TRANSFERS 2.1 LIMITATIONS ON TRANSFER. Without the prior written consent of the Blackstone Representative, BACI may not Transfer any Ordinary Shares prior to the earlier of (x) the fifth (5th) anniversary of the date hereof and (y) the six (6) month anniversary of the Initial Public Offering (or such shorter period as the underwriters for such Initial Public Offering shall require of either the Blackstone Entities or BACI) (the "INITIAL SHARE HOLDING PERIOD") other than (1) to a BACI Affiliate Transferee in accordance with the provisions of Section 2.2, (2) to one or more Blackstone Entities pursuant to Section 2.3, (3) as a Tagging Shareholder pursuant to Section 2.4, (4) as a Drag-Along Shareholder pursuant to Section 2.5 or (5) pursuant to the rights set forth in the Registration Rights Agreement. Without limiting BACI's rights to transfer to a BACI Affiliate Transferee pursuant to clause (1) of the preceding sentence, in the event of any proposed Transfer by BACI of all of the Ordinary Shares held by BACI to a Transferee that is an institutional investor of national reputation and that executes a BACI Permitted Assign Agreement, which proposed Transfer is subject to the rights set forth in Section 2.3 below, such consent of the Blackstone Representative shall not be unreasonably withheld or delayed. After the Initial Share Holding Period, BACI may Transfer its Ordinary Shares only in accordance with, and subject to the applicable provisions of, this Article II or pursuant to the rights set forth in the Registration Rights Agreement. Any Transferee of BACI prior to the six (6) month anniversary of the Initial Public Offering (or such shorter period as the underwriters for such Initial Public Offering shall require of either the Blackstone Entities or BACI) must qualify as a BACI Permitted Assign. (b) In the event of any purported Transfer by BACI of any Ordinary Shares in violation of the provisions of this Agreement, such purported Transfer will be void and of no effect and the Company will not give effect to such Transfer. (c) Each certificate representing Ordinary Shares held by any Shareholder will bear a legend substantially to the following effect: "THE SHARES REPRESENTED BY THIS CERTIFICATE ARE SUBJECT TO A SHAREHOLDERS' AGREEMENT AMONG Blackstone Crystal Holdings Capital Partners (Cayman) IV Ltd. AND THE SHAREHOLDERS PARTY THERETO, A COPY OF WHICH IS ON FILE WITH THE SECRETARY OF THE COMPANY. THE SHAREHOLDERS' AGREEMENT CONTAINS, AMONG OTHER THINGS, CERTAIN PROVISIONS RELATING TO THE VOTING AND TRANSFER OF THE SHARES SUBJECT TO THE AGREEMENT. NO TRANSFER, SALE, ASSIGNMENT, PLEDGE, HYPOTHECATION OR OTHER DISPOSITION OF THE SECURITIES REPRESENTED BY THIS CERTIFICATE MAY, DIRECTLY OR INDIRECTLY, BE MADE EXCEPT IN ACCORDANCE WITH THE PROVISIONS OF SUCH SHAREHOLDERS' AGREEMENT. THE HOLDER OF THIS CERTIFICATE, BY ACCEPTANCE OF THIS CERTIFICATE, AGREES TO BE BOUND BY ALL OF THE PROVISIONS OF SUCH SHAREHOLDERS' AGREEMENT. THE SHARES REPRESENTED BY THIS CERTIFICATE HAVE NOT BEEN REGISTERED UNDER THE SECURITIES ACT OF 1933 AND MAY NOT BE 5 TRANSFERRED OR OTHERWISE DISPOSED OF UNLESS THEY HAVE BEEN REGISTERED UNDER THAT ACT OR AN EXEMPTION FROM REGISTRATION IS AVAILABLE." This legend will be removed by the Company, with respect to any certificate representing Ordinary Shares, by the delivery of substitute certificates without such legend in the event of (i) a Transfer permitted or not prohibited by this Agreement and in which the Transferee is not required to, pursuant to this Article II, enter into an Assumption Agreement or a BACI Permitted Assign Agreement or (ii) the termination of this Agreement pursuant to the terms hereof, PROVIDED, HOWEVER, that the second paragraph of such legend will only be removed if at such time it is no longer required for purposes of applicable securities laws. (d) Prior to the earlier of (i) the Initial Public Offering and (ii) the date on which BA Capital Investors Sidecar Fund, L.P., together with any BACI Affiliate Transferees, shall no longer be entitled to designate a Director pursuant to Section 3.1, no Blackstone Entity may Transfer Ordinary Shares (other than in connection with a drag-along of all of BACI's Ordinary Shares pursuant to Section 2.5) if, as a result of such Transfer, the Blackstone Entities would own, in the aggregate, less than a majority of the outstanding Ordinary Shares, unless such transferee agrees in writing to be bound by such Blackstone Entity's obligations under Section 3.2 with respect to such transferred Ordinary Shares, to the same extent applicable to such Blackstone Entity. (e) Any Transfer by a Shareholder permitted under this Agreement shall be effective only upon receipt by the Company of information reasonably