 ARTICLE II 

REGISTRATION RIGHTS 

SECTION 2.1 Piggyback Rights. 

(a) If at any time following expiration of the Lockup Period (or, if earlier, such time as the Demand Party exercises a demand right pursuant
to Section 2.2(a))2 the Company proposes to register Securities for public sale (whether proposed to be offered for sale by the Company or by any other Person) under the Securities Act (other
than a registration on Form S-4 or S-8, or any successor or other forms promulgated for similar purposes) in a manner which would permit registration of Registrable
Securities for sale to the public under the Securities Act, it will, at each such time following expiration of the Lockup Period (or if earlier, such time as the Demand Party exercises a demand right pursuant to Section 2.2(a)), give prompt
written notice (which notice shall specify the intended method or methods of disposition) to the Holders of its intention to do so and of such Holder’s rights under this Section 2.1. Upon the written request of any Holder made within
fifteen (15) days after the receipt of any such notice (which request shall specify the number of Registrable Securities intended to be disposed of by such Holder), the Company will use its reasonable best efforts to effect the registration
under the Securities Act of all Registrable Securities which the Holders have so requested to be registered; provided that: (i) if, at any time after giving written notice of its intention to register any Securities and prior to the
effective date of the registration statement filed in connection with such registration, the Company shall determine for any reason not to proceed with the proposed registration of the Securities to be sold by it, the Company may, at its election,
give written notice of such determination to the Holders and, thereupon, the Company shall be relieved of its obligation to register any Registrable Securities in connection with such registration (but not from its obligation to pay the Registration
Expenses incurred in connection therewith) without prejudice to the rights of the Demand Party to request that such registration be effected as a registration under Section 2.2(a); and (ii) if such registration involves an underwritten
offering, the Holders of Registrable Securities requesting to be included in the registration must, upon the written request of the Company, sell their Registrable Securities to the underwriters on the same terms and conditions as apply to the other
Securities being sold through underwriters under such registration, with, in the case of a combined primary and secondary offering, only such differences, including any with respect to representations and warranties, indemnification and liability
insurance, as may be customary or appropriate in combined primary and secondary offerings. 
 (b) Expenses. The Company will pay all
Registration Expenses in connection with each registration of Registrable Securities requested pursuant to this Section 2.1. 
 (c)
Priority in Piggyback Registrations. If a registration pursuant to this Section 2.1 involves an underwritten offering and the managing underwriter advises the Company in writing (a copy of which shall be provided to the Holders) that, in
its opinion, the number of Registrable Securities and other Securities requested to be included in such registration exceeds the number which can be sold in such offering, so as to be likely to have a material and adverse effect on the price, timing
or distribution of the Securities offered in such offering, then the Company will include in such registration: (i) first, the Securities the Company proposes to sell for its own account; and (ii) second, such number of Registrable
Securities requested to be included in such registration which, in the opinion of such managing underwriter, 
  

	2	Note to WSGR: Per early discussions on the lock-up agreement, draft contemplated that Blackstone could make a demand before the lock-up period expires to get the
Company working on an S-1 in advance of the lock-up expiration and the S-1 being filed (though an earlier filing could be made with underwriter consent). 


	


  
 -6- 








 
can be sold without having the material and adverse effect referred to above, which number of Registrable Securities shall be allocated pro rata among the Registrable Securities held by
all such requesting Holders on the basis of the relative number of Registrable Securities requested to be included in such registration by each such Holder (provided that any Securities thereby allocated to any such Holder that exceed such
Holder’s request will be reallocated among the remaining requesting Holders in like manner). Any other selling holders of the Company’s Securities (other than transferees to whom a Holder has assigned its rights under this Agreement) will
be included in an underwritten offering only with the consent of Holders holding a majority of the shares being sold in such offering. 
 (d)
Excluded Transactions. The Company shall not be obligated to effect any registration of Registrable Securities under this Section 2.1 incidental to the registration of any of its Securities in connection with: 

(i) the IPO; 

(ii) a registration statement filed to cover issuances under employee benefits plans or dividend reinvestment plans; or 

(iii) any registration statement relating solely to the acquisition or merger after the date hereof by the Company or any of
its Subsidiaries of or with any other businesses. 
 (e) Plan of Distribution, Underwriters and Counsel. If a registration pursuant to
this Section 2.1 involves an underwritten offering, the Holders of a majority of the Registrable Securities included in such underwritten offering shall have the right to (i) determine the plan of distribution, (ii) select the
investment banker or bankers and managers to administer the offering, including the lead managing underwriter (provided that such investment banker or bankers and managers shall be reasonably satisfactory to the Company), and (iii) select
counsel for the selling Holders. 
 (f) Shelf Takedowns. In connection with any shelf takedown (whether pursuant to
Section 2.2(f) or at the initiative of the Company), the Holders may exercise “piggyback” rights in the manner described in this Agreement to have included in such takedown Registrable Securities held by them that are registered on
such shelf registration statement. 
 SECTION 2.2 Demand Registration. 

