and shall bear a legend on the reverse side thereof substantially in the following form:

THIS SECURITY IS SUBJECT TO CERTAIN RESTRICTIONS ON TRANSFER AND OTHER TERMS AND CONDITIONS SET FORTH IN (X) THE AMENDED AND RESTATED AGREEMENT OF EXEMPTED LIMITED PARTNERSHIP OF TDS INVESTOR (CAYMAN) L.P. (THE “PARTNERSHIP AGREEMENT”), (Y) THE SHAREHOLDERS’ AGREEMENT OF TDS INVESTOR (CAYMAN) GP LTD.

In addition to the legend required by Section 3.1(b) above, each Partner agrees that the Register of Partners and each Interest certificate heretofore or hereafter issued by the Partnership shall also bear such other legends as may be required by Law or the General Partner. Any such legend shall be removed by the General Partner upon the request (which shall include customary representations and opinions of counsel if reasonably requested by the General Partner) of a Partner when such legend is no longer applicable.

(d) Schedule A. The General Partner shall update Schedule A as required by the Partnership Act and ensure that it accurately reflects the information to be provided for therein. Any amendment or revision to Schedule A made in accordance with this Agreement shall not be deemed an amendment to this Agreement.

Section 3.2 Dispositions of Partnership Interests. No Limited Partner, nor any spouse of a Limited Partner, Personal Representative of a Limited Partner or legal representative or agent of a Limited Partner, may Dispose of all or any portion of such Limited Partner’s Interest, except in compliance with Article IV. Each of the Limited Partners agrees that the restrictions contained in this Agreement are fair and reasonable and in the best interest of the Partnership and the Partners.

Section 3.3. Admission of Additional Limited Partners. Any Person that acquires Interests pursuant to a Disposition of Interests to such Person by a Limited Partner in accordance with Article IV and the other provisions of this Agreement or pursuant to an issuance to such Person by the Partnership in accordance with this Agreement shall automatically be admitted as a Limited Partner without further action by the Partnership or the General Partner upon signing an Addendum Agreement in the form attached hereto as Exhibit C (an “Addendum Agreement”), which, in the case of OEP, was satisfied with the execution of the Joinder Agreement. No other Person that acquires an Interest shall be admitted to the Partnership as an additional limited partner of the Partnership in connection with a Disposition or an issuance by the Partnership, without the consent of the General Partner.

Section 3.4. Information.

(a) No Limited Partner shall be entitled to obtain any information relating to the Partnership except as expressly provided in this Agreement or in another written agreement between the Partnership and a Limited Partner giving such Limited Partner rights to receive information from the Partnership or to the extent required by the Partnership Act; and to the extent a Limited Partner is so entitled to such information, such Limited Partner shall be subject to the provisions of Section 3.4(b). The General Partner shall have access to all information regarding the Partnership subject to the provisions of Section 3.4(b).

(b) Subject to Section 10.3, each Partner agrees that all Confidential Information shall be kept confidential by such Partner and shall not be disclosed by such Partner in any manner whatsoever; provided, however, that (i) any of such Confidential Information may be disclosed by a Partner to its managers, officers, employees and authorized representatives (including attorneys, accountants, consultants, bankers and financial advisors of such Partner) and each Partner that is a limited partnership may disclose such Confidential Information to any former partners who retained an economic interest in such Partner, and to any current or prospective partner, limited partner, general partner or management company of such Partner (or any employee, attorney, accountant, consultant, banker or financial advisor or representative of any of the foregoing) (collectively, for purposes of this Section 3.4(b), “Representatives”), each of which Representatives shall be bound by the provisions of this Section 3.4(b), (ii) any disclosure of Confidential Information may be made by a Partner or its Representatives to the extent the Partnership consents in writing, and (iii) Confidential Information may be disclosed by any Partner or Representative to the extent that the Partner or its Representative has received advice from its counsel that it is legally compelled to do so, provided that, prior to making such disclosure, the Partner or Representative, as the case may be, uses commercially reasonable efforts to preserve the confidentiality of the Confidential Information, including consulting with the General Partner regarding such disclosure and, if reasonably requested by the General Partner, assisting the Partnership, at the Partnership’s expense, in seeking a protective order to

prevent the requested disclosure, and provided further that the Partner or Representative, as the case may be, discloses only that portion of the Confidential Information as is, based on the advice of its counsel, legally required.

Section 3.5. Cessation of Partnership Interest. A Partner shall automatically cease to be a Partner upon Disposition of all of such Partner’s Interests in accordance with this Agreement and the removal of such Partner’s name from the Register of Partners.

(b) Anything in this Agreement to the contrary notwithstanding, unless otherwise agreed to in writing by the General Partner, no Disposition of Interests otherwise permitted or required by this Agreement shall be effective unless and until any transferee who is not already a party to this Agreement (and such transferee’s spouse, if applicable) shall execute and deliver to the Partnership an Addendum Agreement in which such transferee (and such transferee’s spouse, if applicable) agrees to be bound by this Agreement and to observe and comply with this Agreement and with all obligations and restrictions imposed on the Partners hereby and thereby. Any Person who is not already a party to this Agreement and acquires Interests in accordance with the provisions of this Agreement shall be required to become a party to this Agreement by executing (together with such Person’s spouse, if applicable) an Addendum Agreement.

(f) Each of the Class A-1 Limited Partners agrees that any Disposition of Class A-1 Interests pursuant to the terms of this Agreement shall be accompanied by a proportionate Disposition of such Class A-1 Limited Partner’s shares in the General Partner pursuant to Section 4.3 of the Shareholders’ Agreement. Any such Disposition of Class A-1 Interests which is not accompanied by a Disposition of a proportionate amount of such Class A-1 Limited Partner’s shares in the General Partner shall be null and void.

(g) Any issuance of Class A-1 Interests to a Class A-1 Limited Partner or to any other Person pursuant to the terms of this Agreement shall be accompanied by an issuance to such Person of a proportionate amount of shares in the General Partner pursuant to Section 5.2 of the Shareholders’ Agreement, and such Class A-1 Limited Partner shall be required to pay the subscription amount to the General Partner required in connection therewith; provided, that this requirement shall not apply to OEP, which shall coordinate with the General Partner to subscribe for shares of the General Partner and enter into the Shareholders Agreement as soon as practicable after the date hereof. Except with respect to OEP’s investment in Class A-1 Interests in connection with the execution of the Joinder Agreement, any issuance of Class A-1 Interests which is not accompanied by an issuance of a proportionate amount of shares in the General Partner to such Person shall be null and void.

Section 4.2. Class A-1 Permitted Dispositions.

(a) Subject to the provisions of Section 4.1, Class A-1 Interests may only be Disposed (i) to a Person who is a Permitted Transferee with respect to the transferring Partner (and each such Permitted Transferee may in turn make any such Disposition to another Person who is a Permitted Transferee with respect to the initial transferring Partner upon the same terms and conditions), (ii) following the third anniversary of the date of this Agreement, (iii) prior to the third anniversary of the date of this Agreement with the consent of the General Partner, (iv) by one Sponsor Group to another Sponsor Group, or (iv) pursuant to a Limited Partner’s rights as a Class A-1 Tag Offeree under Section 4.3 or in connection with a drag-along sale pursuant to and in accordance with Section 4.4.

(b) Any transfer made pursuant to clauses (i) and (iv) of Section 4.2(a) above shall not be subject to the terms of Section 4.3 below.

(c) The provisions of this Section 4.2 shall terminate upon a Qualified Public Offering.

Section 4.3. Class A-1 Tag-Along Rights.

(a) No Blackstone Partner shall sell or otherwise effect the Disposition of any Class A-1 Interests (in one or a series of transactions) to a third party (excluding for such purpose Dispositions in connection with a Qualified Public Offering) unless the terms and conditions of such Disposition include an offer, on the same terms as the offer to the selling Partner (the “Class A-1 Selling Partner”), to each of the other Class A-1 Limited Partners (collectively, the “Class A-1 Tag Offerees”), to include at the option of each Class A-1 Tag Offeree, in the sale or other Disposition to the third party, a number of Class A-1 Interests owned by each Class A-1 Tag Offeree determined in accordance with this Section 4.3.

