LIABLE TO THE OTHER PARTY FOR ANY INDIRECT, SPECIAL, INCIDENTAL, CONSEQUENTIAL OR EXEMPLARY DAMAGES, INCLUDING, WITHOUT LIMITATION, DAMAGES FOR LOSS OF REVENUE, LOSS OF PROFITS, OR LOSS OF CUSTOMER’S CLIENTS OR GOODWILL, ARISING IN ANY MANNER
FROM THIS AGREEMENT AND/OR THE PERFORMANCE OR NONPERFORMANCE HEREUNDER. WIN SHALL HAVE NO LIABILITY OR RESPONSIBILITY FOR THE CONTENT OF ANY COMMUNICATIONS TRANSMITTED VIA THE SERVICE BY CUSTOMER OR ANY OTHER PARTY. 

12.2 THE LIABILITY OF WIN WITH RESPECT TO THE SERVICES PROVIDED UNDER THIS AGREEMENT SHALL BE LIMITED TO CIRCUMSTANCES IN WHICH THERE HAS BEEN A SERVICE

 ARTICLE XIII 

COMPLIANCE WITH LAWS 
 13.1 Each Party
shall comply with all applicable laws, regulations, court decisions or administrative rulings regarding the provision or use of the Services. Failure to do so shall constitute a material breach of the Agreement. 

13.2 Certifications. Each party has obtained all certifications necessary to provide its services to End Users and shall maintain all such
certifications for the duration of this Agreement. Upon WIN’s request, Customer shall provide WIN with Customer’s certifications. Customer shall indemnify, defend and hold harmless WIN against all claims or liability due to or arising out
of failure of Customer to obtain any permit or other consent as may be required from any local government or other regulatory body for use of the Services. In the event it is found that a Party does not have any necessary certificates,
authorizations, or permits, such Party will promptly seek to obtain same. Failure to have any such certification, authorization, or permit will not be deemed a material breach unless it causes material adverse consequences to the other Party
under this Agreement. 
 13.3 Duty to Confirm Registration of Customer. Before Services can be provided, and if applicable under the circumstances,
Customer may be required to provide evidence of its filing of FCC Form 499-A as required by 47 CFR 64.1195(h). Regardless of any affirmative duty of WIN under the FCC rule, Customer’s failure to file FCC Form 499-A, if required, constitutes
willful misconduct and Customer agrees to indemnify and hold WIN harmless due to such failure. 
 13.4 Requests for End User or Customer Information and
Communications Assistance Law Enforcement Act (CALEA) Of 1994. In the event WIN is in receipt of a request for information regarding Customer or its End User(s) or a CALEA request, from law enforcement, a governmental entity or other
entity or person (“Requesting Entity”), WIN will inform Customer of such request (if not prohibited from doing so). WIN will also gather the information or facilitate the request if the ability to do so is uniquely within WIN’s power
(i.e., Customer obtains a switch-based Service and law enforcement submits a CALEA request). WIN will then either respond to the Requesting Entity or provide the information to Customer to submit to the Requesting Entity, at WIN’s option. Each
Party shall indemnify and hold the other Party harmless from any and all penalties imposed upon the other Party by a third party for noncompliance with CALEA and shall, at the noncompliant Party’s sole cost and expense, modify or replace any
equipment, facilities, or services provided to the other Party under this Agreement to ensure that such equipment, facilities, and services fully comply with CALEA. 

ARTICLE XIV 

UNAUTHORIZED USE AND NETWORK/ 

EQUIPMENT SECURITY 
 14.1
Unauthorized/Fraudulent Use. 
 14.1.1 WIN in its normal course of business will use reasonable efforts during business hours to notify
Customer of any fraud detected during their normal usage review for fraud; however, Customer, and not WIN, shall bear the risk of loss arising from any unauthorized or fraudulent usage of Services provided under this Agreement to Customer, unless
affirmatively caused by WIN (and not due to any failure to detect or notify Customer of fraud). WIN may take any and all action it deems appropriate (including blocking access to particular calling numbers or geographic areas) to prevent or
terminate any fraud or abuse in connection with the Services. 
 14.1.2 The Parties agree to cooperate with one another to investigate,
minimize, and take corrective action in cases of fraud. The Parties’ fraud minimization procedures are to be cost-effective and implemented so as not to unduly burden or harm one Party as compared to the other. 

14.2 Network Security. Customer and its customers and End Users are responsible for the security of their own networks and equipment. Neither Party
assumes responsibility or liability for failures or breach of protective measures on the other Party’s network, whether implied or actual, even in the event that the security measures have been installed or configured by the Party whose network
fails or is breached. The Parties shall be solely responsible for addressing problems on their respective networks and escalating problems to the other Party for resolution when such problem involves compromise of the other Party’s security.

adherence to the WIN Acceptable Use Policy, attached hereto as Schedule 2. In the event that Customer (or Customer’s End Users) utilizes the Services provided hereunder in a manner which generates a complaint to WIN, WIN may provide
Customer’s name and contact information to the complaining party. In the event WIN receives repeated complaints regarding Customer’s (or Customer’s End Users’) use of the Services, WIN may in its reasonable discretion
deem this to be a material breach of this Agreement.
 ARTICLE XV

15.1 Confidentiality. During the term of this Agreement and for a period of one (1) year thereafter, neither Party shall disclose any terms of
this Agreement, including pricing or any other confidential information of the other Party. For purposes of this Agreement, the term “confidential information” shall mean information in written or other tangible form that a party should
reasonably understand is confidential. Any confidential information transmitted orally shall be identified as such at the time of its disclosure. All confidential information shall remain the property of the disclosing Party. A Party receiving
confidential information shall: (i) use or reproduce such information only when necessary to perform this Agreement; (ii) provide at least the same care to avoid disclosure or unauthorized use of such information as it provides to protect
its own confidential information; (iii) limit access to such information to its employees or agents who need such information to perform this Agreement; and (iv) return or destroy all such information, including copies, after the need for
it has expired, upon request of the disclosing Party, or upon termination of this Agreement. 
 The Party to whom confidential information is disclosed
shall have none of the obligation above for confidential information which: (i) was previously known to such Party free of any obligation to keep it confidential; (ii) is or becomes publicly available by other than unauthorized disclosure;
(iii) is developed by or on behalf of such Party independent of any confidential information furnished under this agreement; (iv) is received from a third party whose disclosure does not violate any confidentiality obligation; or
(v) is disclosed pursuant to the requirement or request of a governmental agency or court of competent jurisdiction to the extent such disclosure is required by a valid law, regulation or court order. 