(a) General. At any time, upon the written request of any Blackstone Entity (the “Demand Party”) requesting that the
Company effect the registration under the Securities Act of Registrable Securities and specifying the amount and intended method of disposition thereof (including, but not limited to, an underwritten public offering), the Company will
(i) promptly give written notice of such requested registration to the other Holders and other holders of Securities entitled to notice of such registration, if any, and (ii) as expeditiously as possible, use its reasonable best efforts to
file a registration statement to effect the registration under the Securities Act of: 

  
 -7- 








 (i) such Registrable Securities which the Company has been so requested to
register by the Demand Party in accordance with the intended method of disposition thereof; and 
 (ii) the Registrable
Securities of other Holders which the Company has been requested to register by written request given to the Company within fifteen (15) days after the giving of such written notice by the Company. 

Notwithstanding the foregoing, the Company shall not be obligated to file a registration statement relating to any registration request under this
Section 2.2(a): 
 (x) within a period of one hundred eighty (180) days (or such lesser period as the managing
underwriters in an underwritten offering may permit) after the effective date of any other registration statement relating to any registration request under this Section 2.2(a) or relating to any registration referred to in Section 2.1; or

 (y) if, in the good faith judgment of a majority of the disinterested members of the Board, the Company is in possession
of material non-public information the disclosure of which would be materially adverse to the Company and would not otherwise be required under Law, in which case the filing of the registration statement may be delayed until the earlier of the
second Business Day after such conditions shall have ceased to exist and the 60th day after receipt by the Company of the written request from a Demand Party to register Registrable Securities under this Section 2.2(a); provided that the
Company shall not effect such a delay more than two times in any twelve (12) month period. 
 (b) Form. Each registration
statement prepared at the request of a Demand Party shall be effected on such form as reasonably requested by the Demand Party, including by a shelf registration pursuant to Rule 415 under the Securities Act on a Form S-3 (or any successor rule or
form thereto) if so requested by the Demand Party and if the Company is then eligible to effect a shelf registration and use such form for such disposition. 

(c) Expenses. The Company will pay all Registration Expenses in connection with each registration of Registrable Securities requested
pursuant to this Section 2.2. 
 (d) Plan of Distribution, Underwriters and Counsel. If a requested registration pursuant to this
Section 2.2 involves an underwritten offering, the Holders of a majority of the Registrable Securities included in such underwritten offering shall have the right to (i) determine the plan of distribution, (ii) select the investment
banker or bankers and managers to administer the offering, including the lead managing underwriter (provided that such investment banker or bankers and managers shall be reasonably satisfactory to the Company) and (iii) select counsel for the
selling Holders. 
 (e) Priority in Demand Registrations. If a requested registration pursuant to this Section 2.2 involves an
underwritten offering and the managing underwriter advises the Company in writing (a copy of which shall be provided to the Holders) that, in its opinion, the number of Registrable Securities requested to be included in such registration (including


  
 -8- 








 
Securities of the Company which are not Registrable Securities) exceeds the number which can be sold in such offering, so as to be likely to have a material and adverse effect on the price,
timing or distribution of the Securities offered in such offering, then the number of such Registrable Securities to be included in such registration shall be allocated pro rata among Registrable Securities held by the Demand Party and other
parties that have requested that their Registrable Securities be sold pursuant to Section 2.1(a), if any, on the basis of the relative number of Registrable Securities requested to be included in such registration by each such Holder (provided
that any Securities thereby allocated to any such Holder that exceed such Holder’s request will be reallocated among all such remaining parties in like manner). Any other selling holders of the Company’s Securities (other than transferees
to whom a Holder has assigned its rights under this Agreement) will be included in an underwritten offering only with the consent of Holders holding a majority of the shares being sold in such offering. 