(b) The Class A-1 Selling Partner shall cause the third party offer to be reduced to writing (which writing shall include an offer to purchase or otherwise acquire Class A-1 Interests from the Class A-1 Tag Offerees as required by this Section 4.3 and a time and place designated for the closing of such purchase, which time shall not be less than 10 days after delivery of such notice) and shall send written notice of such third party offer (the “Class A-1 Inclusion Notice”) to each of the Class A-1 Tag Offerees and the General Partner in the manner specified herein.

(c) Each Class A-1 Tag Offeree shall have the right (an “Class A-1 Inclusion Right”), exercisable by delivery of notice to the Class A-1 Selling Partner at any time within ten Business Days after receipt of the Class A-1 Inclusion Notice, to sell pursuant to such third party offer, and upon the terms and conditions set forth in the Class A-1 Inclusion Notice, that number of Class A-1 Interests requested to be included by such Class A-1 Tag Offeree; provided, however, that if the proposed third party transferee is unwilling to purchase all of the Class A-1 Interests requested to be sold by all exercising Class A-1 Tag Offerees, then each Class A-1 Tag Offeree shall have the right to sell pursuant to such third party offer, and upon the terms and conditions set forth in the Class A-1 Inclusion Notice, a number of such Class A-1 Tag Offeree’s Class A-1 Interests equal to the product of (x) such Class A-1 Tag Offeree’s Class A-1 Interests multiplied by (y) the percentage of Class A-1 Interests that the Class A-1 Selling Partner is proposing to sell relative to the total number of Class A-1 Interests held by such Class A-1 Selling Partner and its Affiliates. If any Class A-1 Tag Offeree has exercised its Class A-1 Inclusion Rights and the proposed third party transferee is unwilling to purchase all of the Class A-1 Interests proposed to be transferred by all exercising Class A-1 Tag Offerees (determined in accordance with the first sentence of this Section 4.3(c)), then the Class A-1 Selling Partner and each exercising Class A-1 Tag Offeree shall reduce, on a pro rata basis based on their respective Percentage Interests of the Class A-1 Interests, the amount of such Class A-1 Interests that each otherwise would have sold so as to permit the Class A-1 Selling Partner and each exercising Class A-1 Tag Offeree to sell the amount of Class A-1 Interests (determined in accordance with such reduced Percentage Interests), that the proposed third party transferee is willing to purchase.

(d) The Class A-1 Tag Offerees and the Class A-1 Selling Partner shall sell to the proposed third party transferee the Class A-1 Interests proposed to be transferred by them in accordance with this Section 4.3, at the time and place provided for the closing in the Class A-1 Inclusion Notice, or at such other time and place as the Class A-1 Tag Offerees, the Class A-1 Selling Partner, and the proposed third party transferee shall agree.

(e) The provisions of this Section 4.3 shall terminate upon a Qualified Public Offering.

Section 4.4. Class A-1 Drag-Along Rights.

(a) If a Class A-1 Limited Partner (the “Class A-1 Drag Partner”) receives an offer from a Person or group of Persons that is not a Permitted Transferee or Affiliate of the Blackstone Group or the Partnership to purchase a number of Interests (the “Class A-1 Drag Interests”) that is not less than a majority of the outstanding Class A-1 Interests (calculated as a single class) and such offer is accepted by Partners holding a majority of the outstanding Class A-1 Interests, then the Class A-1 Drag Partner may require each Class A-1 Limited Partner to sell to the applicable buyer(s) a number of Class A-1 Interests that is equal to the product of (i) the number of Class A-1 Interests owned by such Limited Partner and (ii) a fraction (expressed as a percentage), the numerator of which is the number of Class A-1 Drag Interests and the denominator of which is the total number of outstanding Class A-1 Interests (such percentage, the “Class A-1 Relevant Percentage”, and any such transaction, an “Approved Class A-1 Sale”). In any such Approved Class A-1 Sale, all selling Class A-1 Limited Partners must receive the same benefits (including the same consideration per Interest) and bear the same burdens as the Class A-1 Drag Partner, subject to Section 4.4(c). To the extent any such transaction shall be structured as (I) a merger, conversion, Interest exchange, consolidation, transfer by way of continuation of the Partnership, or a sale of all or substantially all of the assets of the Partnership, each Class A-1 Limited Partner entitled to vote thereon shall vote in favor of such Approved Class A-1 Sale and shall waive any appraisal rights or similar rights in connection with such merger, conversion, exchange, consolidation or transfer by way of continuation or asset sale, or (II) a sale of Class A-1 Interests, the Class A-1 Limited Partners shall agree to sell all of their Interests which are the subject of the Approved Class A-1 Sale, on the terms and conditions of such Approved Class A-1 Sale.

(b) In order to exercise the rights contemplated by this Section 4.4, the Class A-1 Drag Partner must give written notice to each other Class A-1 Limited Partner as soon as practicable, but in no event later than the earlier of (i) fifteen Business Days following the execution of the relevant agreement and (ii) twenty Business Days prior to the anticipated closing date of the Approved Class A-1 Sale. Such notice must set forth the name of the proposed buyer(s), the proposed amount and form of consideration and the other terms and conditions of the offer, including a copy of the relevant agreement.

(c) Notwithstanding anything herein to the contrary, no Class A-1 Limited Partner shall be required to take any actions under this Section 4.4 in connection with an Approved Class A-1 Sale, unless (i) such Class A-1 Limited Partner is not responsible or otherwise liable for more than the lesser of (x) its pro rata share (based upon the actual amount of consideration received) of any holdback, escrow or indemnification obligation (other than indemnities in respect to representations and warranties regarding such Class A-1 Limited Partner’s title to its Class A-1 Interests, due execution and due authorization), and (y) an amount equal to the actual consideration received by such Class A-1 Limited Partner in such Approved Class A-1 Sale; and (ii) if any Class A-1 Limited Partner is given an option as to the form of consideration to be received, all other such Class A-1 Limited Partners shall be given the same option.

(d) The provisions of this Section 4.4 shall terminate upon a Qualified Public Offering.

Section 4.5. Conversion to IPO Corporation.

(a) In connection with any proposed Qualified Public Offering approved in accordance with this Agreement, the General Partner, at its election, may amend this Agreement to provide for a share capital, convert in accordance with Cayman Islands Law to a company limited by shares or other capital structure as the General Partner may determine, form a subsidiary holding company and distribute its shares to the Partners, move the Partnership or any successor to another jurisdiction to facilitate any of the foregoing, or take such other steps as it deems necessary to create a suitable vehicle for an offering, in each such case in accordance with the Partnership Act and applicable Law (the resulting entity, the “IPO Corporation”), and in each case for the express purpose of an initial offering of the securities of such IPO Corporation for sale to the public in a registered public offering pursuant to the Securities Act that is a Qualified Public Offering (an “IPO Conversion”). In connection therewith each Class A-1 Limited Partner agrees to cooperate with the other Class A-1 Limited Partners in good faith in order to effectuate the IPO Conversion and ensure that each Class A-1 Limited Partner receives shares (or other equity securities) and other rights in connection with such IPO Conversion substantially equivalent to its economic interest, governance, priority and other rights and privileges as such Class A-1 Limited Partner had prior to such IPO Conversion and are consistent with the rights and preferences attendant to such Class A-1 Interests as set forth in this Agreement as in effect immediately prior to such IPO Conversion and to ensure that such rights and privileges are reflected in the organizational and other documents of the IPO Corporation. In the event the General Partner determines that the Partnership should engage in an IPO Conversion, the Class A-1 Limited Partners will use commercially reasonable efforts to cooperate with each other so the IPO Conversion is undertaken in a tax-efficient manner for all Class A-1 Limited Partners.

