Section 2.2. Amendments to Section 3.4(c) of the A&R Investors Shareholders Agreement. Section 3.4(c) of the A&R Investors Shareholders Agreement is hereby amended and restated in its entirety as follows:

(c) Transfers During the Post-IPO Transfer Restriction Periods. Without limiting Section 3.1 or Section 3.5 and subject in all cases to Section 3.4(b), during the Post-IPO Transfer Restriction Periods, each of the Key Management Investors and their Permitted Transferees shall not transfer any Securities to any Person, except transfers of Transferable Shares (A) to Permitted Transferees pursuant to Section 3.2, (B) upon receipt of the prior written consent of the Silver Lake Investors and (C) as of the date of any proposed transfer, in accordance with such Key Management Investor’s Applicable Transfer Cap as of such transfer, as calculated by the Company in accordance with Section 3.4(c)(i)Section 2.2(c)(i) below. For the avoidance of doubt, the transfer restrictions set forth in this Section 3.4(c) shall apply to the exercise of such Key Management Investor’s rights in any registered offerings during the Post-IPO Transfer Restriction Periods under the Registration Rights Agreement.

(i) To the extent any Key Management Investor or his Permitted Transferee desires to transfer any Transferable Shares to any Person (other than (x) a Permitted Transferee pursuant to Section 3.2 or (y) transfers upon receipt of the prior written consent of the Silver Lake Investors) or implement a Non-Discretionary Sale Program (or increase the number of Transferrable Shares permitted to be sold thereunder), such Key Management Investor or his Permitted Transferee, as applicable, shall provide written notice (a “Post-IPO Transfer Notice”) of such action to the Company and the Silver Lake Investors at least three (3) Business Days prior thereto, setting forth, as applicable, (i) the number of Transferable Shares proposed to be transferred or covered by such Non-Discretionary Sale Program and (ii) the identity of the proposed transferee, if known, and the manner of disposition contemplated for such proposed transfer or the identity of the broker-dealer that will be establishing such Non-Discretionary Sale Program. Within three (3) Business Days following receipt of such Post-IPO Transfer Notice, the Company shall provide written notice to such Key Management Investor or his Permitted Transferee, as applicable, and the Silver Lake Investors setting forth the Applicable Transfer Cap for such Key Management Investor or his Permitted Transferee as of the date of delivery of such Post-IPO Transfer Notice, provided that such Key Management Investor or his Permitted Transferee, as applicable, shall provide the Company with all information reasonably requested by the Company in order to calculate such Applicable Transfer Cap.

(ii) Notwithstanding the foregoing, if a Key Management Investor or his Permitted Transferee wishes to transfer a number of Transferrable Shares during the Second Period or Third Period and the Applicable Transfer Cap for such Key Management Investor or his Permitted Transferee is in excess of such Key Management Investor’s or his Permitted Transferee’s Applicable Transfer Cap if the provisos in the definition of each of Second Period Cap and Third Period Cap (as applicable) were disregarded, then any such excess Transferrable Shares must be transferred pursuant to a Non-Discretionary Sale Program established in accordance with Section 3.4(c)(iii).

(iii) Each Key Management Investor or his Permitted Transferee may establish a Non-Discretionary Sale Program for the sale of Transferable Shares owned by such Key Management Investor and his Permitted Transferees (A) within thirty (30) days after the beginning of the Second Period to cover sales during the Second Period (any such instituted program, a “Second Period Non-Discretionary Sale Program”), and (B) within thirty (30) days after the beginning of the Third Period to cover sales of Transferable Shares within the Third Period (any such instituted program, a “Third Period Non-Discretionary Sale Program”); provided, that if the trading window is closed during either such thirty (30) day period, following the opening of the trading window, the applicable thirty (30) day period shall be extended by the number of days the trading window was closed during such period; and provided, further, that any such Second Period Non-Discretionary Sale Program or Third Period Non-Discretionary Sale Program must provide that the minimum price for sales of Transferable Shares pursuant to such program must exceed one-hundred and five percent (105%) of the closing price per Share on the Trading Day immediately prior to the effective date of institution of any such Second Period Non-Discretionary Sale Program or Third Period Non-Discretionary Sale Program, as applicable; provided, however, that notwithstanding the foregoing, a Key Management Investor or his Permitted Transferees may establish a Non-Discretionary Sale Program for the sale of Transferrable Shares at any time during an open trading window (which, for this purpose, shall include the period prior to the Initial Public Offering) for any or all of his Transferrable Shares as long as such Non-Discretionary Sale Program does not permit the sale of any such shares other than as permitted by this Agreement; and in such case the minimum price for sales of Transferrable Shares pursuant to such program must exceed one-hundred and five percent (105%) of the closing price per Share on the Trading Day immediately prior to the effective date of such plan. Each Non-Discretionary Sale Program shall not permit the transfer of a number of Transferrable Shares in excess of the Applicable Transfer Cap for such Key Management Investor and his Permitted Transferees from time to time, but such cap shall never be less than the number of Transferable Shares permitted under the Applicable Transfer Cap at the time of creation of the Non-Discretionary Sales Program. Notwithstanding the foregoing, a Key Management Investor or his Permitted Transferee may amend any Non-Discretionary Sales Program to provide for sales of excess Transferable Shares as required by Section 3.4(c)(ii), but in all cases subject to the Applicable Transfer Cap for such Key Management Investor and his Permitted Transferee. For the avoidance of doubt, in no event shall a Key Management Investor or his Permitted Transferee be permitted to sell (whether or not pursuant to a Non-Discretionary Sales Program and whether or not in one or more transactions) an amount in excess of the Applicable Transfer Cap of such Key Management Investor.
