Exhibit 10.17

Employee Stock Option Agreement
(Rollover Options)

This Employee Stock Option Agreement, dated as of May 25, 2011, between CDRT Holding Corporation, a Delaware corporation, and the Employee whose name appears on the signature page hereof, is being entered into pursuant to the CDRT Holding Corporation Stock Incentive Plan.  The meaning of capitalized terms may be found in Section 7.

The Company and the Employee hereby agree as follows:

Section 1.              Grant of Options

(a)                 Confirmation of Grant.  The Company hereby evidences and confirms, effective as of the date hereof, its grant to the Employee of Options to purchase the number of shares of Common Stock specified on the signature page hereof.  The Options are not intended to be incentive stock options under the Code.  This Agreement is entered into pursuant to, and the terms of the Options are subject to, the terms of the Plan and the Rollover Agreement to which the Employee and the Company are parties.  If there is any inconsistency between this Agreement and the terms of the Plan and the Rollover Agreement, the terms of the Plan and the Rollover Agreement shall govern.  As a condition to the grant of the Options, the Employee agrees that, as of the Effective Time, the definition of “Good Reason” contained in the Plan shall supersede and replace the same definition or other provision having similar effect relating to the constructive discharge of the Employee in all agreements containing such definition or provision entered into between the Employee, on the one hand, and the Company or any of its Affiliates, on the other hand, including but not limited to any employment agreement containing such definition or provision.

(b)                Option Price.  Each share covered by an Option shall have the Option Price specified on the signature page hereof.

Section 2.              Vesting and Exercisability

(a)                 Vesting.  The Options are fully vested and exercisable as of the Grant Date.

(b)                Exercise. The Options may be exercised at any time and from time to time prior to the date such Options terminate pursuant to Section 3.  Options may only be exercised with respect to whole shares of Common Stock and must be exercised in accordance with Section 4.

Section 3.              Termination of Options

(a)                 Normal Termination Date.  Unless earlier terminated pursuant to Section 3(b) or Section 6, the Options shall terminate on the termination dates set forth on the signature page of this Agreement (the “Normal Termination Date”), if not exercised prior to such date.

(b)                Early Termination.  All Options held by the Employee following the effective date of a termination of employment, other than a termination of employment for Cause, shall remain exercisable until the first to occur of (i) the 90th day following the effective date of the Employee’s termination of employment (or the 180th day in the case of a Special Termination or a Retirement), (ii) the Normal Termination Date or (iii) the cancellation of the Options pursuant to Section 6, and if not exercised within such period the Options shall automatically terminate upon the expiration of such period.

(c)                 Special Rules Applicable to Certain Terminations of Employment.

(i)         Termination for Cause.  In the event of the Employee’s termination by the Company for Cause, all Options held by the Employee shall automatically be cancelled, and, in consideration of such cancellation, the Employee shall be paid the Notional Cause Repurchase Value (less any required withholding taxes).(1)

(1)               Example:  Assume that, prior to the closing of the merger, employee E elected to roll over an option to purchase 10,000 shares of Emergency Medical Services Corporation common stock with an exercise price of $29.65 per share.  This option was converted at the closing of the merger into an option to purchase the same number of shares (i.e., 10,000) of CDRT Holding Corporation common stock with the same exercise price (i.e., $29.65).  Assume that E is fired for “Cause” in 2012 at a time when the fair market value of the CDRT Holding common stock is $100 per share.  Instead of the option being cancelled for no value, E would receive a payment of $343,500 (less withholding taxes).  This payment is intended to replicate the payment that E would have received if (1) E’s 10,000 options had been cashed out at the closing of the merger, (2) E had reinvested the cash from the cashout in shares of CDRT Holding common stock at the then-fair market value of $64 per share and (3) those shares of CDRT Holding common stock had been repurchased at the time of E’s departure at the lower of cost and fair market value (i.e. $64, as $64 is less than $100).  This formula is the “Notional Cause Repurchase Value” contained in the definitions to this Agreement.  If the fair market value at the time of E’s departure was $50, the deemed repurchase price in step 3 would be $50 and the payment to E would be $268,359 (less withholding taxes).

2

(ii)        Termination without Cause, or with Good Reason; Death; Disability.  In the event that (i) the Employee’s employment is terminated (x) by the Company without Cause, (y) by the Employee with Good Reason or (z) by reason of the Employee’s death or Disability, and (ii) one or more of the Options terminates without being exercised because the Fair Market Value of a Share equals or exceeds the applicable Option Price (such Options, the “Out-of-the-Money Options”), then the Employee shall be paid cash in an amount that is not less than the Notional Cause Repurchase Value determined as if (I) the Employee’s employment had been terminated by the Company for Cause and (II) the Out-of-the-Money Options were the only Options subject to this Agreement.  Such payment shall be made within 30 days following the date that the Options so terminate.