(b) In connection with any proposed IPO Conversion, at the option of the General Partner all or any portion of the Management Interests may (i) be converted into or redeemed for shares (or other equity securities and/or options at fair market value) and other rights with substantially equivalent economic, governance, priority and other rights and privileges as in effect immediately prior to such IPO Conversion (disregarding the tax treatment of such conversion or redemption) or (ii) remain outstanding; provided that the General Partner shall only take the action described in clause (i) if the General Partner determines in good faith that the failure to take such action would be materially adverse to the best interests of all Partners of the Partnership taken as a whole (it being understood that for purposes of such determination the availability of tax deductions arising from redeeming or converting Management Interests, in whole or in part, for options shall not be taken into consideration by the General Partner). If the General Partner shall elect to take the action referred to in clause (i), the Partnership shall use commercially reasonable efforts to cooperate with Management Limited Partners so the IPO Conversion, to the extent possible, is undertaken in a tax-efficient manner for all Management Limited Partners. If any such conversion or redemption is effected in compliance with this Section 4.5, each Management Limited Partner agrees to consent to and raise no objection to such conversion or redemption and shall execute and deliver all agreements, instruments and

documents as may be reasonably required in order to consummate such conversion or redemption.

(c) Notwithstanding Section 4.5(b), following an IPO Conversion, contemporaneously with the later of (i) the occurrence of the Lapse Date with respect to a Management Limited Partner and (ii) the date on which all of a Management Limited Partner’s Management Interests become Vested Interests, such Management Limited Partner shall have the right, on 15 Business Days prior written notice to the Partnership, to have all of its Management Interests redeemed by the Partnership for corresponding shares or other securities of the IPO Corporation; provided that upon exercise of such right the applicable Management Limited Partner shall become a party to a stockholders agreement with IPO Corporation providing for substantially similar obligations as those provided in this Agreement.

(d) The General Partner shall give each Class A-1 Limited Partner at least 30 days’ prior written notice of any IPO Conversion as to which the Partnership intends to exercise its rights under Section 4.5. If the General Partner elects to exercise its rights under Section 4.5, the Partners shall take such actions as may be reasonably required and otherwise cooperate in good faith with the General Partner, including taking all actions required by the General Partner, in connection with consummating the IPO Conversion (including, without limitation, the voting of any Interests (including any voting as Partners as may be necessary to effect a transfer by continuation or to authorize a share capital, whether by liquidation of the Partnership and creation of a new entity, amendment to this Agreement or otherwise), to approve such IPO Conversion and to take any other actions required in order to effectuate an IPO Conversion).

Section 4.6. Management Interests Permitted Dispositions. Subject to the provisions of Section 4.1, Management Interests may only be Disposed (a) to a Person who is a Permitted Transferee with respect to the transferring Management Limited Partner (and each such Permitted Transferee may in turn make any such Disposition to another Person who is a Permitted Transferee with respect to the initial transferring Management Limited Partner upon the same terms and conditions), (b) subject to compliance with Section 4.9, following the Lapse Date applicable to such Management Limited Partner, (c) prior to the Lapse Date applicable to such Management Limited Partner with the consent of the General Partner (which consent shall be granted or withheld in the sole discretion of the General Partner without regard to the best interests of the Partnership or any Limited Partner) or (d) pursuant to a Management Limited Partner’s rights as a Management Tag Offeree under Section 4.7 or in connection with a drag-along sale pursuant to and in accordance with Section 4.8.

Section 4.7. Management Interest Tag-Along Rights.

(a) The Blackstone Partners shall not sell or otherwise effect the Disposition of more than 25% of the Class A-1 Interests held collectively by the Blackstone Partners on the date of this Agreement (in one or a series of transactions, regardless of whether such transactions are related) to a third party (excluding for such purpose Dispositions in connection with a Qualified Public Offering) unless the terms and conditions of such Disposition include an offer, on the same terms (except that (x) the price per Interest shall be adjusted to reflect the relative values of the applicable Interests in light of the distribution priorities set forth in Article VII and (y) any consideration otherwise payable in kind may, at the election of the buyer, be paid in cash

of equivalent value) as the offer to the selling Partner (the “25% Selling Partner”), to each of the Management Limited Partners (collectively, the “Management Tag Offerees”), to include at the option of each Management Tag Offeree, in the sale or other Disposition to the third party, a number of each class of Management Interests owned by each Management Tag Offeree determined in accordance with this Section 4.7.

(b) The 25% Selling Partner shall cause the third party offer to be reduced to writing (which writing shall include an offer to purchase or otherwise acquire Management Interests from the Management Tag Offerees as required by this Section 4.7 and a time and place designated for the closing of such purchase, which time shall not be less than 10 days after delivery of such notice) and shall send written notice of such third party offer (the “Management Inclusion Notice”) to each of the Management Tag Offerees in the manner specified herein.

(c) Each Management Tag Offeree shall have the right (a “Management Inclusion Right”), exercisable by delivery of notice to the 25% Selling Partner at any time within ten Business Days after receipt of the Management Inclusion Notice, to sell pursuant to such third party offer, and upon the terms and conditions set forth in the Management Inclusion Notice, that number of each class of Management Interests equal to the product of (x) such Management Tag Offeree’s Interests of such class multiplied by (y) the percentage of Class A-1 Interests that the 25% Selling Partner is proposing to sell (or has previously sold in a transaction subject to Section 4.3 but not Section 4.7) relative to the total number of Class A-1 Interests held by such 25% Selling Partner and its Affiliates on the date of this Agreement (provided that, with respect to any subsequent Management Inclusion Right, the percentage shall be based on the percentage of Class A-1 Interests that the 25% Selling Partner is proposing to sell (or has sold in any transaction subject to Section 4.3 but not 4.7 since the previous exercise of a Management Inclusion Right) relative to the total number of Class A-1 Interests held by such 25% Selling Partner and its Affiliates immediately following the exercise of the most recent Management Inclusion Right).

(d) The Management Tag Offerees and the 25% Selling Partner shall sell to the proposed third party transferee the Management Interests proposed to be transferred by them in accordance with this Section 4.7, at the time and place provided for the closing in the Management Inclusion Notice, or at such other time and place as the Management Tag Offerees, the 25% Selling Partner, and the proposed third party transferee shall agree.

(e) Notwithstanding the foregoing, the tag-along provisions of this Section 4.7 shall only apply to Management Interests which are Vested Interests (or which would become Vested Interests as a result of the transactions contemplated by this Section 4.7), assuming for purposes of this Section 4.7 that the distributions pursuant to Section 7.1 are deemed to be effected pro forma for the proposed tag-along transaction, and Management Interests which are not Vested Interests shall not be regarded as Interests for purposes of this Section 4.7.

Section 4.8. Management Drag-Along Rights.

(a) If a Blackstone Partner (the “Blackstone Drag Partner”) receives an offer from a Person or group of Persons that is not a Permitted Transferee or Affiliate of the Blackstone Group or the Partnership to purchase more than 25% of the Class A-1 Interests held

collectively by them on the date of this Agreement (the “Blackstone Drag Interests”), then the Blackstone Drag Partner may require each Management Limited Partner to sell to the applicable buyer(s) a number of each class of Interests that is equal to up to the product of (i) the number of such class of Interests owned by such Management Limited Partner and (ii) a fraction (expressed as a percentage), the numerator of which is the number of Blackstone Drag Interests and the denominator of which is the total number of outstanding Class A-1 Interests held by the Blackstone Group (such percentage, the “Management Relevant Percentage”, and any such transaction, a “Approved Management Interest Sale”). In any such Approved Management Interest Sale, all selling Management Limited Partners must receive the same relative benefits (except that (x) the price per Interest shall be adjusted to reflect the relative values of the applicable Interests in light of the distribution priorities set forth in Article VII and (y) any consideration otherwise payable in kind may, at the election of the buyer, be paid in cash of equivalent value) and bear the same relative burdens as the Blackstone Drag Partner, subject to Section 4.8(c). To the extent any such transaction shall be structured as (I) a merger, conversion, Interest exchange, consolidation, transfer by way of continuation of the Partnership, or a sale of all or substantially all of the assets of the Partnership, each Management Limited Partner entitled to vote thereon shall vote in favor of such Approved Management Interest Sale and shall waive any appraisal rights or similar rights in connection with such merger, conversion, exchange, consolidation or transfer by way of continuation or asset sale, or (II) a sale of Interests, the Management Limited Partners shall agree to sell all of their Management Interests which are the subject of the Approved Management Interest Sale, on the terms and conditions of such Approved Management Interest Sale.