(f) Shelf Takedowns. Upon the written request of the Demand Party at any time and from time to time, the Company will facilitate in the
manner described in this Agreement a “takedown” of the Demand Party’s Registrable Securities off of an effective shelf registration statement. Upon the written request of the Demand Party, the Company will file and seek the
effectiveness of a post-effective amendment to an existing shelf registration statement in order to register up to the number of the Demand Party’s Registrable Securities previously taken down off of such shelf by the Demand Party and not yet
“reloaded” onto such shelf registration statement. 
 (g) Additional Rights. Except as expressly provided in this Agreement,
the Company shall not grant to any Person the right to request or require the Company to register any equity Securities of the Company, or any Securities convertible, exchangeable or exercisable for or into such Securities, or amend any grant of
such a right, without the prior written consent of the Holders holding a majority of the Registrable Securities subject to this Agreement. In the event the Company engages in a merger or consolidation in which the shares of Common Stock are
converted into Securities of another company, appropriate arrangements will be made so that the registration rights provided under this Agreement continue to be provided to Holders by the issuer of such Securities. To the extent such new issuer, or
any other company acquired by the Company in a merger or consolidation, was bound by registration rights that would conflict with the provisions of this Agreement, the Company will use its best efforts to modify any such “inherited”
registration rights so as not to interfere in any material respects with the rights provided under this Agreement, unless otherwise agreed by Holders then holding a majority of Registrable Securities. 

SECTION 2.3 Registration Procedures . If and whenever the Company is required to file a registration statement with respect to, or to
use its reasonable best efforts to effect or cause the registration of, any Registrable Securities under the Securities Act as provided in this Agreement, the Company will as expeditiously as possible: 

  
 -9- 








 (a) promptly prepare and file with the SEC a registration statement on an appropriate form with
respect to such Registrable Securities and use its reasonable best efforts to cause such registration statement to become effective; provided, however, that the Company may discontinue any registration of Securities which it has
initiated for its own account at any time prior to the effective date of the registration statement relating thereto (and, in such event, the Company shall pay the Registration Expenses incurred in connection therewith); and provided,
further, that before filing a registration statement or prospectus, or any amendments or supplements thereto, the Company will (i) furnish to counsel for the sellers of Registrable Securities covered by such registration statement copies
of all documents proposed to be filed, which documents will be subject to the review of such counsel, (ii) fairly consider such reasonable changes in any such documents prior to or after the filing thereof as the counsel to the sellers of
Registrable Securities being sold may request, and (iii) make such of the representatives of the Company as shall be reasonably requested by the sellers of the Registrable Securities being sold available for discussion of such documents; 

(b) prepare and file with the SEC such amendments and supplements to such registration statement and the prospectus used in connection
therewith as may be necessary to keep such registration statement effective for a period not in excess of two (2) years (which period shall not be applicable in the case of a shelf registration effected pursuant to a request under
Section 2.2(b)) and to comply with the provisions of the Securities Act and the Exchange Act with respect to the disposition of all Securities covered by such registration statement during such period in accordance with the intended methods of
disposition by the seller or sellers thereof set forth in such registration statement; provided that before filing a registration statement or prospectus, or any amendments or supplements thereto, the Company will (i) furnish to counsel
for the sellers of Registrable Securities covered by such registration statement copies of all documents proposed to be filed, which documents will be subject to the review of such counsel, (ii) fairly consider such reasonable changes in any
such documents prior to or after the filing thereof as the counsel to the sellers of Registrable Securities being sold may request, and (iii) make such of the representatives of the Company as shall be reasonably requested by the sellers of the

included in such registration statement (including each preliminary prospectus and summary prospectus), in conformity with the requirements of the Securities Act, and such other documents as such seller may reasonably request in order to facilitate
the disposition of the Registrable Securities by such seller; 
 (d) use its reasonable best efforts to register or qualify such Registrable
Securities covered by such registration in such jurisdictions as each seller shall reasonably request, and do any and all other acts and things which may be reasonably necessary or advisable to enable such seller to consummate the disposition in
such jurisdictions of the Registrable Securities owned by such seller; 
 (e) use its reasonable best efforts to cause such Registrable
Securities covered by such registration statement to be registered with or approved by such other governmental agencies or authorities as may be necessary to enable the seller or sellers thereof to consummate the disposition of such Registrable

 (f) notify each seller of any such Registrable Securities covered by such registration statement,
at any time when a prospectus relating thereto is required to be delivered under the Securities Act, of the Company’s becoming aware that the prospectus included in such registration statement, as then in effect, includes an untrue statement of
a material fact or omits to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing, and at the request of any such seller, prepare and furnish to
such seller a reasonable number of copies of an amended or supplemental prospectus as may be necessary so that, as thereafter delivered to the purchasers of such Registrable Securities, such prospectus shall not include an untrue statement of a
material fact or omit to state a material fact required to be stated therein or necessary to make the statements therein not misleading in the light of the circumstances then existing; 

(g) otherwise use its reasonable best efforts to comply with all applicable rules and regulations of the SEC, and make available to its
Security holders, as soon as reasonably practicable (but not more than eighteen (18) months) after the effective date of the registration statement, an earnings statement which shall satisfy the provisions of Section 11(a) of the
Securities Act; 
 (h) (i) use its reasonable best efforts to list such Registrable Securities on any securities exchange on which other
Securities of the Company are then listed if such Registrable Securities are not already so listed and if such listing is then permitted under the rules of such exchange; and (ii) use its reasonable best efforts to provide a transfer agent and
registrar for such Registrable Securities covered by such registration statement not later than the effective date of such registration statement; 