satisfactory to it, demonstrating that such Transfer is exempt from or not subject to the provisions of Section 5 of the Securities Act and any other applicable securities laws (for such purpose, an opinion of Kirkland & Ellis LLP, or other counsel reasonably acceptable to the Company, to that effect shall constitute such reasonably satisfactory information), provided that no such Transfer shall be permitted, except as permitted under the Registration Rights Agreement, if such Transfer would require the Company to register a class of equity securities under Section 12 of the Exchange Act under circumstances where the Company does not then have securities of any class registered under Section 12 of the Exchange Act and such Transfer would cause such registration to be required. 2.2 TRANSFERS TO BACI AFFILIATE TRANSFEREES. During or after the Initial Share Holding Period, BACI may Transfer Ordinary Shares, subject to compliance with the other provisions of this Agreement, to an Affiliate of Bank of America Corporation who duly executes and delivers to the Company and each Blackstone Entity an Assumption Agreement (a "BACI AFFILIATE TRANSFEREE"); PROVIDED, HOWEVER, that in the event a transaction or event is contemplated in which any BACI Affiliate Transferee to which Ordinary Shares are Transferred will cease to qualify as a BACI Affiliate Transferee, other than in connection with the BONA FIDE sale or other disposition by Bank of America Corporation, or any of its Affiliates, of a business unit that includes such BACI Affiliate Transferee, such BACI Affiliate Transferee to which Ordinary Shares are Transferred shall, and BACI shall cause such BACI Affiliate Transferee to: (i) promptly notify the Company of the pending occurrence of such transaction or event; and (ii) prior to the time such BACI Affiliate Transferee ceases to be a BACI Affiliate Transferee, Transfer back to BA Capital Investors Sidecar Fund, L.P. (or to another BACI Affiliate 6 Transferee) any Ordinary Shares it owns and such Transferee will execute and deliver an Assumption Agreement with respect thereto. 2.3 RIGHT OF FIRST REFUSAL. If at any time (i) during the Initial Share Holding Period and subject to the prior written consent of the Blackstone Representative as provided in Section 2.1, or (ii) before the six (6) month anniversary of the Initial Public Offering (or such shorter period as the underwriters for such Initial Public Offering shall require of either the Blackstone Entities or BACI), BACI proposes to Transfer, all or any portion of the Ordinary Shares held by it (other than (1) to a BACI Affiliate Transferee in accordance with Section 2.2, (2) as a Tagging Shareholder pursuant to Section 2.4, (3) as a Drag-Along Shareholder pursuant to Section 2.5 or (4) pursuant to the rights set forth in the Registration Rights Agreement) and BACI has received a bona fide arm's length offer for the Ordinary Shares subject to such Transfer, BACI shall deliver to the Blackstone Representative a written notice (the "OFFER NOTICE") of such proposed transaction, which shall identify the proposed Transferee and set forth the proposed terms of such Transfer, including the number of Ordinary Shares proposed to be Transferred and the purchase price therefor. The Offer Notice shall contain an irrevocable offer to sell to the Blackstone Entities the Ordinary Shares proposed to be Transferred at a price equal or equivalent (as determined in the manner set forth below) to the price contained in, and otherwise on the same terms and conditions of, the Offer Notice. The Blackstone Entities shall have fifteen (15) Business Days from the date the Offer Notice is received (the "OFFER PERIOD") to determine whether one or more of such Blackstone Entities, or one or more of their designees, shall exercise the right to purchase all (but not less than all) of the Ordinary Shares subject to the Offer Notice on the terms set forth in such Offer Notice, PROVIDED, HOWEVER, that if the proposed transaction includes any consideration other than cash, then, at the sole option of any such Blackstone Entity or designee, the relevant price shall be the equivalent cash price, determined (x) in the case of consideration consisting of securities listed or quoted on a national securities exchange or the Nasdaq National Market System, by the average daily closing sales price, as reported by Bloomberg L.P. (or if not reported by Bloomberg L.P., as reported by a reporting service of similar national reputation), of such securities on their principal trading market for the ten consecutive trading days preceding the date of receipt of the Offer Notice and (y) in the case of any other non-cash consideration, by the Board, acting reasonably and in good faith. If a Blackstone