(b) In order to exercise the rights contemplated by this Section 4.8, the Blackstone Drag Partner must give written notice to each Management Limited Partner as soon as practicable, but in no event later than the earlier of (i) twenty Business Days following the execution of the relevant agreement and (ii) ten Business Days prior to the anticipated closing date of the Approved Management Interest Sale. Such notice must set forth the name of the proposed buyer(s), the proposed amount and form of consideration and the other terms and conditions of the offer, including a copy of the relevant agreement.

(c) Notwithstanding anything herein to the contrary, no Management Limited Partner shall be required to take any actions under this Section 4.8 in connection with a Approved Management Interest Sale, unless such Management Limited Partner is not responsible or otherwise liable for more than the lesser of (x) its pro rata share (based upon the actual amount of consideration received) of any holdback, escrow or indemnification obligation (other than indemnities in respect to representations and warranties regarding such Management Limited Partner’s title to its Management Interests, due execution and due authorization), and (y) an amount equal to the actual consideration received by such Management Limited Partner in such Approved Management Interest Sale.

(d) Notwithstanding the foregoing, the drag-along provisions of this Section 4.8 shall apply to all Management Interests, assuming for purposes of this Section 4.8 that the distributions pursuant to Section 7.1 are deemed to be effected pro forma for the proposed Approved Management Interest Sale.

Section 4.9. Right of First Refusal.

(a) After the Lapse Date applicable to a Management Limited Partner and until the occurrence of a Qualified Public Offering (the “ROFR Period”), the Partnership shall have a right of first refusal with respect to any proposed Disposition of Management Interests by a Management Limited Partner (each a “Transferring Management Limited Partner”), and any Transferring Management Limited Partner must first comply with the provisions of this Section 4.9. The Partnership may assign this right to one or more Blackstone Partners, TCV Partners or OEP Partners (in which case all references in this Section 4.9 shall be deemed to be references to the applicable Blackstone Partner, TCV Partner or OEP Partner); provided, that any such assignment shall be pro rata among each Blackstone Partner, TCV Partner and OEP Partner wishing to exercise such right.

(b) At any time a Transferring Management Limited Partner proposes to make a bona fide Disposition of Management Interests during the ROFR Period (other than (i) a Disposition pursuant to clause (a) or (d) of Section 4.6 or (ii) pursuant to the Registration Rights Agreement), and such Transferring Management Limited Partner has received a bona fide arm’s length offer (the “Offer”) to purchase all or any portion of its Management Interests (the “Offered Interests”) from any Person (the “Offeror”) which the Transferring Management Limited Partner wishes to accept, such Transferring Management Limited Partner shall cause the Offer to be reduced to writing and shall notify the Partnership in writing of its wish to accept the Offer (the “Offering Notice”).

(c) The Offering Notice shall contain an irrevocable offer to sell the Offered Interests to the Partnership at a price equal or equivalent (as determined in the manner set forth in Section 4.9(c)(i) below) to the price contained in, and otherwise on the same terms and conditions of, the Offer and shall be accompanied by a copy of the Offer (which shall identify the Offeror).

(i) For a period of 20 Business Days after the date upon which the Partnership shall have received the Offering Notice (the “Partnership Option Period”), the Partnership shall have the right to elect to purchase all (but not less than all) of the Offered Interests either (A) at the same price and on the same terms and conditions as the Offer or (B) if the Offer includes any consideration other than cash, then at the sole option of the Partnership, at the equivalent cash price, determined in good faith by the General Partner. If the Partnership does not elect to purchase all of the Offered Interests pursuant to this Section 4.9(c), then the Transferring Management Limited Partner may sell all of the Offered Interests to the Offeror in accordance with Section 4.9(e).

(ii) The right of the Partnership to purchase the Offered Interests under Section 4.9(c) shall be exercisable by delivering written notice of the exercise thereof, prior to the expiration of the Partnership Option Period, to the Transferring Management Limited Partner. The failure of the Partnership to deliver such a notice to the Transferring Management Limited Partner within the Partnership Option Period to the Transferring Management Limited Partner shall be deemed to be a waiver of the Partnership’s rights under Section 4.9(c).

(d) The closing of the purchase of Offered Interests subscribed for by the Partnership under Section 4.9(c) shall be held at the executive office of the Partnership at 11:00

a.m., local time, no later than 25 Business Days after the Partnership’s election to purchase the Offered Interests pursuant to Section 4.9(c) is delivered to the Transferring Management Limited Partner or at such other time and place as the parties to the transaction may agree; provided that if such sale is subject to any prior regulatory approval, then such 30-day period shall be extended until the expiration of 15 Business Days after all such approvals shall have been received, but in no event shall such period be extended for more than an additional 60 days without the consent of the Transferring Management Limited Partner. At such closing, the Transferring Management Limited Partner shall deliver certificates representing the Offered Interests (or other applicable transfer instruments), duly endorsed for transfer and accompanied by all requisite transfer taxes, if any, and such Offered Interests shall be free and clear of any liens, and the Transferring Management Limited Partner shall so represent and warrant, and shall further represent and warrant that it is the sole beneficial and legal owner of such Offered Interests with the full right, power and authority to convey the Offered Interests to the Partnership. The Partnership shall deliver at the closing payment in full in immediately available funds for the Offered Interests purchased by it. At such closing, all of the parties to the transaction shall execute such additional documents as are otherwise necessary or appropriate.

(e) If the Partnership does not elect to purchase all of the Offered Interests under Section 4.9(c), or if the Partnership does so elect but the regulatory approvals necessary to consummate such purchase are not obtained within the time periods referred to in Section 4.9(d), then the Transferring Management Limited Partner may sell all (but not less than all) of the Offered Interests to the Offeror on terms and conditions no less favorable to the Transferring Management Limited Partner than those set forth in the Offering Notice; provided, however, that such sale is bona fide and made pursuant to a contract entered into not later than 45 days after the earlier to occur of (i) the waiver by the Partnership of its option to purchase the Offered Interests and (ii) the expiration of the Partnership Option Period (the “Contract Date”); and provided, further, that such sale shall not be consummated unless and until (A) such Offeror shall represent in writing to the Partnership that it is aware of the rights and obligations of the Partnership contained in this Agreement and (B) prior to the purchase by such Offeror of such Offered Interests, such Offeror shall become a party to this Agreement and shall agree to be bound by the terms and conditions hereof to the same extent as the Transferring Management Limited Partner. If such sale is not consummated within 60 days after the Contract Date for any reason, then the restrictions provided for herein shall again become effective, and no Disposition of such Offered Interests may be made thereafter by the Transferring Management Limited Partner without again complying with this Section 4.9; provided that if such sale is subject to any prior regulatory approval, then such 30-day period shall be extended until the expiration of 10 Business Day after all such approvals shall have been received, but in no event shall such period be extended for more than an additional 120 days without the consent of the Partnership.

Section 4.10. Specific Performance. Each of the parties to this Agreement acknowledges that it shall be impossible to measure in money the damage to the Partnership or the Partners(s), if any of them or any transferee or any legal representative of any party hereto fails to comply with any of the restrictions or obligations imposed by this Article IV, that every such restriction and obligation is material, and that in the event of any such failure, neither the Partnership nor the Partner(s) shall have an adequate remedy at law or in damages. Therefore, each party hereto consents to the issuance of an injunction or the enforcement of other equitable remedies against it at the suit of an aggrieved party without the posting of any bond or other

equity security, to compel specific performance of all of the terms of this Article IV and to prevent any Disposition of Interests in contravention of any terms of this Article IV, and waives any defenses thereto, including, without limitation, the defenses of: (i) failure of consideration; (ii) breach of any other provision of this Agreement; and (iii) availability of relief in damages. The provisions of this Section 4.10 shall terminate with respect to any Sponsor Group upon a Qualified Public Offering.