15.2 Intellectual Property and Digital Millennium Copyright Act (“DMCA”). This Agreement confers no right to use the name, service marks,
trademarks, copyrights, or patents of either Party except as expressly provided herein or in the Parties’ IP Matters Agreement, which is incorporated herein by reference. Neither Party shall take any action, which would compromise the
registered copyrights or service marks of the other. In the event WIN creates any custom software enhancements in providing Services to Customer under this Agreement, such software enhancements shall be deemed solely the intellectual property of WIN
unless otherwise provided in a SOW. Customer hereby disclaims all right, title, and interest in such custom software enhancements, including United States and foreign patent, copyright, and other intellectual property rights. Customer shall
indemnify WIN if its domain name or combination of the Services provided by WIN with services or equipment not provided by WIN infringes or is alleged to infringe on any third party’s intellectual property rights. Customer shall comply with all
provisions of the DMCA Title II with respect to limiting liability for copyright infringement. Customer shall: (a) adopt and implement a policy of terminating accounts or subscriptions of repeat infringers; (b) inform subscribers and/or
account holders of such policy; (c) accommodate and not interfere with standard technical measures as defined by the DMCA; (d) designate an agent to receive notification of alleged acts of infringement, file information related to such
designated agent with the Copyright Office, and notify subscribers or account holders of the designated agent and such designated agent’s contact information; and (e) comply with the DMCA’s rules governing notification and
counter-notification and procedures for removing or blocking access to (or restoring access to) content alleged to be infringing.

demands, suits, liabilities, fines, penalties and expenses (including reasonable attorneys’ fees) that arise out of or result from: (i) any environmental hazard that the indemnifying Party, its contractors or agents introduce to the work
locations, or (ii) the presence or release of any environmental hazard for which the indemnifying Party is responsible under Applicable Law. 

ARTICLE XVII 
 NETWORK
SECURITY 
 17.1 Protection of Service and Property. Subject to Sec. 10.4 and 12 herein, each Party shall exercise the same degree of care
to prevent harm or damage to the other Party and any third parties, its employees, agents or End Users, or their property as it employs to protect its own personnel, Subscribers, and property, etc., but in no case less than a commercially reasonable
degree of care. 
 ARTICLE XVIII 

MISCELLANEOUS 
 18.1 Entire
Agreement/Modifications/Waivers. This Agreement represents the entire agreement of the Parties with respect to the subject matter hereof and supersedes all other agreements, written or oral, between the Parties relating to the Services. As of
the Effective Date hereof, any and all Service provided pursuant to any prior agreements shall be provided pursuant to the terms of this Agreement. This Agreement may only be modified by written agreement of both parties. No term herein shall be
deemed waived or breach or default excused unless in writing and signed by the party against which it is to be enforced. Additionally, no consent by a Party to, or waiver of, a breach or default by the other, whether express or implied, shall
constitute a consent to or waiver of, any subsequent breach or default. 
 18.2 Contractual Relationships with Third Parties. Services provided by
WIN through Third Parties such as Incumbents and underlying per minute long distance providers of WIN shall be subject to, and governed by, the terms and conditions of WIN’s agreements with those third parties. WIN shall not be liable for any
failure to perform to the extent such failure is due to an act or omission of an Incumbent. 
 18.3 Assignment. Neither this Agreement, nor any
rights or obligations under it may be assigned by Customer without the prior written consent of WIN, which consent shall not be unreasonably withheld. 

18.4 Partial Invalidity. If any provision of this Agreement shall be held to be invalid or unenforceable (either under current law or in the future),
such invalidity or unenforceability shall not invalidate or render this Agreement unenforceable, but rather this Agreement shall be construed as if not containing the invalid or unenforceable provision. However, if such provision is an essential
element of this Agreement, the Parties shall promptly attempt to negotiate a substitute therefore. 
 18.5 Regulatory Requirements. If any
Regulatory Requirement has the effect of canceling, changing or superseding any material term or provision of this Agreement, results in cost increases to WIN to provide such Services, and/or results in WIN being unable to obtain the technology used
to provide the Services that was available as of the date of this Agreement, the Parties will negotiate new terms, conditions and pricing that are consistent with the form, intent and purpose of this Agreement and are necessary to comply with or
accommodate the Regulatory Requirement. If the Parties cannot agree to such modifications within thirty (30) days after the Regulatory Requirement is effective, or such other period as mutually agreed by the Parties, then either Party may
terminate this Agreement and/or Attachment impacted by the Regulatory Requirement by providing sixty (60) days written notice to the other Party. WIN agrees that if any ILEC proposes an ICA Change that affects the services provided by WIN to
Customer, WIN will: (i) provide notice to Customer within 15 days of notification by the ILEC; and (ii) use its best efforts to negotiate rates, terms and conditions that minimize the impact on the costs and services Customer purchases
under this agreement.

deemed to create any joint venture, partnership or agency between WIN and Customer. The Parties are independent contractors and shall not be deemed to have any other relationship. Neither Party shall have, or hold itself out as having, the power or
authority to bind or create liability for the other by its intentional or negligent act. 
 18.7 Governing Law. This Agreement shall be interpreted,
construed and enforced in accordance with the laws of the State of Arkansas, without regard to choice of law provisions.

REGISTRATION RIGHTS 

Section 2.01 Registration. 

(a) Prior to the fifth anniversary of the Distribution Date, the WHI Group or, following the Sale or Transfer by the WHI Group of at least 90%
of the Registrable Securities owned by it on the date of this Agreement, any Holders acting together which collectively hold 10% or more of the then outstanding Registrable Securities (collectively, the “Initiating Holder”) shall
have the right to request that CS&L file a Registration Statement, on behalf of itself or, in the case of the WHI Group, on behalf of the Participating Banks, with the SEC on the appropriate registration form for all or part of the Registrable
Securities held by such Initiating Holder, by delivering a written request thereof to CS&L specifying the number of Registrable Securities such Initiating Holder wishes to register (a “Demand Registration”); provided,
that Holders may not make more than one Demand Registration during any 90-day period prior to the first anniversary of the Distribution Date and not more than two Demand Registrations during any subsequent 365-day period (unless, with respect to any
such Demand Registration, such Demand Registration is withdrawn prior to the filing of a Registration Statement or the Registration effected pursuant thereto becomes subject to a Blackout Period, in each case pursuant to
Section 2.01(d)). CS&L shall (i) within five days of the receipt of a Demand Registration, give written notice of such Demand Registration to all Holders of Registrable Securities (other than the Initiating Holder),
(ii) use its reasonable best efforts to prepare and file the Registration Statement as expeditiously as possible but in any event within 30 days of such request, and (iii) use its reasonable best efforts to cause the Registration Statement
to become effective in respect of such Demand Registration in accordance with the intended method of distribution set forth in the written request delivered by the Initiating Holder. CS&L shall include in such Registration all Registrable
Securities with respect to which CS&L receives, within the 10 days immediately following the receipt by the Holder(s) of such notice from CS&L, a request for inclusion in the Registration from the Holder(s) thereof. Each such request from a
Holder of Registrable Securities for inclusion in the Registration shall also specify the aggregate amount of Registrable Securities proposed to be Registered. The Initiating Holder may request that the Registration Statement be on any appropriate
form, including Form S-11 in the case of secondary equity offerings, Form S-4 in the case of an Exchange Offer or a Shelf Registration Statement, and CS&L shall effect the Registration on the form so requested. 