(i) enter into such customary agreements (including an underwriting agreement in customary form), which may include indemnification provisions
in favor of underwriters and other Persons in addition to, or in substitution for the indemnification provisions hereof, and take such other actions as sellers of a majority of such Registrable Securities or the underwriters, if any, reasonably
request in order to expedite or facilitate the disposition of such Registrable Securities; 
 (j) obtain a “cold comfort” letter or
letters from the Company’s independent public accountants in customary form and covering matters of the type customarily covered by “cold comfort” letters as the seller or sellers of a majority of such Registrable Securities shall

to the prospectus or any amendment to any prospectus shall have been filed; (ii) of the receipt of any comments from the SEC; (iii) of any request of the SEC to amend the registration statement or amend or supplement the prospectus or for
additional information; and (iv) of the issuance by the SEC of any stop order suspending the effectiveness of the registration statement or of any order preventing or suspending the use of any preliminary prospectus, or of the suspension of the
qualification of the registration statement for offering or sale in any jurisdiction, or of the institution or threatening of any proceedings for any of such purposes; 

(m) provide each Holder of Registrable Securities included in such registration statement reasonable opportunity to comment on the registration

(n) make every reasonable effort to prevent the issuance of any stop order suspending the effectiveness of the registration statement or of any
order preventing or suspending the use of any preliminary prospectus and, if any such order is issued, to obtain the withdrawal of any such order at the earliest possible moment; 

(o) if requested by the managing underwriter or agent or any Holder of Registrable Securities covered by the registration statement, promptly
incorporate in a prospectus supplement or post-effective amendment such information as the managing underwriter or agent or such Holder reasonably requests to be included therein, including, with respect to
the number of Registrable Securities being sold by such Holder to such underwriter or agent, the purchase price being paid therefor by such underwriter or agent and with respect to any other terms of the underwritten offering of the Registrable
Securities to be sold in such offering; and make all required filings of such prospectus supplement or post-effective amendment as soon as practicable after being notified of the matters incorporated in such
prospectus supplement or post-effective amendment; 
 (p) cooperate with the Holders of Registrable Securities covered by the registration
statement and the managing underwriter or agent, if any, to facilitate the timely preparation and delivery of certificates (not bearing any restrictive legends) representing Securities to be sold under the registration statement, and enable such
Securities to be in such denominations and registered in such names as the managing underwriter or agent, if any, or the Holders may request; 

(q) use its reasonable best efforts to make available the executive officers of the Company to participate with the Holders of Registrable
Securities and any underwriters in any “road shows” that may be reasonably requested by the Holders in connection with distribution of Registrable Securities; 

(r) obtain for delivery to the Holders of Registrable Securities being registered and to the underwriter or agent an opinion or opinions from

 -12- 








 (s) cooperate with each seller of Registrable Securities and each underwriter or agent
participating in the disposition of such Registrable Securities and their respective counsel in connection with any filings required to be made with FINRA. 

SECTION 2.4 Other Registration-Related Matters. 

(a) The Company may require any Person that is Transferring Securities in a Public Offering pursuant to Sections 2.1 or 2.2 to furnish to the
Company in writing such information regarding such Person and pertinent to the disclosure requirements relating to the registration and the distribution of the Registrable Securities which are included in such Public Offering as the Company may from
time to time reasonably request in writing. 
 (b) Each Holder agrees that, upon receipt of any notice from the Company of the happening of
any event of the kind described in Section 2.3(f), it will forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such Registrable Securities until its receipt of the copies of the amended or
supplemented prospectus contemplated by Section 2.3(f) and, if so directed by the Company, each Holder will deliver to the Company or destroy (at the Company’s expense) all copies, other than permanent file copies then in their possession,
of the prospectus covering such Registrable Securities current at the time of receipt of such notice. If the Company gives any such notice, the period for which the Company will be required to keep the registration statement effective will be
extended by the number of days during the period from and including the date of the giving of such notice pursuant to Section 2.3(f) to and including the date when each seller of Registrable Securities covered by such registration statement has
received the copies of the supplemented or amended prospectus contemplated by Section 2.3(f). 
 (c) Each Holder agrees that, upon
receipt of any notice from the Company of the happening of any event of the kind described in Section 2.3(l)(iv), it will forthwith discontinue disposition of Registrable Securities pursuant to the registration statement covering such
Registrable Securities until the lifting of such stop order, other order or suspension or the termination of such proceedings and, if so directed by the Company, each Holder will deliver to the Company or destroy (at the Company’s expense) all
copies, other than permanent file copies then in its possession, of the prospectus covering such Registrable Securities current at the time of receipt of such notice. If the Company gives any such notice, the period for which the Company will be
required to keep the registration statement effective will be extended by the number of days during the period from and including the date of the giving of such notice pursuant to Section 2.3(l)(iv) to and including the date when such stop
order, other order or suspension is lifted or such proceedings are terminated. 
 (d) (i) Each Holder (x) hereby agrees, with respect to
the Registrable Securities owned by such Holder, to be bound by any and all restrictions on the sale, disposition, distribution, hedging or other Transfer of any interest in Registrable Securities imposed on


