Exhibit 10.18

Employee Stock Option Agreement
(Matching Options and Position 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.  If there is any inconsistency between this Agreement and the terms of the Plan, the terms of the Plan shall govern.

(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.  Except as otherwise provided in Section 6(a) or Section 2(b) of this Agreement, the Options shall become vested in five equal annual installments, with the first installment becoming vested on December 31, 2011, and the subsequent installments becoming vested on December 31 of each of the four subsequent calendar years; provided that if the Employee’s employment with the Company is terminated in a Special Termination (i.e., by reason of the Employee’s death or Disability), any Options held by the Employee shall immediately vest as of the effective date of such Special Termination.

(b)                Discretionary Acceleration.  The Board, in its sole discretion, may accelerate the vesting or exercisability of all or a portion of the Options, at any time and from time to time.

(c)                 Exercise.  Once vested in accordance with the provisions of this Agreement, 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.

(d)                No Other Accelerated Vesting.  The vesting and exercisability provisions set forth in this Section 2 or in Section 6, or expressly set forth in the Plan, shall be the exclusive vesting and exercisability provisions applicable to the Options and shall supersede any other provisions relating to vesting and exercisability, unless such other such provision expressly refers to the Plan by name and this Agreement by name and date.

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 tenth anniversary of the Grant Date (the “Normal Termination Date”), if not exercised prior to such date.

(b)                Early Termination.  If the Employee’s employment with the Company terminates for any reason, any Options held by the Employee that have not vested before the effective date of such termination of employment or that do not become vested on such date in accordance with Section 2 shall terminate immediately upon such termination of employment and, if the Employee’s employment is terminated for Cause, all Options (whether or not then vested or exercisable) shall automatically terminate immediately upon such termination.  All vested Options held by the Employee following the effective date of a termination of employment 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(a), and if not exercised within such period the Options shall automatically terminate upon the expiration of such period.

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

2

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.

(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 following a termination of the Employee’s employment prior to a Public Offering in a Special Termination, by the Company without Cause or by the Employee with Good Reason, 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

3

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.  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.

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.              Change in Control

(a)                 Vesting and Cancellation.  In the event of a Change in Control, all then-outstanding unvested Options shall automatically vest in full such that all Options outstanding hereunder shall, immediately prior to the effective date of the Change in Control, be fully vested and exercisable.  Subject to Section 6(b), upon the Change in Control, all Options then outstanding 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.

(b)                Alternative Award.  Notwithstanding Section 6(a), no cancellation, termination, or settlement or other payment shall occur with respect to any Option pursuant to Section 6(a) if the Board reasonably determines prior to the Change in Control that the Employee shall receive an Alternative Award meeting the requirements of the Plan.
