The foregoing sentence shall not apply to:

(j) the exercise or settlement of stock options (“stock options”) or restricted stock units (“restricted stock units”) granted under any stock-based employee benefit plan or other equity award plan of the Company described in the Prospectus (“benefit plan”) (excluding, for the avoidance of doubt, all manners of exercise that would involve a sale in the open market of any Securities relating to such stock options or restricted stock

units, whether to cover the applicable aggregate exercise price, withholding tax obligations or otherwise); provided that (x) the shares of Common Stock underlying such stock options or restricted stock units shall continue to be subject to the restrictions set forth in this letter agreement and (y) if the undersigned is required to file a report under Section 16(a) of the Exchange Act during the Restricted Period, the undersigned shall include a statement in such report clearly indicating that (A) the filing relates to the circumstances described in this clause (i) and (B) no shares of Common Stock or other Securities were sold by the reporting person;

For the purposes of this clause (n), a “change of control” means the consummation of any bona fide third-party tender offer, merger, consolidation or other similar transaction the result of which is that any “person” (as defined in Section 13(d)(3) of the Exchange Act), or group of persons, other than the Company or the Underwriters pursuant to the Public Offering, becomes the beneficial owner (as defined in Rules 13d-3 and 13d-5 under the Exchange Act) of securities representing 50% or more of the total voting power of the Company or the surviving entity; or

(o) the establishment or amendment of a trading plan pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Common Stock; provided that (1) such plan does not provide for the transfer of Common Stock during the Restricted Period and (2) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment or amendment, as the case may be, of such plan, such announcement or filing shall include a statement to the effect that no transfer of Common Stock may be made under such plan during the Restricted Period;

provided that:

(x) in the case of any transfer or distribution pursuant to each of the clauses (c) through (h) above, each donee, trustee, distributee or transferee shall sign and deliver a lock-up agreement to the Representatives substantially in the form of this letter agreement; and

(y) in the case of any transfer or distribution pursuant to each of the clauses (a) through (g) and (k) above, no filing under Section 16 of the Exchange Act, reporting a reduction in beneficial ownership of the Undersigned’s Securities, shall be required or shall be voluntarily made during the Restricted Period.

In addition, the undersigned agrees that, without the prior written consent of Morgan Stanley and Goldman Sachs on behalf of the Underwriters, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock or any other Security. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s shares of Common Stock except in compliance with the foregoing restrictions.

If the undersigned is an officer or director of the Company, the undersigned further agrees that the foregoing provisions shall be equally applicable to any issuer-directed Shares the undersigned may purchase in or in connection with the Public Offering.

If the undersigned is an officer or director of the Company, (i) Morgan Stanley and Goldman Sachs agree that, at least three business days before the effective date of any release or waiver of the foregoing restrictions in connection with a transfer of shares of Common Stock, Morgan Stanley and Goldman Sachs will notify the Company of the impending release or waiver, and (ii) the Company has agreed in the Underwriting Agreement to announce the impending release or waiver by press release through a major news service at least two business days before the effective date of the release or waiver. Any release or waiver granted by Morgan Stanley and

Goldman Sachs hereunder to any such officer or director shall only be effective two business days after the publication date of such press release. The provisions of this paragraph will not apply if (a) the release or waiver is effected solely to permit a transfer not for consideration and (b) the transferee has agreed in writing to be bound by the same terms described in this letter agreement to the extent and for the duration that such terms remain in effect at the time of the transfer.

The undersigned understands that the Company and the Underwriters are relying upon this letter agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this letter agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal representatives, successors and assigns. The Commencement Date referred to above means, and the Restricted Period will begin on, the date the Company first publicly files a prospectus that includes a bona fide estimate of the Public Offering price range with the Securities and Exchange Commission. This letter agreement shall automatically terminate, and the undersigned will be released from all of his, her or its obligations hereunder, upon the earliest to occur, if any, of (a) the date that the Company advises the Representatives, in writing, prior to the execution of the Underwriting Agreement, that it has determined not to proceed with the Public Offering, (b) the date that the Company withdraws the registration statement related to the Public Offering before the execution of the Underwriting Agreement, (c) if the Underwriting Agreement is executed but terminated (other than the provisions thereof that survive termination) prior to payment for and delivery of the shares of Common Stock to be sold thereunder, the date that the Underwriting Agreement is terminated or (d) August 31, 2018, if the Public Offering of the Shares has not been completed by such date.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.
