Section 8. Transfer. The H&F Holders may Transfer Partnership CVRs only in accordance with this Section 8 and any purported Transfer of a Partnership CVR other than in accordance with this Section 8 shall be void. Upon the Transfer on or prior to the Test Date by an H&F Holder of Preferred Units to any Person in accordance with the Partnership Agreement, an equal number of Partnership CVRs shall automatically be deemed transferred to the same Person and such Person shall be deemed to have become a party to this Agreement and succeeded to the rights and obligations of such H&F Holder in respect of the Partnership CVRs so Transferred. For the avoidance of doubt, the Partnership Agreement permits the Original H&F Holders (as defined therein) to Transfer Preferred Units to their Affiliates (as defined therein). Upon any such Transfer of Preferred Units by an Original H&F Holder to an Affiliate an equal number of Partnership CVRs shall automatically be deemed Transferred to the Affiliate and such Affiliate shall be deemed to have become a party to this Agreement and succeeded to the rights and obligations of such Original H&F Holder in respect of the Partnership CVRs so Transferred.

Adjustment. Upon any Stock Subdivision or Combination, the number of Partnership CVRs held by each Holder shall automatically be adjusted such that the Holder’s Number of CVRs shall increase or decrease in proportion to the increase or decrease in the number of outstanding shares of Class A Common Stock as a result of such Stock Subdivision or Combination.

Section 10. No Rights as Partners; Limitation of Liability. Neither this Agreement nor the Partnership CVRs entitle the Holders to any voting rights or other rights as partners of Holdings.