(vii) Seventh, so long as each Class A Limited Partner has received an amount equal to 3.0 times its capital contributions pursuant to Section 5.1 (adjusted, with respect to Class A Interests, in the manner described in the parenthetical in Priority Second), pro rata to each holder of Class D Interests based on its Percentage Interest of Class D Interests until such Class D Limited Partner has received an amount equal the sum of (A) its Capital Contributions and (B) the same amount received by a Class C Limited Partner under Clause (B) of Priority Fifth and Priority Sixth, proportionally based on their respective Percentage Interests of all Class C Interests and Class D Interests; and

Section 7.2. Tax Distributions. If the General Partner reasonably determines that the taxable income of the Partnership for a taxable year will give rise to taxable income for the Partners (after giving effect to any net cumulative taxable losses from prior taxable years (“Net Taxable Income”)), the General Partner shall cause the Partnership to distribute cash available for distribution (if any) for purposes of allowing the Partners to fund their respective income tax liabilities (the “Tax Distributions”). The Tax Distributions with respect to any taxable year shall be computed based upon the General Partner’s estimate of the Net Taxable Income, multiplied by the Applicable Tax Percentage (the “Tax Amount”) and shall only be paid to the extent previous distributions pursuant to Section 7.1 during such taxable year are insufficient to cover the Tax Amount for such taxable year. Tax Distributions shall be distributed to the Partners on a

Each Management Limited Partner shall submit such 83(b) Election to the IRS within 30 calendar days after acquiring the Interests and shall promptly send a copy to the Partnership.

ARTICLE VIII

ALLOCATIONS

Section 8.1. Allocations of Profits and Losses. Except as otherwise provided in this Agreement, Profits and Losses and to the extent necessary, individual items of income, gain or loss or deduction of the Partnership shall be allocated in a manner such that the Capital Account of each Partner after giving effect to the Special Allocations set forth in Section 8.2 is, as nearly as possible, equal (proportionately) to (i) the distributions that would be made pursuant to Section 7.1 if the Partnership were dissolved, its affairs wound up and its assets sold for cash equal to their Book Value, all Partnership liabilities were satisfied (limited with respect to each non-recourse liability to the Book Value of the assets securing such liability) and the net assets of the Partnership were distributed in accordance with Section 7.1 to the Partners immediately after making such allocation, minus (ii) such Partner’s share of Partner Minimum Gain and Partner Nonrecourse Debt Minimum Gain, computed immediately prior to the hypothetical sale of assets.

Section 8.2. Special Allocations. Notwithstanding any other provision in this Article VIII:

(a) Minimum Gain Chargeback. If there is a net decrease in Partner Minimum Gain or Partner Nonrecourse Debt Minimum Gain (determined in accordance with the principles of Treasury Regulations Sections 1.704-2(d) and 1.704-2(i)) during any Partnership taxable year, the Partners shall be specially allocated items of Partnership income and gain for such year (and, if necessary, subsequent years) in an amount equal to their respective shares of such net decrease during such year, determined pursuant to Treasury Regulations Sections 1.704-2(g) and 1.704-2(i)(5). The items to be so allocated shall be determined in accordance with Treasury Regulations Section 1.704-2(f). This Section 8.2(a) is intended to comply with the minimum gain chargeback requirements in such Treasury Regulations Sections and shall be interpreted consistently therewith; including that no chargeback shall be required to the extent of the exceptions provided in Treasury Regulations Sections 1.704-2(f) and 1.704-2(i)(4).

(b) Qualified Income Offset. If any Partner unexpectedly receives any adjustments, allocations, or distributions described in Treasury Regulations Section 1.704-1(b)(2)(ii)(d)(4), (5) or (6), items of Partnership income and gain shall be specially allocated to such Partner in an amount and manner sufficient to eliminate the deficit balance in such Partner’s

Adjusted Capital Account Balance created by such adjustments, allocations or distributions as promptly as possible; provided, that an allocation pursuant to this Section 8.2(b) shall be made only to the extent that a Partner would have a deficit Adjusted Capital Account Balance in excess of such sum after all other allocations provided for in this Article VIII have been tentatively made as if this Section 8.2(b) were not in this Agreement. This Section 8.2(b) is intended to comply with the “qualified income offset” requirement of the Code and shall be interpreted consistently therewith.

(c) Gross Income Allocation. If any Partner has a deficit Capital Account at the end of any taxable year which is in excess of the sum of (i) the amount such Partner is obligated to restore, if any, pursuant to any provision of this Agreement, and (ii) the amount such Partner is deemed to be obligated to restore pursuant to the penultimate sentences of Treasury Regulations Section 1.704-2(g)(1) and 1.704-2(i)(5), each such Partner shall be specially allocated items of Partnership income and gain in the amount of such excess as quickly as possible; provided, that an allocation pursuant to this Section 8.2(c) shall be made only if and to the extent that a Partner would have a deficit Capital Account in excess of such sum after all other allocations provided for in this Article VIII have been tentatively made as if Section 8.2(b) and this Section 8.2(c) were not in this Agreement.

(d) Nonrecourse Deductions. Nonrecourse Deductions shall be allocated to the Partners ratably in accordance with such Partners’ Interests.

(e) Partner Nonrecourse Deductions. Partner Nonrecourse Deductions for any taxable period shall be allocated to the Partner who bears the economic risk of loss with respect to the liability to which such Partner Nonrecourse Deductions are attributable in accordance with Treasury Regulations Section 1.704-2(j).

(f) Creditable Foreign Taxes. Creditable Foreign Taxes for any taxable period attributable to the Partnership, or an entity owned directly or indirectly by the Partnership, shall be allocated to the Partners in proportion to the partners’ distributive shares of income (including income allocated pursuant to Section 704(c) of the Code) to which the Creditable Foreign Tax relates (under principles of Treasury Regulations Section 1.904-6). The provisions of this Section 8.2(f) are intended to comply with the provisions of Temporary Treasury Regulations Section 1.704-1T(b)(4)(xi), and shall be interpreted consistently therewith.

(g) Ameliorative Allocations. Any special allocations of income or gain pursuant to Sections 8.2(b) or 8.2(c) hereof shall be taken into account in computing subsequent allocations pursuant to Section 8.1 and this Section 8.2(g), so that the net amount of any items so allocated and all other items allocated to each Partner shall, to the extent possible, be equal to the net amount that would have been allocated to each Partner if such allocations pursuant to Sections 8.2(b) or 8.2(c) had not occurred.

Section 8.3. Income Tax Allocations. For income tax purposes, each item of income, gain, loss and deduction of the Partnership shall be allocated among the Partners in the same manner as the corresponding items of Profits and Losses and specially allocated items are allocated for Capital Account purposes; provided, that in the case of any asset the Book Value of which differs from its adjusted tax basis for U.S. federal income tax purposes, income, gain, loss

and deduction with respect to such asset shall be allocated solely for income tax purposes in accordance with the principles of Sections 704(b) and (c) of the Code (in any manner determined by the General Partner) so as to take account of the difference between Book Value and adjusted basis of such asset.

(a) No Partner shall take, or cause to be taken, any action that would result in any other Partner having any personal liability for the obligations of the Partnership.

(b) To the fullest extent permitted by applicable law, no Partner or any Affiliate of any Partner or their respective members, officers, directors, employees, agents, stockholders or partners nor any Person who serves at the specific request of the General Partner on behalf of the Partnership as a partner, member, officer, director, employee or agent of any other entity (each, an “Indemnitee”) will be liable to the Partnership or to any Partner for any act performed or omission made by such Person in connection with this Agreement or the matters contemplated herein, unless such act or omission resulted from Gross Negligence, fraud, a willful breach of this Agreement or a willful illegal act. To the extent that an Indemnitee has, at law or in equity, duties and liabilities relating to the Partnership, any Limited Partner or any other Person bound by the terms of this Agreement, such Indemnitee, acting in accordance with this Agreement shall not, to the maximum extent permitted under applicable law, be liable to the Partnership or to any such Limited Partner or other Person for its good faith reliance on the provisions of this Agreement. To the extent that, at law or in equity, the General Partner has duties (including fiduciary duties) and liabilities relating thereto to the Partnership or to another Partner, the General Partner acting under the Agreement shall not be liable to the Partnership or to any such other Partner for its good faith reliance on the provisions of this Agreement. The provisions of this Agreement, to the extent that they expand or restrict the duties and liabilities of

the General Partner otherwise existing at law or in equity, are agreed by the Partners to be modified to the extent of such other duties and liabilities of the General Partner.

