WHEREAS, in connection with the proposed business combination (the "Transaction") between the Company, the Issuer, and Agiliti Holdco, Inc. (f/k/a UHS Holdco, Inc.), a Delaware corporation ("UHS"), pursuant to an Amended and Restated Agreement and Plan of Merger, dated as of December 19, 2018, among the Company, the Issuer, UHS and the other parties thereto (as may be amended and/or restated, the "Transaction Agreement"), the Company is seeking commitments from certain interested investors to purchase shares of the Company's Class A common stock, par value $0.0001 per share (the "Class A Common Stock"), for a purchase price of $8.50 per share, in a private placement in which the Company expects to raise an aggregate of up to $750 million (subject to increase or decrease in the discretion of the Company) Capitalized terms used but not defined herein shall have the meaning set forth in the Transaction Agreement.

NOW, THEREFORE, the Subscriber, the Company and the Issuer agree as follows:

1. Subscription. Subject to the terms and conditions hereof, the Subscriber hereby agrees to subscribe for and purchase, and the Company hereby agrees to issue and sell to the Subscriber, upon the payment of the subscription price therefor, up to the number of shares of Class A Common Stock set forth on the signature page hereto (the "Shares") or such lesser number of shares as the Company may deem necessary, the purchase price for which, when taken together with the other Available Cash of the Company, is sufficient to make the Available Cash equal the Necessary Cash. The Company will notify the Subscriber in writing in advance of any such reduction in the Shares, and this Subscription Agreement (including the signature page hereto and the number of "Shares" hereunder) shall be deemed amended for all applicable purposes upon such notice. The Subscriber understands that pursuant to the Transaction Agreement the Shares will become shares of common stock in the Issuer.

2. Closing. The closing of the sale of Shares contemplated hereby (the "Closing") is contingent upon the substantially concurrent consummation of the Transaction. The Closing shall occur on the date of, and immediately prior to, the consummation of the Transaction. Upon (i) satisfaction of the conditions set forth in Section 3 below and (ii) written notice from (or on behalf of) the Company to the Subscriber (the "Closing Notice") that the Company reasonably expects all conditions to the closing of the Transaction to be satisfied on a date that is not less than two (2) business days from the date of the Closing Notice, the Subscriber shall deliver to the Company on or prior to the closing date specified in the Closing Notice (the "Closing Date") the subscription amount for the Shares subscribed (the "Subscription Amount") by wire transfer of United States dollars in immediately available funds to the account specified by the Company in the Closing Notice against delivery to the Subscriber of the Shares in book entry form to the Subscriber or to a custodian designated by the Subscriber, as applicable. In the event the closing of the Transaction does not occur within one (1) business day of the Closing Date, the Company shall promptly (but no later than one business day thereafter) return the

B-1

Subscription Amount to the Subscriber by wire transfer of Unites States dollars in immediately available funds to the account specified by the Subscriber, and any book entries shall be deemed cancelled.

3. Closing Conditions. The Closing by the Subscriber is also subject to the conditions (which conditions may be waived by the Subscriber) that, on the Closing Date:

(a) no suspension of the qualification of the Shares for offering or sale or trading in the United States, New York or NASDAQ or initiation or threatening of any proceedings for any of such purposes, shall have occurred other than in connection with the consummation of the Transaction;

(b) all representations and warranties of the Company and the Issuer contained in this Subscription Agreement shall be true and correct in all material respects (other than representations and warranties that are qualified as to materiality or Material Adverse Effect (as defined herein), which representations and warranties shall be true in all respects) at and as of the Closing Date, and consummation of the Closing shall constitute a reaffirmation by each of the Company and the Issuer of each of the representations, warranties and agreements of each such party contained in this Subscription Agreement as of the Closing Date, but in each case without giving effect to consummation of the Transaction;

(c) no applicable governmental authority shall have enacted, issued, promulgated, enforced or entered any judgment, order, law, rule or regulation (whether temporary, preliminary or permanent) which is then in effect and has the effect of making consummation of the transactions contemplated hereby illegal or otherwise restraining or prohibiting consummation of the transactions contemplated hereby, and no governmental authority shall have instituted or threatened in writing a proceeding seeking to impose any such restraint or prohibition;

(d) all conditions precedent to the closing of the Transaction, including the approval of the Company's shareholders, shall have been satisfied or waived, other than those conditions that, by their nature, are to be satisfied at the closing of the Transaction, but subject to the satisfaction of those conditions at such time (without any material waiver of any such conditions that would reasonably be expected to adversely affect the Subscriber except waivers to which the Subscriber consents in writing) and the Debt Financing contemplated by the Debt Commitment Letter (as defined in the Transaction Agreement) to be funded at Closing has been funded or will be funded at the Closing (and the Debt Financing (as defined in the Transaction Agreement) to be funded after the Closing for the purpose of the Existing Notes Refinancing (as defined in the Transaction Agreement) is not subject to any event of default or unsatisfied condition which would permit the lenders not to fund all or a portion of the Debt Financing as contemplated by the Debt Commitment Letter); and

(e) no material amendment or modification of the Transaction Agreement (as the same exists on the date hereof as provided to the Subscriber) shall have occurred that would reasonably be expected to adversely affect the Subscriber, unless the Subscriber has consented in writing to such amendment or modification.