(b) The Holders may collectively make a total of two Demand Registration requests pursuant to Section 2.01(a) (including any
exercise of rights to Demand Registration transferred pursuant to Section 4.06 and including any exercise of rights to Demand Registration made pursuant to any registration rights agreement entered into pursuant to
Section 2.05). 

  
 8 

 (c) CS&L shall be deemed to have effected a Registration for purposes of this
Section 2.01 if the Registration Statement is declared effective by the SEC or becomes effective upon filing with the SEC and remains effective until the earlier of (i) the date when all Registrable Securities thereunder have been
Sold and (ii) 60 days from the effective date of the Registration Statement (or from the date the applicable Prospectus is filed with the SEC if CS&L is satisfying a request for a Demand Registration by filing a Prospectus under an
effective Shelf Registration Statement) (the “Registration Period”). No Registration shall be deemed to have been effective if the conditions to closing specified in the underwriting agreement or dealer manager agreement, if any,
entered into in connection with such Registration are not satisfied by reason of a wrongful act, misrepresentation or breach of such applicable underwriting agreement or dealer manager agreement by any member of the CS&L Group. If during the
Registration Period, such Registration is interfered with by any stop order, injunction or other order or requirement of the SEC or other Governmental Authority or the need to update or supplement the Registration Statement, the Registration Period
shall be extended on a day-for-day basis for any period in which the Holder(s) is unable to complete an offering as a result of such stop order, injunction or other order or requirement of the SEC or other Governmental Authority. 

(d) With respect to any Registration Statement, whether filed or to be filed pursuant to this Agreement, if CS&L shall reasonably
determine, upon the good faith advice of legal counsel, that maintaining the effectiveness of such Registration Statement or filing an amendment or supplement thereto (or, if no Registration Statement has yet been filed, filing such a Registration
Statement) would require the public disclosure of material nonpublic information concerning any transaction or negotiations involving CS&L or any of its consolidated Subsidiaries that would require the public disclosure of material non-public
information concerning any transaction or negotiations involving CS&L or any of its consolidated subsidiaries that would materially interfere with such transaction or negotiations (a “Disadvantageous Condition”), CS&L may,
for the shortest period reasonably practicable, and in any event for not more than 30 consecutive calendar days (a “Blackout Period”), notify the Holders whose offers and Sales of Registrable Securities are covered (or to be
covered) by such Registration Statement (a “Blackout Notice”) that such Registration Statement is unavailable for use (or will not be filed as requested). Upon the receipt of any such Blackout Notice, the Holders shall forthwith
discontinue use of the Prospectus contained in any effective Registration Statement; provided, that, if at the time of receipt of such Blackout Notice any Holder shall have Sold its Registrable Securities (or have signed a firm commitment
underwriting agreement with respect to the purchase of such shares) and the Disadvantageous Condition is not of a nature that would require a post-effective amendment to the Registration Statement, then CS&L shall use its reasonable best efforts
to take such action as to eliminate any restriction imposed by federal securities laws on the timely delivery of such Registrable Securities to the extent permitted under such applicable laws prior to disclosure of material information relating to
such Disadvantageous Condition. When any Disadvantageous Condition as to which a Blackout Notice has been previously delivered shall cease to exist, CS&L shall as promptly as reasonably practicable notify the Holders and take such actions in
respect of such Registration Statement as are otherwise required by this Agreement. The effectiveness period for any Demand Registration for which CS&L has given notice of a Blackout Period shall be increased by the length of time of such
Blackout Period. CS&L shall not impose, in any 365-day period, more than two Blackout Periods; such Blackout Periods shall not be permitted to run consecutively; and such Blackout Periods may not be prompted by the same Disadvantageous
Condition. If CS&L declares a 

  
 9 

 
Blackout Period with respect to a Demand Registration for a Registration Statement that has not yet been declared effective, (i) the Holders may by notice to CS&L withdraw the related
Demand Registration request without such Demand Registration request counting against the number of Demand Registration requests permitted to be made under Section 2.01(b) and (ii) the Holders shall not be responsible for any of
CS&L’s related Registration Expenses. 
 (e) If the Initiating Holder so indicates at the time of its request pursuant to
Section 2.01(a), such offering of Registrable Securities shall be in the form of an Underwritten Offering or an Exchange Offer, and CS&L shall include such information in the written notice to the Holders required under
Section 2.01(a). In the event that the Initiating Holder intends to Sell the Registrable Securities by means of an Underwritten Offering or Exchange Offer, the right of any Holder to include Registrable Securities in such registration
shall be conditioned upon such Holder’s participation in such Underwritten Offering or Exchange Offer and the inclusion of such Holder’s Registrable Securities in the Underwritten Offering or the Exchange Offer to the extent provided
herein. The Holders of a majority of the outstanding Registrable Securities being included in any Underwritten Offering or Exchange Offer shall select the underwriter(s) in the case of an Underwritten Offering or the dealer manager(s) in the case of
an Exchange Offer, provided that such underwriter(s) or dealer manager(s) are reasonably acceptable to CS&L. 
 (f) If the managing
underwriter or underwriters of a proposed Underwritten Offering of Registrable Securities included in a Registration pursuant to this Section 2.01 inform(s) in writing the Holders participating in such Registration that, in its or their
opinion, the number of securities requested to be included in such Registration exceeds the number that can be Sold in such offering without being reasonably likely to have a significant adverse effect on the price, timing or distribution of the
securities offered or the market for the securities offered, the number of Registrable Securities to be included in such Registration shall be (i) reduced to the maximum number recommended by the managing underwriter or underwriters and
(ii) allocated first to any members of the WHI Group participating in the Registration, and then pro rata among the other Holders, including the Initiating Holder (other than any member of the WHI Group), in proportion to the number of
Registrable Securities each Holder has requested to be included in such Registration; provided, that the Initiating Holder may notify CS&L in writing that the Registration Statement shall be abandoned or withdrawn, in which event CS&L
shall abandon or withdraw such Registration Statement. In the event the Initiating Holder notifies CS&L that such Registration Statement shall be abandoned or withdrawn prior to the filing of the Registration Statement, such Holder shall not be
deemed to have requested a Demand Registration pursuant to Section 2.01(a), and CS&L shall not be deemed to have effected a Demand Registration pursuant to Section 2.01(c). If the amount of Registrable Securities to be
underwritten has not been limited in accordance with the first sentence of this Section 2.01(f), CS&L and the holders of Common Stock or, if the Registrable Securities include securities other than Common Stock, the holders of
securities of the same class of those securities included in the Registrable Securities, in each case, other than the Holders (“Other Holders”), may include such securities for their own account or for the account of Other Holders
in such Registration if the underwriter(s) so agree and to the extent that, in the opinion of such underwriter(s), the inclusion of such additional amount will not adversely affect the offering of the Registrable Securities included in such

 Section 2.02 Piggyback Registrations. 