  
 -13- 








 
Blackstone[, Summit, Black Horse or the Director Stockholders]3 and/or [its] [their respective] Affiliates in connection with the IPO by the
underwriters managing such offering for the duration of the term of such restriction (the period in which such sale, disposition, distribution, hedging or other Transfer of any interest is restricted, the “Lockup Period”) and
(y) will, in connection with a Public Offering of the Company’s equity Securities (whether for the Company’s account or for the account of any Holder or Holders, or both), upon the request of the Company or of the underwriters
managing any underwritten offering of the Company’s Securities, agree in writing not to effect any sale, disposition or distribution of Registrable Securities (other than those included in the Public Offering) without the prior written consent
of the managing underwriter for such period of time commencing seven (7) days before and ending one hundred eighty (180) days (or such earlier date as the managing underwriter shall agree) after the effective date of such registration;
provided that the Company shall cause all directors and officers of the Company, Holders of more than 5% of the Registrable Securities and all other Persons with registration rights with respect to the Company’s Securities (whether or
not pursuant to this Agreement) to enter into agreements similar to those contained in this Section 2.4(d)(i) (without regard to this proviso); and (ii) the Company and its Subsidiaries will, in connection with an underwritten Public
Offering of the Company’s Securities in respect of which Registrable Securities are included, upon the request of the underwriters managing such offering, agree in writing not to effect any sale, disposition or distribution of equity Securities
of the Company (other than those included in such Public Offering, offered pursuant to Section 2.2(f), offered on Form S-8, issuable upon conversion of Securities or upon the exercise of options, or the grant of options in the ordinary course
of business pursuant to then-existing management equity plans or equity-based employee benefit plans or as otherwise permitted by Section 6(e)(i) of the Underwriting Agreement dated [•], 2014 by and among the Company, Goldman,
Sachs & Co., Merrill Lynch, Pierce, Fenner & Smith Incorporated and Credit Suisse Securities (USA) LLC as representatives of the several underwriters named in Schedule I thereto, in each case outstanding on the date a notice is
given by the Company pursuant to Section 2.1(a) or a request is made pursuant to Section 2.2(a), as the case may be), without the prior written consent of the managing underwriter, for such period of time commencing seven (7) days
before and ending one hundred eighty (180) days (or such earlier date as the managing underwriter shall agree) after the effective date of such registration. 

(e) With a view to making available the benefits of certain rules and regulations of the SEC which may at any time permit the sale of
Securities of the Company to the public without registration after such time as a public market exists for Registrable Securities, the Company agrees: 

(i) to make and keep public information available, as those terms are understood and defined in Rule 144 under the Securities
Act, at all times after the effective date of the first registration under the Securities Act filed by the Company for an offering of its Securities to the public; 

(ii) to use its commercially reasonable efforts to then file with the SEC in a timely manner all reports and other documents
required of the Company under the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); and 
  

 

	3 	To be confirmed. 


  
 -14- 








 (iii) so long as a Holder owns any Registrable Securities, to furnish to such
Holder promptly upon request: (A) a written statement by the Company as to its compliance with the reporting requirements of Rule 144 (at any time after ninety (90) days after the effective date of the first registration statement filed by
the Company for an offering of its Securities to the public), and of the Securities Act and the Exchange Act (at any time after it has become subject to such reporting requirements); (B) a copy of the most recent annual or quarterly report of
the Company; and (C) such other reports and documents of the Company as such Holder may reasonably request in availing itself or himself of any rule or regulation of the SEC allowing such Holder to sell any such Securities without registration.

 (f) Counsel to represent Holders of Registrable Securities shall be selected by the Holders of at least a majority of the Registrable
Securities included in the relevant registration. 
 (g) Each of the parties hereto agrees that the registration rights provided to the
Holders herein are not intended to, and shall not be deemed to, override or limit any other restrictions on Transfer to which any such Holder may otherwise be subject. 