(c) To the maximum extent permitted under applicable law, whenever an Indemnitee is permitted or required to make a decision or take an action or omit to do any of the foregoing: (i) in its “sole discretion” or “discretion” or under a similar grant of authority or latitude or without an express standard of behavior (including, without limitation, standards such as “reasonable” or “good faith”), such Indemnitee shall be entitled to consider only such interests and factors, including its own, as it desires, and shall have no duty or obligation to consider any other interests or factors whatsoever, or (ii) with an express standard of behavior (including, without limitation, standards such as “reasonable” or “good faith”), then the Indemnitee shall comply with such express standard but, to the maximum extent permitted under applicable law, shall not be subject to any other or additional standard imposed by this Agreement or applicable law.

(d) Each Indemnitee may consult with legal counsel, financial advisors and accountants selected by it and any act or omission suffered or taken by it on behalf of the Partnership or in furtherance of the interests of the Partnership in good faith in reliance upon and in accordance with the advice of such counsel, financial advisors or accountants will be full justification for any such act or omission, and each such Indemnitee will be fully protected in so acting or omitting to act, provided that such counsel, financial advisors or accountants were selected with reasonable care.

(e) The Partnership shall, to the fullest extent permitted by law, indemnify and hold harmless any Indemnitee (and their respective heirs and legal and personal representatives) who was or is a party, or is threatened to be made a party, to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (including any action by or in the right of the Partnership), by reason of any actions or omissions or alleged acts or omissions arising out of such Person’s activities either on behalf of the Partnership or in furtherance of the interests of the Partnership or arising out of or in connection with the Partnership, against all claims, liabilities, damages, losses, costs and expenses (including amounts paid in satisfaction of judgments, in compromises and settlements, as fines and penalties and legal or other costs and reasonable expenses of investigating or defending against any claim or alleged claim) of any nature whatsoever, known or unknown, liquidated or unliquidated, that are incurred by any Indemnitee and arise out of or in connection with such action, suit or proceeding; provided, that such Person was not guilty of Gross Negligence, fraud, a willful breach of this Agreement or a willful illegal act; provided further, that any Person entitled to indemnification from the Partnership hereunder shall first seek recovery under any other indemnity or any insurance policies by which such Person is indemnified or covered, as the case may be, but only to the extent that the indemnitor with respect to such indemnity or the insurer with respect to such insurance policy provides (or acknowledges its obligation to provide) such indemnity or coverage on a timely basis, as the case may be, and, if such Person is other than the General Partner, such Person shall obtain the written consent of the General Partner prior to entering into any compromise or settlement which would result in an obligation of the Partnership to indemnify such Person. The General Partner shall have the Partnership purchase, at the Partnership’s expense, insurance to insure the Partnership and the Partners against liability in connection with the activities of the Partnership.

(f) The right to indemnification conferred in this Section 9.4 shall include the right to be paid or reimbursed by the Partnership the expenses incurred by a Person of the type entitled to be indemnified under Section 9.4(c) who was, is or is threatened to be made a named defendant or respondent in a proceeding in advance of the final disposition of the proceeding and without any determination as to the Person’s ultimate entitlement to indemnification. Such expenses shall, at the request of the Person entitled to be indemnified under Section 9.4(c), be advanced by the Partnership on behalf of such Person in advance of the final disposition of a proceeding so long as such Person shall have provided the Partnership with a written undertaking, by or on behalf of such Person, to repay all amounts so advanced if it shall ultimately be determined that such indemnified Person is not entitled to be indemnified under this Section 9.4 or otherwise.

(g) The right of any Indemnitee to the indemnification provided herein is cumulative of, and in addition to, any and all rights to which such Indemnitee may otherwise be entitled by contract or as a matter of law or equity, and extend to such Indemnitee’s successors, assigns and legal representatives.

TAXES

Section 11.1. Tax Matters Partner. The General Partner shall be the initial “tax matters partner” within the meaning of Section 6231(a)(7) of the Code (the “Tax Matters Partner”). The Tax Matters Partner shall determine in its reasonable discretion the appropriate treatment of each item of income, gain, loss, deduction and credit of the Partnership and the accounting methods and conventions under the tax laws of the United States, the several states and other relevant jurisdictions as to the treatment of any such item or any other method or procedure related to the preparation of such tax returns. The Tax Matters Partner shall have all of the rights, duties, powers and obligations provided for in Sections 6221 through 6232 of the Code. The Partnership intends to file as a partnership for U.S. federal, state and local income tax purposes, except where otherwise required by Law. All elections required or permitted to be made by the Partnership, and all other tax decisions and determinations relating to U.S. federal, state or local tax matters of the Partnership, shall be made by the Tax Matters Partner, in consultation with the Partnership’s attorneys and/or accountants. As appropriate, the Tax Matters Partner shall prepare a schedule allocating basis to all the assets of the Partnership under Code Sections 755 and 1060. Tax audits, controversies and litigations shall be conducted under the direction of the Tax Matters Partner. As soon as reasonably practicable after the end of each

taxable year but not later than 75 days after the end of each taxable year, the Partnership shall send to each Partner a copy of U.S. Internal Revenue Service Schedule K-1, and any comparable statements required by applicable state or local income tax Law, with respect to such taxable year. The Partnership also shall provide the Partners with such other information as may be reasonably requested for purposes of allowing the Partners to prepare and file their own tax returns. The Partnership shall bear the cost of the preparation and filing of its tax returns with respect to the Partnership and its Subsidiaries, but shall not bear any additional costs related primarily to any specific Partner. The Tax Matters Partner shall inform each other Partner of all significant matters that may come to its attention in its capacity as Tax Matters Partner by giving notice thereof as soon as reasonably practicable after becoming aware thereof and, within that time, shall forward to each other Partner copies of all significant written communications it may receive in that capacity.

Section 11.2. Information Rights.

(a) The Partnership agrees to provide to the Class A-1 Limited Partners such information as the Class A-1 Limited Partners reasonably request from time to time in order to (i) permit the Class A-1 Limited Partners to comply with any applicable information reporting obligations resulting from the Class A-1 Limited Partners’ investment in the Partnership and (ii) determine whether any majority-owned Subsidiary of the Partnership (based on vote or value) is or has been, or the consequences to the applicable Class A-1 Limited Partners, as the case may be, if any Subsidiary of the Partnership becomes, a “passive foreign investment company,” a “controlled foreign corporation,” a corporation whose income is required to be taken into account by the Class A-1 Limited Partners, and, at the request of the Class A-1 Limited Partners, cooperate with the Class A-1 Limited Partners in making, or permitting the applicable Class A-1 Limited Partners to make, any election permitted under the Code that does not have a material adverse tax effect to the other Partners. The Partnership shall also use reasonable commercial efforts to provide such information as the Class A-1 Limited Partners reasonably request for the foregoing purposes with respect to minority-owned Subsidiaries of the Partnership.

(b) The Partnership shall use good faith reasonable efforts to provide, at its expense, to OEP (i) the financial and tax information necessary to enable OEP to determine its (and its beneficial owners’) US taxable income (if any) (including gross income required to be recognized under Section 951 of the Code) derived from its investment for the applicable tax year (beginning with the 2006 tax year, but only if, in the reasonable determination of OEP, any of the beneficial owners of OEP qualifies as a “United States shareholder” of the Partnership, as defined in Section 951(b) of the Code) and foreign tax credits no later than May 31 of each year and (ii) any information required to be included in US federal income tax returns, forms, statements and related disclosures that are required to be filed by or on behalf of OEP and its respective beneficial owners with respect to its investment no later than June 30 of each year. The Partnership shall also (A) make a determination each year, at its expense, of whether the Partnership or any of its direct or indirect subsidiaries qualify as “passive foreign investment companies” within the meaning of Section 1297 of the Code for the taxable year and, if relevant, (B) use good faith reasonable efforts to (I) communicate the determination to OEP in writing no later than May 31 of the succeeding year and (II) provide OEP with the information described in the preceding sentence. The Partnership shall consider and use commercially reasonable efforts to implement (at OEP’s expense) proposals by OEP to enhance the tax position of its affiliates in

connection with its investment in the Partnership, provided that the proposals are not disadvantageous to the Partnership (or any of its beneficial owners) or the Partnership or any of its direct or indirect subsidiaries (determined at the sole discretion of the GP).