(a) Prior to the earlier to occur of the fifth anniversary of the Distribution Date or the date on which the Registrable Securities then held
by the Holder(s) represents less than 1% of CS&L’s then-issued and outstanding Common Stock (or, if the Registrable Securities include securities other than Common Stock, less than 1% of CS&L’s then-issued and outstanding
securities of the same class as the securities included in the Registrable Securities), if CS&L proposes to file a Registration Statement (other than a Shelf Registration) or a Prospectus supplement filed pursuant to a Shelf Registration
Statement under the Securities Act with respect to any offering of such securities for its own account and/or for the account of any Person (other than (i) a Registration under Section 2.01, (ii) a Registration pursuant to a
Registration Statement on Form S-8 or on Form S-4 or similar form that relates to a transaction subject to Rule 145 under the Securities Act, (iii) in connection with any dividend reinvestment or similar plan, (iv) for the sole purpose of
offering securities to another entity or its security holders in connection with the acquisition of assets or securities of such entity or any similar transaction or (v) a Registration in which the only Common Stock being registered is Common
Stock issuable upon conversion of debt securities that are also being registered) (each, a “CS&L Public Sale”), then, as soon as practicable, but in any event not less than 15 days prior to the proposed date of filing such
Registration Statement, CS&L shall give written notice of such proposed filing to each Holder, and such notice shall offer such Holders the opportunity to Register under such Registration Statement such number of Registrable Securities as each
such Holder may request in writing (each, a “Piggyback Registration”). Subject to Section 2.02(b) and Section 2.02(c), CS&L shall use its commercially reasonable efforts to include in a Registration
Statement with respect to a CS&L Public Sale all Registrable Securities that are requested to be included therein within five Business Days after the receipt of any such notice; provided, however, that 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, CS&L shall determine for any reason not to Register or to delay Registration of
the CS&L Public Sale, CS&L may, at its election, give written notice of such determination to each such Holder and, thereupon, (x) in the case of a determination not to Register, shall be relieved of its obligation to Register any
Registrable Securities in connection with such Registration, without prejudice, however, to the rights of any Holder to request that such Registration be effected as a Demand Registration under Section 2.01 and (y) in the case of a
determination to delay Registration, shall be permitted to delay Registering any Registrable Securities for the same period as the delay in Registering such other shares of Common Stock in the CS&L Public Sale. No Registration effected under
this Section 2.02 shall relieve CS&L of its obligation to effect any Demand Registration under Section 2.01. 

(b) In the case of any Underwritten Offering, each Holder shall have the right to withdraw such Holder’s request for inclusion of its
Registrable Securities in such Underwritten Offering pursuant to Section 2.02(a) at any time prior to the execution of an underwriting agreement with respect thereto by giving written notice to CS&L of such Holder’s request to
withdraw and, subject to the preceding clause, each Holder shall be permitted to withdraw all or part of such Holder’s Registrable Securities from a Piggyback Registration at any time prior to the effective date thereof. 

  
 11 

 (c) If the managing underwriter or underwriters of any proposed Underwritten Offering of a class
of Registrable Securities included in a Piggyback Registration informs CS&L and each Holder in writing that, in its or their opinion, the number of securities of such class that such Holder and any other Persons intend to include in such
offering exceeds the number that can be Sold in such offering without being reasonably likely to have an adverse effect on the price, timing or distribution of the securities offered or the market for the securities offered, then the securities to
be included in such Registration shall be (i) first, all securities of CS&L and any other Persons (other than CS&L’s executive officers and directors) for whom CS&L is effecting the Registration, as the case may be, proposes to
Sell, (ii) second, the number, if any, of Registrable Securities of such class that, in the opinion of such managing underwriter or underwriters, can be Sold without having such adverse effect, with such number to be allocated pro rata among
the Holders that have requested to participate in such Registration based on the relative number of Registrable Securities of such class requested by such Holder to be included in such Sale, (iii) third, the number of securities of executive
officers and directors of CS&L for whom CS&L is effecting the Registration, as the case may be, with such number to be allocated pro rata among the executive officers and directors and (iv) fourth, any other securities eligible for
inclusion in such Registration, allocated among the holders of such securities in such proportion as CS&L and those holders may agree. 

(d) After a Holder has been notified of its opportunity to include Registrable Securities in a Piggyback Registration, such Holder
(i) shall treat the Offering Confidential Information as confidential information, (ii) shall not use any Offering Confidential Information for any purpose other than to evaluate whether to include its Registrable Securities (or other
shares of Common Stock) in such Piggyback Registration, (iii) shall not trade while aware of such Offering Confidential Information if such information shall constitute material non-public information unless and until such information shall
become public or shall cease to be material, and (iv) shall not disclose any Offering Confidential Information to any Person other than such of its agents, employees, advisors and counsel as have a need to know such Offering Confidential
Information, and to cause such agents, employees, advisors and counsel to comply with the requirements of this Section 2.02(d); provided, that any such Holder may disclose Offering Confidential Information if such disclosure is
required by legal process, but such Holder shall cooperate with CS&L to limit the extent of such disclosure through protective order or otherwise, and to seek confidential treatment of the Offering Confidential Information. 

Section 2.03 Registration Procedures. 

(a) In connection with CS&L’s Registration obligations under Section 2.01 and Section 2.02, CS&L shall
use its reasonable best efforts to effect such Registration to permit the offer and Sale of such Registrable Securities in accordance with the intended method or methods of distribution thereof as expeditiously as reasonably practicable and, in
connection therewith, CS&L shall, and shall cause the members of the CS&L Group to: 
 (i) prepare and file the
required Registration Statement, including all exhibits and financial statements and, in the case of an Exchange Offer, any document required under Rule 425 or Rule 165 with respect to such Exchange Offer (collectively, the “Ancillary
Filings”) required under the Securities Act to be filed therewith, and before filing with the SEC a Registration 

  
 12 

 
Statement or Prospectus, or any amendments or supplements thereto, (A) furnish to the underwriters or dealer managers, if any, and to the Holders, copies of all documents prepared to be
filed, which documents shall be subject to the review and comment of such underwriters or dealer managers and such Holders and their respective counsel, and provide such underwriters or dealers managers, if any, and such Holders and their respective
counsel reasonable time to review and comment thereon and (B) not file with the SEC any Registration Statement or Prospectus or amendments or supplements thereto or any Ancillary Filing to which the Holders or the underwriters or dealer
managers, if any, shall reasonably object; 
 (ii) prepare and file with the SEC such amendments and post-effective
amendments to such Registration Statement and supplements to the Prospectus and any Ancillary Filing as may be reasonably requested by the participating Holders; 