ARTICLE III 

INDEMNIFICATION 
 SECTION
3.1 Indemnification by the Company. If any registration of any Securities of the Company under the Securities Act pursuant to Section 2.1 or 2.2, the Company hereby indemnifies and agrees to hold harmless, to the fullest extent permitted
by Law, each Holder who sells Registrable Securities covered by such registration statement, each Affiliate of such Holder and their respective directors and officers or general and limited partners (and the directors, officers, employees,
Affiliates and controlling Persons of any of the foregoing), each other Person who participates as an underwriter in the offering or sale of such Securities and each other Person, if any, who controls such Holder or any such underwriter within the
meaning of the Securities Act (each, and “Indemnified Party” and collectively, the “Indemnified Parties”), against any and all losses, claims, damages or liabilities, joint or several, and reasonable and documented
expenses to which such Indemnified Party may become subject under the Securities Act, common law or otherwise, insofar as such losses, claims, damages or liabilities (or actions or proceedings in respect thereof, whether or not such Indemnified
Party is a party thereto) arise out of or are based upon: (a) any untrue statement or alleged untrue statement of any material fact contained in any registration statement under which such Securities were registered under the Securities Act,
any preliminary, final or summary prospectus contained therein, or any amendment or supplement thereto, or any document incorporated by reference therein, or any other such disclosure document (including reports and other documents filed under the
Exchange Act and any document incorporated by reference therein) or related document or report; (b) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not
misleading, in the case of a prospectus, in the light of the circumstances when they were made; or (c) any violation or alleged violation by the 

  
 -15- 








 
Company or any of its Subsidiaries of any federal, state, foreign or common law rule or regulation applicable to the Company or any of its Subsidiaries and relating to action or inaction in
connection with any such registration, disclosure document or related document or report, and the Company will reimburse such Indemnified Party for any legal or other expenses reasonably incurred by it in connection with investigating or defending
any such loss, claim, liability, action or proceeding; provided that the Company will not be liable to any Indemnified Party in any such case to the extent that any such loss, claim, damage, liability (or action or proceeding in respect
thereof) or expense arises out of or is based upon any untrue statement or alleged untrue statement or omission or alleged omission made in such registration statement, in any such preliminary, final or summary prospectus, or any amendment or
supplement thereto in reliance upon and in conformity with written information with respect to such Indemnified Party furnished to the Company by such Indemnified Party expressly for use in the preparation thereof. Such indemnity will remain in full
force and effect regardless of any investigation made by or on behalf of such Holder or any Indemnified Party and will survive the Transfer of such Securities by such Holder or any termination of this Agreement. 

SECTION 3.2 Indemnification by the Holders and Underwriters. The Company may require, as a condition to including any Registrable
Securities in any registration statement filed in accordance with Section 2.1 or 2.2, that the Company shall have received an undertaking reasonably satisfactory to it from the Holder of such Registrable Securities or any prospective
underwriter to indemnify and hold harmless (in the same manner and to the same extent as set forth in Section 3.1) the Company, all other Holders or any prospective underwriter, as the case may be, and any of their respective Affiliates,
directors, officers and controlling Persons, with respect to any untrue statement in or omission from such registration statement, any preliminary, final or summary prospectus contained therein, or any amendment or supplement, if such untrue
statement or omission was made in reliance upon and in conformity with written information with respect to such Holder or underwriter furnished to the Company by such Holder or underwriter expressly for use in the preparation of such registration
statement, preliminary, final or summary prospectus or amendment or supplement, or a document incorporated by reference into any of the foregoing. Such indemnity will remain in full force and effect regardless of any investigation made by or on
behalf of the Company or any of the Holders, or any of their respective Affiliates, directors, officers or controlling Persons and will survive the Transfer of such Securities by such Holder. In no event shall the liability of any selling Holder of
Registrable Securities hereunder be greater in amount than the dollar amount of the proceeds actually received by such Holder upon the sale of the Registrable Securities giving rise to such indemnification obligation. 

SECTION 3.3 Notices of Claims, Etc. Promptly after receipt by an Indemnified Party hereunder of written notice of the commencement of
any action or proceeding with respect to which a claim for indemnification may be made pursuant to this Article III, such Indemnified Party will, if a claim in respect thereof is to be made against an indemnifying party, give written notice to the
latter of the commencement of such action; provided that the failure of the Indemnified Party to give notice as provided herein will not relieve the indemnifying party of its obligations under Section 3.1 or 3.2, except to the extent
that the indemnifying party is actually prejudiced by such failure to give notice. In case any such action is brought against an Indemnified Party, unless in such Indemnified Party’s reasonable judgment a conflict of interest between such
indemnified and indemnifying parties may exist in respect of such claim, the 

