(ii) Notwithstanding any other provision of this Agreement to the contrary, if there is a Final Determination that a Distribution Disqualification has occurred, then, to the extent that the Distribution Disqualification results from any Disqualifying Action taken after the Distribution Date by CS&L or any other member of the CS&L Group, CS&L shall indemnify, defend and hold harmless the WHI Group from and against any and all (A) Distribution Taxes, (B) accounting, legal and other professional fees and court costs incurred in connection with such Taxes (other than such costs incurred in the joint defense of a Third-Party Claim, which costs are subject to Section 5.4 below) and (C) Taxes resulting from indemnification payments hereunder incurred by the WHI Group.

If and to the extent that the CS&L Group is not permitted by applicable law to forego such carryback and requests in writing that WHI obtain a refund with respect to such carryback, then (a) WHI shall use commercially reasonable efforts to obtain a refund with respect to such carryback (including by filing an amended Tax Return) and (b) to the extent that WHI receives a refund of Taxes (including interest received thereon) attributable to such carryback, WHI shall pay such refund to CS&L.

Notwithstanding the foregoing:

(i) CS&L may issue additional shares of common stock of CS&L to a person in a transaction to which section 83 or section 421(a) or (b) of the Code applies (or options to acquire stock in such a transaction) in connection with the person’s performance of services as an employee, director or independent contractor of any member of the CS&L Group or any other person that is related to CS&L under section 355(d)(7)(A) of the Code or a corporation the assets of which CS&L or a member of the CS&L Group acquires in a reorganization under section 368 of the Code, provided that such stock is not excessive by reference to the services performed by such person and such person or a coordinating group of which the person is a member will not be a controlling shareholder or a ten-percent shareholder of CS&L (within the meaning of sections 1.355-7(h)(3) and (8) of the Treasury Regulations) immediately after the issuance of such common stock; and

(ii) CS&L may issue additional shares of common stock of CS&L to a retirement plan of CS&L or any other person that is treated as the same employer as CS&L under section 414(b), (c), (m), or (o) of the Code that qualifies under section 401(a) or 403(a) of the Code, provided that the stock acquired by all of the qualified plans of CS&L and such other persons during the four-year period beginning two years before the Distribution Date does not, in the aggregate, represent more than ten percent of the total combined voting power of all classes of stock of CS&L entitled to vote or more than ten percent of the total value of shares of all classes of stock of CS&L.

13

(d) Until the expiration of the Restricted Period, CS&L shall continue and cause to be continued the active conduct (as defined in section 355(b)(2) of the Code and the Treasury Regulations promulgated thereunder) of the Consumer CLEC Business, taking into account section 355(b)(3) of the Code.

(e) Until the expiration of the Restricted Period, CS&L shall not voluntarily dissolve, liquidate, merge or consolidate with any other person, unless, in the case of a merger or consolidation, CS&L is the survivor of the merger or consolidation.

(f) Until the expiration of the Restricted Period, CS&L shall not redeem or otherwise repurchase (directly or through an Affiliate) any stock, or rights to acquire stock, except to the extent such repurchases satisfy section 4.05(1)(b) of Revenue Procedure 96-30 (as in effect prior to the amendment of such Revenue Procedure by Revenue Procedure 2003-48 and Revenue Procedure 2013-32).

(g) Neither CS&L nor any member of the CS&L Group (including the Operating Partnership) shall take any action with respect to the CS&L Debt Securities that might result in their failing to qualify as “securities” of CS&L, within the meaning of section 361, for purposes of the Internal Distribution and the Debt Exchange.

(h) Notwithstanding the foregoing, the provisions of this Section 3.2 shall not prohibit CS&L or any member of the CS&L Group from implementing any action or transaction (including a Potential Disqualifying Action) if (i) the IRS has granted a favorable ruling to WHI or CS&L that such action would not alter the Tax-Free Status of the Transactions, (ii) CS&L has delivered to WHI an Unqualified Tax Opinion, in form and substance reasonably acceptable to WHI, with respect to such action or transaction, or (iii) WHI has waived in writing the requirement to obtain such ruling or Unqualified Tax Opinion with respect to such action or transaction. Within 10 Business Days of the receipt by WHI of a draft of an Unqualified Tax Opinion, WHI shall inform CS&L in writing of whether such Unqualified Tax Opinion is reasonably acceptable to it and, to the extent unacceptable, shall inform CS&L with reasonable specificity of the reasons therefor. If CS&L notifies WHI that it desires to seek a ruling from the IRS or an Unqualified Tax Opinion with respect to such an action or transaction, WHI shall cooperate with CS&L and use its commercially reasonable efforts to assist CS&L in obtaining such a ruling from the IRS or an Unqualified Tax Opinion. CS&L shall reimburse WHI for all reasonable out-of-pocket costs and expenses incurred by the WHI Group in assisting CS&L in obtaining a ruling or Unqualified Tax Opinion within ten (10) days after receiving an invoice from WHI therefor.

PAYMENTS

If the receipt or accrual of any such payment that is an indemnification payment results in Taxable income (including an increase in the amount of any gain or other income recognized on the Distributions) to the recipient thereof, such payment shall be increased so that, after the payment of any Taxes with respect to the payment, the recipient thereof shall have realized the same net amount it would have realized had the payment not resulted in Taxable income.

Section 4.3 Notice. The Parties shall give each other prompt written notice of any payment that may be due to the provider of such notice under this Agreement.

WHI and CS&L shall exercise their rights to jointly control the defense of any such Tax Contest solely for the purpose of defeating such Tax Contest.