(iii) promptly notify the participating Holders and the managing underwriters or dealer managers, if any, and, if requested,
confirm such advice in writing and provide copies of the relevant documents, as soon as reasonably practicable after notice thereof is received by any member of the CS&L Group (A) when the applicable Registration Statement or any amendment
thereto has been filed or becomes effective, the applicable Prospectus or any amendment or supplement to such Prospectus has been filed, or any Ancillary Filing has been filed, (B) of any comments (written or oral) by the SEC or any request
(written or oral) by the SEC or any other Governmental Authority for amendments or supplements to such Registration Statement, such Prospectus or any Ancillary Filing, or for any additional information, (C) of the issuance by the SEC of any
stop order suspending the effectiveness of such Registration Statement, any order preventing or suspending the use of any preliminary or final Prospectus or any Ancillary Filing, or the initiation or threatening of any proceedings for such purposes,
(D) if, at any time, the representations and warranties (written or oral) in any applicable underwriting agreement or dealer manager agreement cease to be true and correct in all material respects and (E) of the receipt by any member of
the CS&L Group of any notification with respect to the suspension of the qualification of the Registrable Securities for offering or Sale in any jurisdiction or the initiation or threatening of any proceeding for such purpose; 

(iv) (A) promptly notify each participating Holder and the managing underwriter(s) or dealer manager(s), if any, when CS&L
becomes aware of the occurrence of any event as a result of which the applicable Registration Statement, the Prospectus included in such Registration Statement (as then in effect) or any Ancillary Filing contains any untrue statement of a material
fact or omits to state a material fact necessary to make the statements therein (in the case of such Prospectus and any preliminary Prospectus, in light of the circumstances under which they were made) not misleading, or if for any other reason it
shall be necessary during such time period to amend or supplement such Registration Statement, Prospectus or any Ancillary Filing in order to 

  
 13 

 
comply with the Securities Act, and (B) in either case, as promptly as reasonably practicable thereafter, prepare and file with the SEC, and furnish without charge to each participating
Holder and the underwriter(s) or dealer manager(s), if any, an amendment or supplement to such Registration Statement, Prospectus or Ancillary Filing that will correct such statement or omission or effect such compliance; 

(v) use its reasonable best efforts to prevent or obtain the withdrawal of any stop order or other order suspending the use of
any preliminary or final Prospectus; 
 (vi) promptly (A) incorporate in a Prospectus supplement or post-effective
amendment such information as the managing underwriter(s) or dealer manager(s), if any, and the Holders agree should be included therein relating to the plan of distribution with respect to such Registrable Securities and (B) make all required
filings of such Prospectus supplement or post-effective amendment as soon as reasonably practicable after being notified of the matters to be incorporated in such Prospectus supplement or post-effective
amendment; 
 (vii) furnish to each participating Holder and each underwriter or dealer manager, if any, without charge, as
many conformed copies as such Holder or underwriter or dealer manager may reasonably request of the applicable Registration Statement and any amendment or post-effective amendment thereto, including financial statements and schedules, all documents
incorporated therein by reference and all exhibits (including those incorporated by reference); 
 (viii) deliver to each
participating Holder and each underwriter or dealer manager, if any, without charge, as many copies of the applicable Prospectus (including each preliminary Prospectus) and any amendment or supplement thereto as such Holder or underwriter or dealer
manager may reasonably request (it being understood that CS&L consents to the use of such Prospectus or any amendment or supplement thereto by each participating Holder and the underwriter(s) or dealer manager(s), if any, in connection with the
offering and Sale of the Registrable Securities covered by such Prospectus or any amendment or supplement thereto) and such other documents as such participating Holder or underwriter or dealer manager may reasonably request in order to facilitate
the Sale of the Registrable Securities by such Holder or underwriter or dealer manager; 
 (ix) on or prior to the date on
which the applicable Registration Statement is declared effective or becomes effective, use its reasonable best efforts to register or qualify, and cooperate with each participating Holder, the managing underwriter(s) or dealer manager(s), if any,
and their respective counsel, in connection with the registration or qualification of, such Registrable Securities for offer and Sale under the securities or “blue sky” laws of each state and other jurisdiction of the United States
as any participating Holder 

  
 14 

 
or managing underwriter(s) or dealer manager(s), if any, or their respective counsel reasonably request, and in any foreign jurisdiction mutually agreeable to CS&L and the participating
Holders, and do any and all other acts or things reasonably necessary or advisable to keep such registration or qualification in effect for so long as such Registration Statement remains in effect and so as to permit the continuance of offers and
Sales and dealings in such jurisdictions for so long as may be necessary to complete the distribution of the Registrable Securities covered by the Registration Statement; provided that CS&L will not be required to qualify generally to do
business in any jurisdiction where it is not then so qualified, to take any action which would subject it to taxation or general service of process in any such jurisdiction where it is not then so subject or conform its capitalization or the
composition of its assets at the time to the securities or blue sky laws of any such jurisdiction; 
 (x) in connection with
any Sale of Registrable Securities that will result in such securities no longer being Registrable Securities, cooperate with each participating Holder and the managing underwriter(s) or dealer manager(s), if any, to (A) if the Registrable
Securities are certificated, facilitate the timely preparation and delivery of certificates representing Registrable Securities to be Sold and not bearing any restrictive Securities Act legends and (B) register such Registrable Securities in
such denominations and such names as such participating Holder or the underwriter(s) or dealer manager(s), if any, may request at least two Business Days prior to such Sale of Registrable Securities; provided that CS&L may satisfy its
obligations hereunder without issuing physical stock certificates through the use of the Depository Trust Company’s Direct Registration System; 

(xi) cooperate and assist in any filings required to be made with the Financial Industry Regulatory Authority Inc. (or any
successor organization) and each securities exchange, if any, on which any of CS&L’s securities are then listed or quoted and on each inter-dealer quotation system or trading market on which any of CS&L’s securities are then
quoted, and in the performance of any due diligence investigation by any underwriter or dealer manager (including any “qualified independent underwriter”) that is required to be retained in accordance with the rules and regulations
of each such exchange, and use its reasonable best efforts to cause the Registrable Securities covered by the applicable Registration Statement to be registered with or approved by such other Governmental Authorities as may be necessary to enable
the seller or sellers thereof or the underwriter(s) or dealer manager(s), if any, to consummate the Sale of such Registrable Securities; 

(xii) not later than the effective date of the applicable Registration Statement, provide a CUSIP number for all Registrable
Securities and provide the applicable transfer agent with printed certificates for the Registrable Securities which are in a form eligible for deposit with the Depository Trust Company; provided, that CS&L may satisfy its obligations
hereunder without issuing physical stock certificates through the use of the Depository Trust Company’s Direct Registration System; 