Section 4.              Manner of Exercise

(a)                 General.  Subject to such reasonable administrative regulations as the Board may adopt from time to time, the Employee may exercise vested Options by giving at least 15 business days prior written notice to the Secretary of the Company specifying the proposed date on which the Employee desires to exercise a vested Option (the “Exercise Date”), the number of whole shares with respect to which the Options are being exercised (the “Exercise Shares”) and the aggregate Option Price for such Exercise Shares (the “Exercise Price”); provided that following a Public Offering notice may be given within such lesser period as the Board may permit.  The Exercise Shares shall be subject to the Subscription Agreement to which the Employee is then a party, or, if the Employee is not then a party to a Subscription Agreement, the Company and the Employee shall enter into the Subscription Agreement attached to this Agreement as Exhibit A.  Except as provided in Section 4(c) or as otherwise determined by the Board, and subject to such other terms, representations and warranties as may be provided for in the Subscription Agreement, (i) on or before the Exercise Date the Employee shall deliver to the Company full payment for the Exercise Shares in United States dollars in cash, or cash equivalents satisfactory to the Company, in an amount equal to the Exercise Price plus any required withholding taxes or other similar taxes, charges or fees and (ii) the Company shall register the issuance of the Exercise Shares on its records (or direct such issuance to be registered by the Company’s transfer agent).  The Company may require the Employee to furnish or execute such other documents as the Company shall reasonably deem necessary (i) to evidence such exercise, (ii) to determine whether registration is then required under the Securities Act or other applicable law or (iii) to comply with or satisfy the requirements of the Securities Act, applicable state or non-U.S. securities laws or any other law.

3

(b)                Restrictions on Exercise.  Notwithstanding any other provision of this Agreement, the Options may not be exercised in whole or in part, and no certificates representing Exercise Shares shall be delivered, unless (A) all requisite approvals and consents of any governmental authority of any kind shall have been secured, (B) the purchase of the Exercise Shares shall be exempt from registration under applicable U.S. federal and state securities laws, and applicable non-U.S. securities laws, or the Exercise Shares shall have been registered under such laws, and (C) all applicable U.S. federal, state and local and non-U.S. tax withholding requirements shall have been satisfied.  The Company shall use its commercially reasonable efforts to obtain any consents or approvals referred to in clause (A) of the preceding sentence, but shall otherwise have no obligations to take any steps to prevent or remove any impediment to exercise described in such sentence.

(c)                 Exercise by Net Issuance.  Except to the extent limited by any of the Financing Agreements, at the election of the Employee made upon exercise of the Options, and in lieu of the Employee being required to pay the Exercise Price plus any required withholding taxes or other similar taxes, charges or fees in United States dollars in cash or cash equivalents satisfactory to the Company, the Company shall deliver to the Employee a lesser number of shares of Common Stock having a Fair Market Value on the date of exercise equal to the amount by which the Fair Market Value of the Exercise Shares exceeds the Exercise Price plus any required withholding taxes or other similar taxes, charges or fees; provided, that the Company may elect not to permit exercise of the Options in the manner set forth in this Section 4(c) following a Public Offering if the Company makes available to the Employee a broker-assisted cashless exercise feature with respect to such exercise.  In no event shall this Section 4(c) be construed to permit net issuance in excess of the applicable portion of the exercise price and minimum required withholding taxes.

(d)                Automatic Exercise.  Notwithstanding Section 4(a), vested Options that have not been exercised prior to the applicable termination date contained in Section 3(a) or 3(b) and that are not Out-of-the-Money Options shall be exercised automatically pursuant to the procedure set forth in Section 4(c) (except to the extent limited by any of the Financing Agreements) on such termination date; provided, that (i) the Employee shall enter into the Subscription Agreement not later than five business days following the date of a request by the Company to do so and (ii) if the Employee fails to enter into the Subscription Agreement as aforesaid, the exercise of the vested Options shall be rescinded and the Employee shall be paid the Notional Cause Repurchase Value (less any required withholding taxes).

4

Section 5.              Employee’s Representations; Investment Intention.  The Employee represents and warrants that the Options have been, and any Exercise Shares will be, acquired by the Employee solely for the Employee’s own account for investment and not with a view to or for sale in connection with any distribution thereof.  The Employee represents and warrants that the Employee understands that none of the Exercise Shares may be transferred, sold, pledged, hypothecated or otherwise disposed of unless the provisions of the Subscription Agreement shall have been complied with or have expired.

Section 6.              Cancellation upon a Change in Control.  In the event of a Change in Control, all then-outstanding Options shall be canceled in exchange for a payment having a value equal to the excess, if any, of (i) the product of the Change in Control Price multiplied by the aggregate number of shares covered by all such Options immediately prior to the Change in Control over (ii) the aggregate Option Price for all such shares, to be paid as soon as reasonably practicable, but in no event later than 30 days following the Change in Control.  The foregoing notwithstanding, if mutually agreed to by the Board and the Employee, in lieu of such cancellation the Employee shall receive an Alternative Award meeting the requirements of the Plan.