Entity does not respond to the Offer Notice within the Offer Period, then such Blackstone Entity will be deemed to have elected not to exercise the right of first refusal specified in the Offer Notice. If one or more of the Blackstone Entities and/or their respective designees shall have agreed to purchase Ordinary Shares pursuant to this Section 2.3, the applicable Blackstone Entities and/or their designees shall consummate such purchase by delivering, against receipt of certificates or other instruments representing the Ordinary Shares being purchased, appropriately endorsed by BACI, the purchase price for such Ordinary Shares. Such closing date will be the later of (i) fifteen (15) Business Days after the expiration of the Offer Period and (ii) five (5) Business Days after receipt of all governmental consents and approvals, and the expiration of all governmental waiting periods, required for such Transfer. BACI shall give participating Blackstone Entities and/or designees at least five (5) Business Days written notice of the closing date. 7 (b) If none of the Blackstone Entities exercises its right of first refusal under Section 2.3(a), then BACI shall be permitted to Transfer the Ordinary Shares subject to the Offer Notice, no later than sixty (60) days after the expiration of the Offer Period at a price not less than the purchase price per share set forth in the Offer Notice and on other terms not materially less favorable to BACI than those terms set forth in the Offer Notice. If BACI does not Transfer the Ordinary Shares in the time period provided for in this Section 2.3(b), any Transfer by BACI of any such shares after such period shall again be subject to this Section 2.3. 2.4 TAG-ALONG RIGHTS. Until the six (6) month anniversary of the Initial Public Offering (or such shorter period as the underwriters for such Initial Public Offering shall require of either the Blackstone Entities or BACI), if any Blackstone Entity (a "SELLING SHAREHOLDER") proposes to Transfer Ordinary Shares, which Transfer or series of related Transfers relates to more than 5% of the then-outstanding Ordinary Shares (other than (i) to an Affiliate that qualifies as a Permitted Assign or (ii) pursuant to the exercise of rights set forth in Section 2.5 or in the Registration Rights Agreement) (any such transaction, a "PROPOSED SALE"), then each of the other Shareholders that is not a Blackstone Entity will have the right to require the proposed Transferee (a "PROPOSED TRANSFEREE") to purchase from any such other Shareholder who exercises its rights pursuant to this Section 2.4 (a "TAGGING SHAREHOLDER") up to the number of Ordinary Shares equal to the product (rounded up to the nearest whole number) of (x) the quotient determined by DIVIDING (A) the aggregate number of Ordinary Shares owned by such Tagging Shareholder by (B) the aggregate number of Ordinary Shares owned by the Selling Shareholder(s) and all Tagging Shareholders and (y) the total number of Ordinary Shares proposed to be directly or indirectly Transferred to the Proposed Transferee, at the same price per Ordinary Share and upon the same terms and conditions (including, without limitation, time of payment, form of consideration and adjustments to purchase price) as the Selling Shareholder; PROVIDED that in order to be entitled to exercise its right to sell Ordinary Shares to the Proposed Transferee pursuant to this Section 2.4, each Tagging Shareholder shall agree to make to the Proposed Transferee the same representations, warranties, covenants, indemnities and agreements as the Selling Shareholder agrees to make in connection with the Proposed Sale and shall agree to the same conditions to the Proposed Sale as the Selling Shareholder agrees (except that, in the case of representations, warranties, conditions, covenants, indemnities and agreements pertaining specifically to the Selling Shareholder, each Tagging Shareholder shall make comparable representations, warranties, covenants, indemnities and agreements and shall agree to comparable conditions, in each case to the extent applicable and pertaining specifically to itself and only to itself); provided that all representations, warranties, covenants, indemnities and agreements (other than those referred to in the immediately preceding exception) shall be made by the Selling Shareholder and each Tagging Shareholder severally and not jointly and that any liability to the Selling Shareholder and the Tagging Shareholders thereunder shall be borne by each of them on a PRO RATA basis determined according to the number of Ordinary Shares sold by each of them. Each Tagging Shareholder will be responsible for its proportionate share of the costs of the Proposed Sale to the extent not paid or reimbursed