  
 15 

 (xiii) obtain for delivery to and addressed to each participating Holder and to
the underwriter(s) or dealer manager(s), if any, opinions from the general counsel of CS&L, dated the effective date of the Registration Statement or, in the event of an Underwritten Offering, the date of the closing under the underwriting
agreement or, in the event of an Exchange Offer, the date of the closing under the dealer manager agreement or similar agreement or otherwise, and in each such case in customary form and content for the type of Underwritten Offering or Exchange
Offer, as applicable; 
 (xiv) in the case of an Underwritten Offering or Exchange Offer, obtain for delivery to and
addressed to CS&L and the managing underwriter(s) or dealer manager(s), if any, and, to the extent requested, each participating Holder, a comfort letter from CS&L’s independent registered public accounting firm in customary form and
content for the type of Underwritten Offering or Exchange Offer, dated the date of execution of the underwriting agreement or dealer manager agreement or, if none, the date of commencement of the Exchange Offer, and brought down to the closing,
whether under the underwriting agreement or dealer manager agreement, if applicable, or otherwise; 
 (xv) in the case of an
Exchange Offer that does not involve a dealer manager, provide to each participating Holder such customary written representations and warranties or other covenants or agreements as may be requested by any participating Holder comparable to those
that would be included in an underwriting or dealer manager agreement; 
 (xvi) use its reasonable best efforts to comply
with all applicable rules and regulations of the SEC and make generally available to its security holders, as soon as reasonably practicable, but in any event no later than 90 days, after the end of the 12-month period beginning with the first day
of CS&L’s first quarter commencing after the effective date of the applicable Registration Statement, an earnings statement satisfying the provisions of Section 11(a) of the Securities Act and covering the period of at least 12 months,
but not more than 18 months, beginning with the first month after the effective date of the Registration Statement; 

(xvii) provide and cause to be maintained a transfer agent and registrar for all Registrable Securities covered by the
applicable Registration Statement from and after a date not later than the effective date of such Registration Statement; 

(xviii) cause all Registrable Securities covered by the applicable Registration Statement to be listed on each securities
exchange on which any of CS&L’s securities are then listed or quoted and on each inter-dealer quotation system or trading market on which any of CS&L’s securities are then quoted; 

  
 16 

 (xix) provide (A) each Holder participating in the Registration,
(B) the underwriters (which term, for purposes of this Agreement, shall include any Person deemed to be an underwriter within the meaning of Section 2(a)(11) of the Securities Act), if any, of the Registrable Securities to be registered,
(C) the Sale or placement agent therefor, if any, (D) the dealer manager therefor, if any, (E) counsel for such Holder, underwriters, agent, or dealer manager and (F) any attorney, accountant or other agent or representative
retained by such Holder or any such underwriter or dealer manager, as selected by such Holder, in each case, the opportunity to participate in the preparation of such Registration Statement, each Prospectus included therein or filed with the SEC,
and each amendment or supplement thereto; and for a reasonable period prior to the filing of such Registration Statement, upon execution of a customary confidentiality agreement, make available for inspection upon reasonable notice at reasonable
times and for reasonable periods, by the parties referred to in clauses (A) through (F) above, all pertinent financial and other records, pertinent corporate and other documents and properties of the CS&L Group that are available to
CS&L, and cause all of the CS&L Group’s officers, directors and employees and the independent public accountants who have certified its financial statements to make themselves available at reasonable times and for reasonable periods to
discuss the business of CS&L and to supply all information available to CS&L reasonably requested by any such Person in connection with such Registration Statement as shall be necessary to enable them to exercise their due diligence or other
responsibility, subject to the foregoing; provided, that in no event shall any member of the CS&L Group be required to make available any information which the Board determines in good faith to be competitively sensitive or confidential.
The recipients of such information shall coordinate with one another so that the inspection permitted hereunder will not unnecessarily interfere with the CS&L Group’s conduct of business. Each Holder agrees that information obtained by it
as a result of such inspections shall be deemed confidential and shall not be used by it as the basis for any market transactions in the securities of CS&L or its Affiliates unless and until such information is made generally available to the
public by CS&L or such Affiliate or for any reason not related to the Registration of Registrable Securities; 
 (xx) in
the case of an Underwritten Offering or Exchange Offer registering 20% or more of the original number of Retained Shares (as adjusted pursuant to Section 4.12), cause the senior executive officers of CS&L to participate at reasonable times
and for reasonable periods in the customary “road show” presentations that may be reasonably requested by the managing underwriter(s) or dealer manager(s), if any, and otherwise to facilitate, cooperate with, and participate in each
proposed offering contemplated herein and customary selling efforts related thereto; 

  
 17 

 (xxi) comply with all requirements of the Securities Act, Exchange Act and other
applicable laws, rules and regulations, as well as all applicable stock exchange rules; and 
 (xxii) take all other
customary steps reasonably necessary or advisable to effect the Registration and distribution of the Registrable Securities contemplated hereby. 

(b) As a condition precedent to any Registration hereunder, CS&L may require each Holder as to which any Registration is being effected
to furnish to CS&L such information regarding the distribution of such securities and such other information relating to such Holder, its ownership of Registrable Securities and other matters as CS&L may from time to time reasonably request
in writing. Each such Holder agrees to furnish such information to CS&L and to cooperate with CS&L as reasonably necessary to enable CS&L to comply with the provisions of this Agreement. If a Holder fails to promptly provide the
requested information after prior written notice of such request and the requested information is required by applicable law to be included in the Registration Statement, CS&L shall be entitled to refuse to include for registration such
Holder’s Registrable Securities or other shares of Common Stock in the Registration Statement. 
 (c) Each Holder shall, as promptly
as reasonably practicable, notify CS&L, at any time when a Prospectus is required to be delivered (or deemed delivered) under the Securities Act, of the occurrence of an event, of which such Holder has knowledge, relating to such Holder or its
Sale of Registrable Securities thereunder requiring the preparation of a supplement or amendment to such Prospectus so that, as thereafter delivered (or deemed delivered) to the purchasers of such Registrable Securities, such Prospectus will not
contain an untrue statement of a material fact or omit to state any material fact required to be stated therein or necessary to make the statements therein, in light of the circumstances under which they are made, not misleading. 

(d) Windstream agrees (on behalf of itself and each member of the WHI Group), and any other Holder agrees by acquisition of such Registrable
Securities, that, upon receipt of any written notice from CS&L of the occurrence of any event of the kind described in Section 2.03(a)(iv), such Holder will treat such notice as Offering Confidential Information and comply with
Section 2.02(d), regardless of the nature of the Registration, and will forthwith discontinue Sale of Registrable Securities pursuant to such Registration Statement until such Holder’s receipt of the copies of the supplemented or amended
Prospectus contemplated by Section 2.03(a)(iv), or until such Holder is advised in writing by CS&L that the use of the Prospectus may be resumed. In the event CS&L shall give any such notice, the period during which the
applicable Registration Statement is required to be maintained effective shall be extended by the number of days during the period from and including the date of the giving of such notice through the date when each seller of Registrable Securities
covered by such Registration Statement either receives the copies of the supplemented or amended Prospectus contemplated by Section 2.03(a)(iv) or is advised in writing by CS&L that the use of the Prospectus may be resumed. 