Section 11.3. Tax Withholding. To the extent the Partnership is required by law to withhold or to make tax payments on behalf of or with respect to any Partner (“Tax Advances”), the Partnership may withhold such amounts and make such tax payments as so required. All Tax Advances made on behalf of a Partner shall be repaid by reducing the amount of the current or next succeeding distribution or distributions which would otherwise have been made to such Partner or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation otherwise payable to such Partner. If a distribution to a Partner is actually reduced as a result of a Tax Advance, for all other purposes of this Agreement such Partner shall be treated as having received the amount of the distribution that is reduced by the Tax Advance. Each Partner hereby agrees to indemnify and hold harmless the Partnership and the other Partners from and against any liability (including, without limitation, any liability for taxes, penalties, additions to tax or interest) with respect to income attributable to or distributions or other payments to such Partner.

(a) Except as otherwise provided in a Management Equity Award Agreement, if a Management Limited Partner’s Services to the Partnership and its Subsidiaries terminate for any reason (including death or Disability) (a “Termination Event”), the Partnership shall have the

right but not the obligation to purchase, from time to time after such Termination Event, for a period of 200 days following the later of (x) the Termination Event and (y) with respect to Management Interests which are Vested Interests, the date such Management Interests become Vested Interests (the “Call Option Period”), the Management Interests held by such Management Limited Partner. To exercise such purchase right with respect to a Management Limited Partner, the Partnership shall deliver to such Management Limited Partner prior to the expiration of the Call Option Period a written notice specifying the number and class of Interests with respect to which the Partnership has elected to exercise such purchase right, whereupon such Management Limited Partner shall be required to sell to the Partnership, the Management Interests specified in such notice, at a price per Management Interest equal to the applicable purchase price determined pursuant to Section 12.2(c).

(b) If upon expiration of the Call Option Period, the Partnership has not purchased all of a terminated Management Limited Partner’s Management Interests which are Vested Interests, the Partnership shall on or before the expiration of the Call Option Period provide written notice to each Partner that is a member of a Sponsor Group (collectively, the “Other Partners”) of (i) its decision not to purchase some or all of such Management Interests and (ii) the number and class of such Management Interests which the Partnership did not elect to purchase, and the Other Partners shall have the right to purchase all or a portion of such remaining Management Interests which are Vested Interests at a price per Management Interest equal to the applicable purchase price determined pursuant to Section 12.2(c). The Other Partners’ rights to purchase such Management Interests and such Management Limited Partner’s corresponding obligation to sell such Management Interests shall terminate on the 60th day following the expiration of the Call Option Period. Each of the Other Partners that elects to exercise such purchase right shall provide written notice to the Partnership prior to the 60thday following the expiration of the Call Option Period specifying that the number of such Management Interests it wishes to purchase (and, if the aggregate number of Equity Incentives Interests specified in such notices exceeds the number of Management Interests available, the number of Management Interests which each Other Partner shall be entitled to purchase shall be reallocated in proportion to each such Other Partner’s Ownership Percentage). Upon receipt of the Other Partners’ notices, the Partnership will notify such Management Limited Partners of the Other Partners’ elections and such Management Limited Partner will be obligated to sell to the Other Partners the number of such Management Interests determined in accordance with this Section 12.2(b).

(c) Call Values. Except as otherwise provided in a Management Equity Award Agreement:

(i) Unvested Interests; Any Termination. Upon a termination of a Management Limited Partner’s Services to the Partnership and its Subsidiaries for any reason (including death or Disability), the purchase price for the Management Interests which are Unvested Interests, to the extent the forfeiture provisions set forth in Section 12.1(b) do not apply or are not enforceable, will be $1 in the aggregate (or the lowest price permitted by applicable Law).

(ii) Vested Interests; Cause Termination. Upon a termination of a Management Limited Partner’s Services by the Partnership and its Subsidiaries for Cause

(iii) Vested Interests; Other Termination. Upon a termination of a Management Limited Partner’s Services to the Partnership and its Subsidiaries for any reason other than a termination by the Partnership or its Subsidiaries for Cause (as defined in the applicable Management Equity Award Agreement), the purchase price for the Management Interests which are Vested Interests will be Fair Market Value (determined pursuant to Section 12.4 and, in the case of a purchase by the Partnership pursuant to Section 12.2(a), as of the date on which the Partnership exercised its call right pursuant to Section 12.2(a) or, in the case of a purchase by any Other Partner pursuant to Section 12.2(b), as of the 60th day following the expiration of the applicable Call Option Period (such date, the “Price Determination Date”)).

(d) The closing of the purchase of the Management Interests pursuant to Section 12.2(a) or 12.2(b) shall occur at such time and place as the parties to such purchase shall agree, and in any event within 45 days of the Price Determination Date; provided that if such purchase is subject to any prior regulatory approval, then such 45-day period shall be extended until the expiration of 10 Business Days after all such approvals shall have been received. At such closing, the Management Limited Partner shall deliver certificates representing the Management Interests (or other applicable transfer instruments), duly endorsed for transfer and accompanied by all requisite transfer taxes, if any, and such Management Interests shall be free and clear of any liens, and the transferring Management Limited Partner shall so represent and warrant, and shall further represent and warrant that it is the sole beneficial and record owner of such Management Interests with the full right, power and authority to convey the Management Interests to the purchaser. At such closing, all of the parties to the transaction shall execute such additional documents as are otherwise necessary or appropriate. The Management Interests may be purchased (i) by delivery of funds deposited into an account designated by the Management Limited Partner selling such Management Interests, a bank cashier’s check, a certified check or a company check of the purchaser for the purchase price, (ii) if the purchaser is the Partnership and it or its Subsidiaries are prohibited from paying cash by any financing arrangements of the Partnership and unable to pay the purchase price in shares as described in clause (iii) below, by a note of the Partnership payable in installments over a period of up to five (5) years from the date of issuance of such note, having a principal amount equal to the applicable purchase price, bearing interest at a market borrowing rate for similarly situated companies of similar credit quality in effect from time to time (which note shall be a general, senior unsecured obligation of the Partnership or a Subsidiary of the Partnership that holds all or substantially all of the assets of the Partnership), or (iii) if a Qualified Public Offering has occurred, by delivery of a number of shares of the IPO Corporation equal to the aggregate purchase price of the Management Interests being purchased divided by the closing price on the applicable exchange on which such share trade as of the trading day immediately prior to the day of delivery thereof to the Management Limited Partner, rounded down to the nearest whole number of shares. The Partnership shall notify the Management Limited Partners in writing of the method by which it has elected to purchase the Management Interests at least 3 Business Days prior to the closing of such purchase. The parties hereto acknowledge that the Partnership may be unable to pay with Shares

to the extent it is unable to deliver such securities pursuant to an exemption from registration under the Securities Act and any applicable state securities laws or pursuant to a registration statement on Form S-3 or Form S-8.