  
 -16- 








 
indemnifying party will be entitled to participate in and to assume the defense thereof, jointly with any other indemnifying party similarly notified to the extent that it may wish, with counsel
selected by the Holders of at least a majority of the Registrable Securities included in the relevant registration, and after notice from the indemnifying party to such Indemnified Party of its election so to assume the defense thereof, the
indemnifying party will not be liable to such Indemnified Party for any legal or other expenses subsequently incurred by the latter in connection with the defense thereof other than reasonable costs of investigation. If, in such Indemnified
Party’s reasonable judgment, having common counsel would result in a conflict of interest between the interests of such indemnified and indemnifying parties, then such Indemnified Party may employ separate counsel reasonably acceptable to the
indemnifying party to represent or defend such Indemnified Party in such action, it being understood, however, that the indemnifying party will not be liable for the reasonable fees and expenses of more than one separate firm of attorneys at any
time for all such Indemnified Parties (and not more than one separate firm of local counsel at any time for all such Indemnified Parties) in such action. No indemnifying party will consent to entry of any judgment or enter into any settlement which
does not include as an unconditional term thereof the giving by the claimant or plaintiff to such Indemnified Party of a release from all liability in respect of such claim or litigation. 

SECTION 3.4 Contribution. If the indemnification provided for hereunder from the indemnifying party is unavailable to an Indemnified
Party hereunder in respect of any losses, claims, damages, liabilities or expenses referred to herein for reasons other than those described in the proviso in the first sentence of Section 3.1, then the indemnifying party, in lieu of
indemnifying such Indemnified Party, shall contribute to the amount paid or payable by such Indemnified Party as a result of such losses, claims, damages, liabilities or expenses in such proportion as is appropriate to reflect the relative fault of
the indemnifying party and Indemnified Parties in connection with the actions which resulted in such losses, claims, damages, liabilities or expenses, as well as any other relevant equitable considerations. The relative fault of such indemnifying
party and Indemnified Parties shall be determined by reference to, among other things, whether any action in question, including any untrue or alleged untrue statement of a material fact or omission or alleged omission to state a material fact, has
been made by, or relates to information supplied by, such indemnifying party or Indemnified Parties, and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such action. The amount paid or
payable by a party under this Section 3.4 as a result of the losses, claims, damages, liabilities and expenses referred to above shall be deemed to include any legal or other fees or expenses reasonably incurred by such party in connection with
any investigation or proceeding. In no event shall the liability of any selling Holder of Registrable Securities hereunder be greater in amount than the dollar amount of the proceeds actually received by such Holder upon the sale of the Registrable
Securities giving rise to such contribution obligation. 
 The parties hereto agree that it would not be just and equitable if contribution
pursuant to this Section 3.4 were determined by pro rata allocation or by any other method of allocation which does not take account of the equitable considerations referred to in the immediately preceding paragraph. No Person guilty of
fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any Person who was not guilty of such fraudulent misrepresentation. 

  
 -17- 








 SECTION 3.5 Other Indemnification. Indemnification similar to that specified in this
Article III (with appropriate modifications) shall be given by the Company and each seller of Registrable Securities with respect to any required registration or other qualification of Securities under any Law or with any Governmental Authority
other than as required by the Securities Act. 
 SECTION 3.6 Non-Exclusivity. The obligations of the parties under this Article III
will be in addition to any liability which any party may otherwise have to any other party. 
 ARTICLE IV 

OTHER 
 SECTION 4.1
Notices. Any notice, request, instruction or other document to be given hereunder by any party hereto to another party hereto shall be in writing and shall be deemed given (a) when delivered personally, (b) five (5) Business

SECTION 4.2 Assignment. Neither the Company nor any Holder shall assign all or any part of this Agreement without the prior written
consent of the Company and Blackstone; provided, however, that, without the prior written consent of the Company, any Blackstone Entity may assign its rights and obligations under this Agreement in whole or in part to (x) any of
its Affiliates and (y) any Person who becomes a holder of Registrable Securities upon a distribution by such Blackstone Entity of shares of Common Stock to its members, limited partners or stockholders that becomes a party hereto by executing
and delivering an assignment and joinder agreement to the Company, substantially in the form of Exhibit A to this Agreement. Except as otherwise provided herein, this Agreement will inure to the benefit of and be binding on the parties hereto
and their respective successors and permitted assigns. 
 SECTION 4.3 Amendments; Waiver. This Agreement may be amended, supplemented
or otherwise modified only by a written instrument executed by the Company and the Holders holding a majority of the Registrable Securities subject to this Agreement; provided that no such amendment, supplement or other modification shall
adversely affect the economic interests of any Holder hereunder disproportionately to other Holders without the written consent of such Holder. For the avoidance of doubt, no consent pursuant to this Section 4.3 shall be 

  
 -19- 








 
required in connection with any amendment or revision to Schedule A unless such amendment or revision is to remove a Holder from such schedule at a time when such Holder would otherwise be
entitled to registration rights herein. No waiver by any party of any of the provisions hereof will be effective unless explicitly set forth in writing and executed by the party so waiving. Except as provided in the preceding sentence, no action
taken pursuant to this Agreement, including without limitation, any investigation by or on behalf of any party, will be deemed to constitute a waiver by the party taking such action of compliance with any covenants or agreements contained herein.
The waiver by any party hereto of a breach of any provision of this Agreement will not operate or be construed as a waiver of any subsequent breach. 