  
 18 

 Section 2.04 Underwritten Offerings or Exchange Offers. 

(a) If requested by the managing underwriter(s) for any Underwritten Offering or dealer manager(s) for any Exchange Offer that is requested by
Holders pursuant to a Demand Registration under Section 2.01, CS&L shall enter into an underwriting agreement or dealer manager agreement, as applicable, with such underwriter(s) or dealer manager(s) for such offering, such agreement
to be reasonably satisfactory in substance and form to CS&L and the underwriter(s) or dealer manager(s) and, if the WHI Group is a participating Holder, to the WHI Group. Such agreement shall contain such representations and warranties by
CS&L and such other terms as are generally prevailing in agreements of that type. Each Holder with Registrable Securities to be included in any Underwritten Offering or Exchange Offer by such underwriter(s) or dealer manager(s) shall enter into
such underwriting agreement or dealer manager agreement at the request of CS&L, which agreement shall contain such reasonable representations and warranties by the Holder and such other reasonable terms as are generally prevailing in agreements
of that type. 
 (b) In the event of a CS&L Public Sale involving an offering of Common Stock or other equity securities of CS&L in
an Underwritten Offering (whether in a Demand Registration or a Piggyback Registration, whether or not the Holders participate therein), the Holders hereby agree, and, in the event of a CS&L Public Sale of Common Stock or other equity securities
of CS&L in an Underwritten Offering or an Exchange Offer, CS&L shall agree, and it shall cause its executive officers and directors to agree, if requested by the managing underwriter or underwriters in such Underwritten Offering or by the
Holder or the dealer manager or dealer managers, in an Exchange Offer, not to effect any Sale or distribution (including any offer to Sell, contract to Sell, short Sale or any option to purchase) of any securities (except, in each case, as part of
the applicable Registration, if permitted hereunder) that are of the same type as those being Registered in connection with such public offering and Sale, or any securities convertible into or exchangeable or exercisable for such securities, during
the period beginning five days before, and ending 90 days (or such lesser period as may be permitted by CS&L or the participating Holder(s), as applicable, or such managing underwriter or underwriters) after, the effective date of the
Registration Statement filed in connection with such Registration (or, if later, the date of the Prospectus), to the extent requested by such selling Person or the managing underwriter or underwriters or dealer manager or dealer managers, subject to
such exceptions as are customarily provided in covenants of this type. The participating Holders and CS&L, as applicable, also agree to execute an agreement evidencing the restrictions in this Section 2.04(b) in customary form, which
form is reasonably satisfactory to CS&L or the participating Holder(s), as applicable, and the underwriter(s) or dealer manager(s), as applicable; provided that such restrictions may be included in the underwriting agreement or dealer
manager agreement, if applicable. CS&L may impose stop-transfer instructions with respect to the securities subject to the foregoing restriction until the end of the required stand-off period. 

(c) No Holder may participate in any Underwritten Offering or Exchange Offer hereunder unless such Holder (i) agrees to Sell such
Holder’s securities on the basis provided in any underwriting arrangements or dealer manager agreements approved by CS&L or other Persons entitled to approve such arrangements and (ii) completes and executes all questionnaires, powers
of attorney, indemnities, underwriting agreements, dealer manager agreements and other documents reasonably required under the terms of such underwriting arrangements or dealer manager agreements or this Agreement. 

  
 19 

 Section 2.05 Registration Rights Agreement with Participating Banks. 

If one or more members of the WHI Group decides to engage in a Private Debt Exchange with one or more Participating Banks, CS&L shall enter into a
registration rights agreement with the Participating Banks in connection with such Private Debt Exchange on terms and conditions consistent with this Agreement providing any such Participating Bank with Registration-related right and obligations
consistent with those provided to the WHI Group pursuant to this Agreement (other than the voting provisions contained in Article III hereof) and reasonably satisfactory to CS&L and the WHI Group. Unless and until such additional
registration rights agreement is entered into by CS&L and a Participating Bank, such Participating Bank shall be entitled to the rights of a Transferee under this Agreement. Each exercise of rights to Demand Registration made pursuant to any
such registration rights agreement entered into pursuant to this Section 2.05, or pursuant to any exercise of such rights by a Participating Bank in its capacity as a Transferee, shall count as a Demand Registration for purposes of
Section 2.01(b). 
 Section 2.06 Registration Expenses Paid by CS&L. 

In the case of any Registration of Registrable Securities required pursuant to this Agreement, CS&L shall pay all Registration Expenses regardless of
whether the Registration Statement becomes effective; provided, however, that CS&L shall not be required to pay for any expenses of any Registration begun pursuant to Section 2.01 if the Demand Registration request is
subsequently withdrawn at the request of the Holders of a majority of the Registrable Securities to be Registered (in which case all participating Holders shall bear such expenses pro rata in accordance with the number of Registrable Securities
requested to be registered by each Holder), unless the Holders of a majority of the Registrable Securities agree to forfeit their right to one Demand Registration to which they have the right pursuant to Section 2.01(b). 

Section 2.07 Indemnification. 

(a) CS&L agrees to indemnify and hold harmless, to the full extent permitted by law, each Holder whose shares are included in a
Registration Statement, such Holder’s Affiliates and their respective officers, directors, agents, advisors, employees and each Person, if any, who controls (within the meaning of the Securities Act or the Exchange Act) such Holder, from and
against any and all losses, claims, damages, liabilities (or actions or proceedings in respect thereof, whether or not such indemnified party is a party thereto) and expenses, joint or several (including reasonable costs of investigation and legal
expenses) (each, a “Loss” and collectively “Losses”) arising out of or based upon (i) any untrue or alleged untrue statement of a material fact contained or incorporated by reference in any Registration
Statement under which the offering and Sale of such Registrable Securities was Registered under the Securities Act (including any final or preliminary Prospectus contained therein or any amendment thereof or supplement thereto or any documents
incorporated by reference therein), or any such statement made in any free writing prospectus (as defined in Rule 405 under the Securities Act) that CS&L has filed or is required to file pursuant to Rule 433(d) of the Securities Act or any
Ancillary Filing, (ii) any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein (in the case of a Prospectus, preliminary Prospectus or free writing prospectus,
in light of the circumstances under 

  
 20 

 
which they were made) not misleading; provided, that with respect to any untrue statement or omission or alleged untrue statement or omission made in any Prospectus, the indemnity
agreement contained in this paragraph shall not apply to the extent that any such liability results from or arises out of (A) the fact that a current copy of the Prospectus was not sent or given to the Person asserting any such liability at or
prior to the written confirmation of the Sale of the Registrable Securities concerned to such Person if it is determined by a court of competent jurisdiction in a final and non-appealable judgment that CS&L has provided such Prospectus and it
was the responsibility of such Holder or its agents to provide such Person with a current copy of the Prospectus and such current copy of the Prospectus would have cured the defect giving rise to such liability, (B) the use of any Prospectus by
or on behalf of any Holder after CS&L has notified such Person (x) that such Prospectus contains or incorporates by reference 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, in the light of the circumstances under which they were made, not misleading, (y) that a stop order has been issued by the SEC with respect to a Registration Statement or (z) that a Disadvantageous
Condition exists, or (C) information furnished in writing by such Holder or on such Holder’s behalf, in either case expressly for use in such Registration Statement, Prospectus, free writing prospectus or Ancillary Filing relating to such
Holder’s Registrable Securities. This indemnity shall be in addition to any liability CS&L may otherwise have, including under the Separation and Distribution Agreement. Such indemnity shall remain in full force and effect regardless of any
investigation made by or on behalf of such Holder or any indemnified party and shall survive the Sale of such securities by such Holder. 