by the Company, the Proposed Transferee or another Person (other than the Selling Shareholder). The Selling Shareholder shall be entitled to estimate each Tagging Shareholder's proportionate share of such costs and to withhold such amounts from payments to be made to such Tagging Shareholder at the time of closing of such Proposed Sale; PROVIDED that (i) such estimate shall not preclude the Selling Shareholder from recovering additional amounts from any Tagging Shareholder in respect of such Tagging Shareholder's proportionate share (based on the number of Ordinary Shares sold) 8 of such costs and (ii) the Selling Shareholder shall promptly reimburse each Tagging Shareholder to the extent actual amounts are ultimately less than the estimated amounts paid by such Tagging Shareholder or any such amounts are paid by the Company, the Proposed Transferee or another Person (other than the Selling Shareholder). (b) The Selling Shareholder will give notice to the other Shareholders of each Proposed Sale prior to the proposed closing date for such proposed Transfer, setting forth the number of Ordinary Shares proposed to be so Transferred, the name and address of the Proposed Transferee, the proposed amount and form of consideration (and if such consideration consists in part or in whole of property other than cash, the Selling Shareholder will provide such information, to the extent reasonably available to the Selling Shareholder, relating to such non-cash consideration as the Tagging Shareholders together may reasonably request in order to evaluate such non-cash consideration) and other terms and conditions of payment offered by the Proposed Transferee. The Selling Shareholder will deliver or cause to be delivered to each Tagging Stockholder copies of all transaction documents relating to the Proposed Sale promptly as the same become available. The tag-along rights provided by this Section 2.4 must be exercised by the Tagging Shareholders within fifteen (15) Business Days following receipt of the notice required to be delivered by the Selling Shareholder pursuant to this paragraph (b) by delivery of a written notice to the Selling Shareholder indicating such Tagging Shareholder's desire to exercise its rights and specifying the number of Ordinary Shares it desires to sell (the "TAG-ALONG NOTICE"). (c) If any Tagging Shareholder exercises its rights under this Section 2.4, the closing of the purchase of the Ordinary Shares with respect to which such rights have been exercised will take place concurrently with the closing of the sale of the Selling Shareholder's Ordinary Shares to the Proposed Transferee. The Seller Shareholder shall use reasonable efforts to obtain the agreement of the Proposed Transferee to the participation of all Tagging Shareholders in any applicable Transfer, and no Selling Shareholder shall consummate any transfer to which this Section 2.4 applies unless the Ordinary Shares entitled to be sold by the Tagging Shareholders pursuant to this Section 2.4 are purchased by the Proposed Transferee (or by the Selling Shareholder or its designee in lieu of such Proposed Transferee). (d) Notwithstanding anything contained in this Section 2.4, there shall be no liability on the part of the Selling Shareholder to any Tagging Shareholder if the Transfer of such Selling Shareholder's Ordinary Shares pursuant to this Section 2.4 is not consummated for any reason. Whether to effect a Proposed Sale of Ordinary Shares, or to terminate any such transaction prior to consummation, is in the sole and absolute discretion of such Selling Shareholder. (e) No Blackstone Entity shall avoid its obligations under this Section 2.4, or permit any of its Affiliates to take any action which, if taken by such Blackstone Entity, would be such an avoidance of its obligations, by transferring to a non-Affiliate equity interests in any Blackstone Intervening Entity in an amount and manner that, if such Transfer were of Ordinary Shares, would require such entity to comply with its obligations to Shareholders pursuant to this Section 2.4 without making appropriate accommodation to BACI, bearing in mind the provisions of this Section 2.4. 