SECTION 4.4 Third Parties. This Agreement does not create any rights, claims or benefits inuring to any person that is not a party
hereto nor create or establish any third party beneficiary hereto. 
 SECTION 4.5 Governing Law. This Agreement shall be governed by,
and construed and enforced in accordance with, the laws of the State of Delaware. 
 SECTION 4.6 Jurisdiction. The Delaware Court of
Chancery and any state appellate court therefrom within the State of Delaware (or, if the Delaware Court of Chancery declines to accept jurisdiction over a particular matter, any state or federal court within the State of Delaware) shall have
exclusive jurisdiction over the parties with respect to any dispute or controversy between them arising under or in connection with this agreement and, by execution and delivery of this agreement, each of the parties to this Agreement submits to the
exclusive jurisdiction of those courts, including but not limited to the in personam and subject matter jurisdiction of those courts, waives any objections to such jurisdiction on the grounds of venue or forum non conveniens, the absence of in
personam or subject matter jurisdiction and any similar grounds, consents to service of process by mail (in accordance with the notice provisions of this Agreement) or any other manner permitted by Law, and irrevocably agrees to be bound by any
judgment rendered thereby in connection with this Agreement. 
 SECTION 4.7 MUTUAL WAIVER OF JURY TRIAL. THE PARTIES HERETO WAIVE ALL
RIGHT TO TRIAL BY JURY IN ANY ACTION, SUIT OR PROCEEDING BROUGHT TO ENFORCE OR DEFEND ANY RIGHTS OR REMEDIES UNDER THIS AGREEMENT. 

SECTION 4.8 Specific Performance. Each of the parties hereto acknowledges and agrees that if there is any breach of this Agreement by
any of them, the non-breaching party would be irreparably harmed and could not be made whole by monetary damages. Each party accordingly agrees to waive the defense in any action for specific performance that a remedy at law would be adequate and
that the parties, in addition to any other remedy to which they may be entitled at law or in equity, shall be entitled to compel specific performance of this Agreement. 

SECTION 4.9 Entire Agreement. This Agreement sets forth the entire understanding of the parties hereto with respect to the subject
matter hereof. There are no agreements, representations, warranties, covenants or undertakings with respect to the subject matter hereof other than those expressly set forth herein. This Agreement supersedes all other 

  
 -20- 








 
prior agreements and understandings between the parties with respect to such subject matter. For the avoidance of doubt, this Agreement supersedes all other registration rights with respect to
the Company’s Common Stock that are forth in the Securityholders Agreement dated as of November 16, 2012 among 313 Acquisition LLC and the other parties thereto. 

SECTION 4.10 Severability. If one or more of the provisions, paragraphs, words, clauses, phrases or sentences contained herein, or the
application thereof in any circumstances, is held invalid, illegal or unenforceable in any respect for any reason, the validity, legality and enforceability of any such provision, paragraph, word, clause, phrase or sentence in every other respect
and of the remaining provisions, paragraphs, words, clauses, phrases or sentences hereof shall not be in any way impaired, it being intended that all rights, powers and privileges of the parties hereto shall be enforceable to the fullest extent
permitted by Law. 
 SECTION 4.11 Counterparts. This Agreement may be executed in any number of counterparts, each of which will be
deemed to be an original and all of which together will be deemed to be one and the same instrument. 
 SECTION 4.12 Effectiveness.

 This Agreement shall become effective, as to any Holder, as of the date signed by the Company and countersigned by such Holder. 

SECTION 4.13 Confidentiality. 

Blackstone, Summit, Black Horse and each Director Stockholder agrees that all material non-public information provided pursuant to or in
accordance with the terms of this Agreement shall be kept confidential by the person to whom such information is provided, until such time as such information becomes public other than through violation of this provision. Notwithstanding the
foregoing, any party may disclose the information (1) if required to do so by any law, rule, regulation, order, decree or subpoena of any governmental agency or authority or court or (2) such information becomes generally available to the public
other than as a result of a disclosure or failure to safeguard such information by such Person.