(b) Each participating Holder whose Registrable Securities are included in a Registration Statement agrees (severally and not jointly) to
indemnify and hold harmless, to the full extent permitted by law, CS&L, its directors, officers, agents, advisors, employees and each Person, if any, who controls (within the meaning of the Securities Act and the Exchange Act) CS&L from and
against any and all Losses (i) arising out of or based upon information furnished in writing by such Holder or on such Holder’s behalf to CS&L, in either case expressly for use in a Registration Statement, Prospectus, free writing
prospectus or Ancillary Filing relating to such Holder’s Registrable Securities or (ii) arising out of or based upon (A) the fact that a current copy of the Prospectus was not sent or given to the Person asserting any such liability
at or prior to the written confirmation of the Sale of the Registrable Securities concerned to such Person if it is determined by a court of competent jurisdiction in a final and non-appealable judgment that it was the responsibility of such Holder
or its agent to provide such Person with a current copy of the Prospectus and such current copy of the Prospectus would have cured the defect giving rise to such liability, or (B) the use of any Prospectus by or on behalf of any Holder after
CS&L has notified such Person (x) that such Prospectus contains or incorporates by reference 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,
in the light of the circumstances under which they were made, not misleading, (y) that a stop order has been issued by the SEC with respect to a Registration Statement or (z) that a Disadvantageous Condition exists. This indemnity shall be
in addition to any liability the participating Holder may otherwise have, including under the Separation and Distribution Agreement. In no event shall the liability of any participating Holder hereunder be greater in amount than the dollar amount of
the net proceeds received by such holder under the Sale of the Registrable Securities giving rise to such indemnification obligation. Such indemnity shall remain in full force and effect regardless of any investigation made by or on behalf of
CS&L or any indemnified party. 

  
 21 

 (c) Any claim or action with respect to which a party (an “Indemnifying Party”)
may be obligated to provide indemnification to any Person entitled to indemnification hereunder (an “Indemnitee”) shall be subject to the procedures for indemnification set forth in Section
[—] of the Separation and Distribution Agreement. 
 (d) If for any reason the
indemnification provided for in Section 2.07(a) or Section 2.07(b) is unavailable to an Indemnitee or insufficient to hold it harmless as contemplated by Section 2.07(a) or Section 2.07(b), then the
Indemnifying Party shall contribute to the amount paid or payable by the Indemnitee as a result of such Loss in such proportion as is appropriate to reflect the relative fault of the Indemnifying Party on the one hand and the Indemnitee on the other
hand. The relative fault shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the
Indemnifying Party or the Indemnitee and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such untrue statement or omission. For the avoidance of doubt, the establishment of such relative
fault, and any disagreements or disputes relating thereto, shall be subject to Section 4.03. Notwithstanding anything in this Section 2.07(d) to the contrary, no Indemnifying Party (other than CS&L) shall be required
pursuant to this Section 2.07(d) to contribute any amount in excess of the amount by which the net proceeds received by such Indemnifying Party from the Sale of Registrable Securities in the offering to which the Losses of the
Indemnitees relate (before deducting expenses, if any) exceeds the amount of any damages which such Indemnifying Party has otherwise been required to pay by reason of such untrue statement or omission. The parties hereto agree that it would not be
just and equitable if contribution pursuant to this Section 2.07(d) were determined by pro rata allocation or by any other method of allocation that does not take account of the equitable considerations referred to in this
Section 2.07(d). 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.
The amount paid or payable by an Indemnitee hereunder shall be deemed to include, for purposes of this Section 2.07(d), any legal or other expenses reasonably incurred by such Indemnitee in connection with investigating, preparing to
defend or defending against or appearing as a third party witness in respect of, or otherwise incurred in connection with, any such loss, claim, damage, expense, liability, action, investigation or proceeding. If indemnification is available under
this Section 2.07, the Indemnifying Parties shall indemnify each Indemnitee to the full extent provided in Section 2.07(a) and Section 2.07(b) without regard to the relative fault of said Indemnifying Parties or
Indemnitee. Any Holders’ obligations to contribute pursuant to this Section 2.07(d) are several and not joint. 

Section 2.08 Reporting Requirements; Rule 144. 

Until the earlier of (a) the expiration or termination of this Agreement in accordance with its terms and (b) the date upon which the WHI Group
ceases to own any Registrable Securities, CS&L shall use its commercially reasonable efforts to be and remain in compliance with the periodic filing requirements imposed under the SEC’s rules and regulations, including the

  
 22 

 
Exchange Act, and any other applicable laws or rules, and thereafter shall timely file such information, documents and reports as the SEC may require or prescribe under Sections 13, 14 and 15(d),
as applicable, of the Exchange Act in order to enable the WHI Group to Sell Registrable Securities without registration under the Securities Act consistent with the exemptions from registration under the Securities Act provided by (i) Rule 144
or Regulation S under the Securities Act, as amended from time to time, or (ii) any similar SEC rule or regulation then in effect. From and after the date hereof through the earlier of the expiration or termination of this Agreement in
accordance with its terms and the date upon which the WHI Group ceases to own any Registrable Securities, CS&L shall forthwith upon request furnish any Holder (x) a written statement by CS&L as to whether it has complied with such
requirements and, if not, the specifics thereof, (y) a copy of the most recent annual or quarterly report of CS&L, and (z) such other reports and documents filed by CS&L with the SEC, as such Holder may reasonably request in
availing itself of an exemption for the offering and Sale of Registrable Securities without registration under the Securities Act. 

Section 2.09 Registration Rights Covenant. 

CS&L covenants that it will not, and it will cause the members of the CS&L Group not to, grant any right of registration under the Securities Act
relating to any of its shares of Common Stock or other securities to any Person other than pursuant to this Agreement, unless the rights so granted to another Person do not limit or restrict the right of the Holder(s) hereunder.

such securities to no longer be deemed to be Registrable Securities under this Agreement.

 In addition to the actions specifically provided for elsewhere in this Agreement, each of the parties hereto shall use its commercially reasonable efforts
to take, or cause to be taken, all actions, and to do, or cause to be done, all things reasonably necessary, proper or advisable on its part under applicable laws, regulations and agreements, to consummate and make effective the transactions