9 2.5 DRAG-ALONG RIGHTS. Until the six (6) month anniversary of the Initial Public Offering, so long as this Agreement remains in effect, if any Shareholder or Shareholders holding at least a majority of the aggregate outstanding Ordinary Shares (collectively, the "MAJORITY SHAREHOLDERS") receive an offer from a Person other than an Affiliate of such Shareholder or Shareholders (a "DRAG-ALONG BUYER") to purchase or otherwise acquire at least a majority of the aggregate outstanding Ordinary Shares and the Majority Shareholders propose to accept such offer, then each other Shareholder (collectively, the "DRAG-ALONG SHAREHOLDERS") shall, if requested by the Majority Shareholders in accordance with this Section 2.5, Transfer to such Drag Along Buyer, subject to Section 2.5(b), on the terms of the offer to be accepted by the Majority Shareholders, including, without limitation, time of payment, form of consideration and adjustments to purchase price, the number of Ordinary Shares equal to the number of Ordinary Shares owned by it multiplied by the percentage of the then-outstanding Ordinary Shares to which the Drag-Along Buyer's offer is applicable. For purposes of clarification, this Section 2.5 shall not apply to securities received by a Shareholder pursuant to a transaction contemplated by Section 2.4 or a prior exercise of this Section 2.5. (b) The Majority Shareholders will give notice (the "DRAG-ALONG NOTICE") to the Drag-Along Shareholders of any proposed Transfer giving rise to the rights of the Majority Shareholders set forth in Section 2.5(a) no later than fifteen (15) Business Days prior to the proposed closing date for such proposed Transfer. The Drag-Along Notice will set forth the number of Ordinary Shares proposed to be so Transferred, the name of the Drag-Along Buyer, the proposed amount and form of consideration (and if such consideration consists in part or in whole of property other than cash, the Majority Shareholders will provide such information, to the extent reasonably available to the Majority Shareholders, relating to such non-cash consideration as the Drag-Along Shareholders together may reasonably request in order to evaluate such non-cash consideration), the number of Ordinary Shares sought and the other terms and conditions of the offer. Each Drag-Along Shareholder shall agree to make the same representations, warranties, covenants, indemnities and agreements that the Majority Shareholders agree to make (except that, in the case of representations, warranties, conditions, covenants, indemnities and agreements pertaining specifically to any of the Majority Shareholders, each Drag-Along Shareholder shall make the comparable representations, warranties, covenants, indemnities and agreements and shall agree to comparable conditions, in each case to the extent applicable and pertaining specifically to itself and only to itself); PROVIDED that all representations, warranties, covenants, indemnities and agreements (other than those referred to in the immediately preceding exception) shall be made by each Majority Shareholder and each Drag-Along Shareholder severally and not jointly and that any liability of the Majority Shareholders and the Drag-Along Shareholders thereunder shall be borne by each of them on a PRO RATA basis determined according to the number of Ordinary Shares sold by each of them; and PROVIDED, FURTHER, that in no event shall any such indemnification obligation of any Drag-Along Shareholder in connection with such transaction exceed such Drag-Along Shareholder's proceeds of such transaction. In the event that any such Transfer is structured as a merger, consolidation or similar business combination, each Drag-Along Shareholder agrees to vote in favor of the transaction and to take all action to waive any dissenters, appraisal or other similar rights. Each Drag-Along Shareholder will be responsible for its proportionate share of the costs of such Transfer (except for any costs incurred solely for the benefit of individual shareholders, other than reasonable attorneys' fees of the Drag-Along Shareholders, which shall be included in the costs of such Transfer) to the extent not paid or reimbursed by the Company, the Drag-Along 10 Buyer or another Person (other than the Majority Shareholders). The Majority Shareholders shall be entitled to estimate each Drag-Along Shareholder's proportionate share of such costs and to withhold such amounts from payments to be made to such Drag-Along Shareholder at the time of closing of such Transfer; provided that (i) such estimate shall not preclude the Majority Shareholders from recovering additional amounts from any Drag-Along Shareholder in respect of such Drag-Along Shareholder's proportionate share of such costs and (ii) the Majority Shareholders shall reimburse each Drag-Along Shareholder to the extent actual amounts are ultimately less than the estimated amounts paid by such Drag-Along Shareholder or any such amounts are paid by the Company, the Drag-Along Buyer or another Person (other than the Majority Shareholders). 