax and accounting issues and paying taxes, (H) providing indemnification to officers and members of the Board of Directors, (I) activities incidental to the consummation of the Transactions, and (J) activities incidental to the businesses or activities described in clauses (A) to (I) of this clause (xiii). For so long as any Series A Preferred Stock is outstanding, the Company and each Intermediate Holdings shall own, directly or indirectly, all of the outstanding Equity Interests of the Borrower.

(b) In the event of (i) any reclassification, statutory exchange, merger, consolidation or other similar business combination of the Company with or into another Person, in each case, pursuant to which at least a majority of the common Capital Stock (but not the Series A Preferred Stock) is changed

or converted into, or exchanged for, securities or other property of another Person, (ii) any reclassification, recapitalization or reorganization of the common Capital Stock (but not the Series A Preferred Stock) into securities of another Person or (iii) the conveyance, sale, lease, assignment, transfer or other disposition of all or substantially all of the Company’s assets or other properties (taken as a whole) (a “Reorganization Event”), each share of Series A Preferred Stock outstanding immediately prior to such Reorganization Event will, without the consent of the Holders and subject to all the other terms hereof, remain outstanding unless redeemed in accordance with this Certificate of Designation in connection with such Reorganization Event; provided, that in no event will the Company enter into or effect any such Reorganization Event if it would materially and adversely affect the rights of Holders. This provision shall similarly apply to successive Reorganization Events.