2.6 TERMINATION. Unless otherwise expressly provided for in this Article II, all sections in this Article II shall terminate with respect to any Shareholder on the date that is the six (6) month anniversary of the Initial Public Offering. ARTICLE III. CORPORATE GOVERNANCE MATTERS 3.1 BOARD OF DIRECTORS. The Blackstone Entities (or their respective designated Affiliates) shall be entitled, but not required, to designate all nominees for election to the Board (and shall designate at least two (2) such nominees), other than (i) any Directors entitled to be designated by the holders of the Preferred Shares pursuant to the Memorandum and Articles of Association (or comparable governing documents) of the Company and (ii) one Director which shall be designated by BA Capital Investors Sidecar Fund, L.P., together with any BACI Affiliate Transferees. Subject to applicable fiduciary duties, the Company and each Shareholder shall take all action necessary to effect such designations to the Board. Any Director not so designated by a Shareholder pursuant to this Section 3.1 shall be designated in accordance with the Memorandum and Articles of Association (or comparable governing documents) of the Company; PROVIDED that, to the extent permitted by law, in the event that BA Capital Investors Sidecar Fund, L.P., together with any BACI Affiliate Transferees, is entitled to designate a Director pursuant to this Section 3.1 and has not yet done so, such Director seat shall remain vacant until such designation is made, PROVIDED that BA Capital Investors Sidecar Fund, L.P. shall make such designation as promptly as possible. In addition, any Director designated by BA Capital Investors Sidecar Fund, L.P., together with any BACI Affiliate Transferees, shall be entitled to serve as a member of any committee of the Board that has been delegated decision-making authority by the Board, other than the audit committee and subject to applicable law and the rules of any applicable securities exchange or interdealer quotation system on which any securities of the Company are then listed. (b) Notwithstanding anything to the contrary in subsection (a) above, BA Capital Investors Sidecar Fund, L.P., together with any BACI Affiliate Transferees, shall not be entitled to designate any Director or director or other member of a comparable governing body pursuant to paragraph (a) of this Section 3.1 upon the later of (i) the date on which BA Capital Investors Sidecar Fund, L.P., together with any BACI Affiliate Transferees, ceases to hold Ordinary Shares representing at least 5% of the total outstanding Ordinary Shares and (ii) the consummation of the restructuring contemplated by Exhibit A hereto in substantially the manner reflected therein; PROVIDED that BA Capital Investors Sidecar Fund, L.P., together with any BACI Affiliate Transferees, shall thereafter be able to designate one non-voting observer (the 11 "OBSERVER") to the Board until such time as BA Capital Investors Sidecar Fund, L.P. and any BACI Affiliate Transferees no longer hold any Ordinary Shares. Any such Observer shall be entitled to receive all notices and materials distributed to Directors. (c) The Company shall take all necessary actions and each of the Shareholders hereby agrees to take such actions provided for under the terms of the Ordinary Shares held by them, in each case to appoint the designees referred to in Section 3.1(a) to the Board. If, following an election to the Board pursuant to this Section 3.1, any Director designated by a Shareholder shall resign or be removed or be unable to serve for any reason prior to the expiration of his or her term as a Director, the Shareholder that designated such Director may notify the Board in writing of a replacement designee and the Company shall take all necessary actions, and each of the Shareholders hereby agree to take such actions provided for under the terms of the Ordinary Shares held by them, in each case to appoint such designee to the Board. If a Shareholder who designated a Director pursuant to the terms of this Agreement requests that such designee be removed as a Director (with or without cause) by written notice thereof to the Company, then the Company shall take all necessary actions, and each of the Shareholders shall take all actions provided for under the terms of the Ordinary Shares held by them, in each case to effect such removal upon such request.

For purposes of clarification, for any entity that has a two-tier board structure, the comparable governing body shall be the supervisory board or comparable body (and not the management board or comparable body). (d) The Company will pay all reasonable out-of-pocket expenses incurred by the Directors (and, if applicable, any Observer designated pursuant to Section 3.1) in connection with their participation in meetings of the Board (and committees thereof), as well as such expenses of the members of the boards of directors or comparable governing bodies (and committees thereof) of the subsidiaries of the Company.