(e) Notwithstanding anything to the contrary elsewhere herein, the Partnership shall not be obligated to purchase any Management Interests at any time pursuant to this Section 12.2, regardless of whether it has delivered a notice of its election to purchase any such Management Interests, (i) to the extent that (A) the purchase of such Management Interests (together with any other purchases of Management Interests pursuant to this Article XII, or pursuant to similar provisions in any other agreements with other investors, of which the Partnership has at such time been given or has given notice) or (B) in the event of an election to purchase such Management Interests with shares of the IPO Corporation, the issuance of such shares by the IPO Corporation or the distribution of such shares of the IPO Corporation to the applicable Management Limited Partner(s) would result (x) in a violation of any Law (including any unavailability of a registration statement or exemption from registration necessary to allow delivery of shares to the applicable Management Limited Partner(s)), (y) after giving effect thereto (including any dividends or other distributions or loans from a Subsidiary of the Partnership to the Partnership in connection therewith), in a default or event of default under any financing agreement of the Partnership or its Subsidiaries (a “Financing Default”) or (z) in the Partnership being required to disgorge any profit to the IPO Corporation pursuant to Section 16(b) of the Exchange Act, (ii) if immediately prior to such purchase of Management Interests, issuance or purchase of shares of the IPO Corporation, as the case may be, there exists a Financing Default which prohibits such issuance or purchase (including any dividends or other distributions or loans from a Subsidiary of the Partnership to the Partnership in connection therewith), or (iii) if the Partnership does not have funds available to effect such purchase of Management Interests. The Partnership shall within 15 days of learning of any such fact so notify the Members in writing that it is not obligated to purchase such Management Interests, whereupon Sections 12.2(b) and 12.2(c) shall apply to such Management Interests as if the Partnership had never delivered a notice electing to purchase such Management Interests (except that each reference to “the 60th day following the expiration of the Call Option Period” in Section 12.2(b) shall be deemed a reference to “the 60th day following the delivery by the Partnership of the notice referred to in Section 12.2(e)” and the definition of “Price Determination Date” shall be deemed modified in a corresponding manner). Notwithstanding the foregoing, the Partnership shall use reasonable efforts to cause its Subsidiaries to distribute cash necessary to satisfy its obligations in respect of Section 12.2(d) and Section 12.2(e).

Section 12.3. Put Rights.

(a) Except as otherwise provided in a Management Equity Award Agreement, if a Management Limited Partner’s Services to the Partnership and its Subsidiaries terminate as a result of death of Disability (a “Put Termination Event”), the Management Limited Partner (or its estate or heirs) shall have the right but not the obligation to require the Partnership to purchase, from time to time after such Put Termination Event, for a period of 200 days following the later of (x) Put Termination Event and (y) with respect to Management Interests which are Vested Interests, the date such Management Interests become Vested Interests (the “Put Option Period”), all (but not less than all) of the Management Interests held by such Management Limited Partner; provided that the General Partner may require that the exercise be delayed until the 181^st day

following the later of the Put Termination Event and the date such Management Interests become Vested Interests if deferring such exercise would avoid an adverse accounting impact to the Partnership or its Subsidiaries. To exercise such purchase right, the Management Limited Partner (or its estate or heirs) shall deliver to the Partnership prior to the expiration of the Put Option Period a written notice specifying its election to exercise its rights under this Section 12.3, whereupon such Management Limited Partner (or its estate or heirs) shall be required to sell to the Partnership all of its Management Interests, at a price per Management Interest equal to the applicable purchase price determined pursuant to Section 12.2(c).

(b) The closing of the purchase of the Management Interests pursuant to Section 12.3(a) shall occur at such time and place as the parties to such purchase shall agree, and in any event within 45 days of the Price Determination Date; provided that if such purchase is subject to any prior regulatory approval, then such 45-day period shall be extended until the expiration of 10 Business Days after all such approvals shall have been received. At such closing, the Management Limited Partner (or its estate or heirs) shall deliver certificates representing the Management Interests (or other applicable transfer instruments), duly endorsed for transfer and accompanied by all requisite transfer taxes, if any, and such Management Interests shall be free and clear of any liens, and the transferring Management Limited Partner (or its estate or heirs) shall so represent and warrant, and shall further represent and warrant that it is the sole beneficial and record owner of such Management Interests with the full right, power and authority to convey the Management Interests to the Partnership. At such closing, all of the parties to the transaction shall execute such additional documents as are otherwise necessary or appropriate. The Management Interests may be purchased through any of the means described in, and subject to the terms and conditions of, Section 12.2(d).

(c) Notwithstanding anything to the contrary elsewhere herein, the Partnership shall not be obligated to purchase any Management Interests at any time pursuant to this Section 12.3 (i) to the extent that (A) the purchase of such Management Interests (together with any other purchases of Management Interests pursuant to this Article XII, or pursuant to similar provisions in any other agreements with other investors, of which the Partnership has at such time been given or has given notice) or (B) in the event of an election to purchase such Management Interests with shares of the IPO Corporation, the issuance of such shares by the IPO Corporation or the distribution of such shares of the IPO Corporation to the applicable Management Limited Partner(s) would result (x) in a violation of any Law (including any unavailability of a registration statement or exemption from registration necessary to allow delivery of shares to the applicable Management Limited Partner(s)), (y) after giving effect thereto (including any dividends or other distributions or loans from a Subsidiary of the Partnership to the Partnership in connection therewith), in a Financing Default or (z) in the Partnership being required to disgorge any profit to the IPO Corporation pursuant to Section 16(b) of the Exchange Act, (ii) if immediately prior to such purchase of Management Interests, issuance or purchase of shares of the IPO Corporation, as the case may be, there exists a Financing Default which prohibits such issuance or purchase (including any dividends or other distributions or loans from a Subsidiary of the Partnership to the Partnership in connection therewith), or (iii) if the Partnership does not have funds available to effect such purchase of Management Interests. The Partnership shall within 15 days of learning of any such fact so notify the Members in writing that it is not obligated to purchase such Management Interests, whereupon Sections 12.3(b) and 12.3(c) shall apply to such Management Interests as if the

Management Limited Partner (or its estate or heirs) had never delivered a notice electing to require the Partnership to purchase such Management Interests. Notwithstanding the foregoing, the Partnership shall use reasonable efforts to cause its Subsidiaries to distribute cash necessary to satisfy its obligations in respect of Section 12.3.

(d) The provisions of this Section 12.3 shall terminate upon a Qualified Public Offering.

Section 12.4 Fair Market Value. “Fair Market Value” for the Management Interests to be purchased under Section 12.2 or Section 12.3 will mean (i) if there is a public market for the Interests or shares of IPO Corporation on such date, the value for such Management Interests implied by the average of the high and low closing bid prices of such Interests or shares on the stock exchange on which the equity is principally trading or (ii) if there is no public market for the equity on such date, the value for such Management Interests implied by an enterprise value for the Partnership of 7.5 times the trailing 12 months’ EBITDA, as determined by the General Partner in good faith in consultation with the Chief Executive Officer and Chief Financial Officer of the Partnership’s principal operating Subsidiary.

Section 12.5. Voting; Power of Attorney.

(a) Except as otherwise provided herein or in the Partnership Act, only the holders of Class A Interests will be entitled to vote on any matters requiring a vote, consent or other action of the Limited Partners. Any action shall be authorized if the affirmative vote of the holders of a majority of the Class A Interests present at a meeting at which a quorum is present shall be obtained. Prior to the Lapse Date, to the extent any class of Interests is required or eligible to vote with respect to any matter (including Class A Interests or any other class), each Management Limited Partner shall vote all of its eligible Management Interests in any manner directed by the General Partner.

(b) Each Management Limited Partner hereby constitutes and appoints the General Partner (and any member of the board of directors of the General Partner acting at the direction of a valid majority of such board), with full power of substitution, as such Person’s true and lawful agent and attorney in fact, with full power and authority in such Person’s name, place and stead, (i) to, prior to the Lapse Date, vote for or against in respect of any matter pursuant to which such Management Limited Partner is eligible to vote its Interests and (ii) to execute, swear to, acknowledge, deliver, file and record in the appropriate public offices (A) this Agreement, all certificates and other instruments and all amendments thereof in accordance with the terms hereof which the General Partner or such member deems appropriate or necessary to form, qualify, or continue the qualification of, the Partnership as a limited partnership in the Cayman Islands and in all other jurisdictions in which the Partnership may conduct business or own property; (B) all instruments which the General Partner or such member deems appropriate or necessary to reflect any amendment, change, modification or restatement of this Agreement in accordance with its terms; (C) all conveyances and other instruments or documents which the General Partner or such member deems appropriate or necessary to reflect the dissolution of the pursuant to the terms of this Agreement, including a certificate of cancellation; and (D) all instruments relating to the admission, withdrawal or substitution of any Partner pursuant to the terms hereof. The foregoing power of attorney is irrevocably given by way of securing such

Management Limited Partner’s obligations hereunder, and shall survive and not be affected by the death, disability, incapacity, dissolution, bankruptcy, insolvency or termination of any Management Limited Partner and the Disposition of all or any portion of such Management Limited Partner’s Interests and shall extend to such Management Limited Partner’s heirs, successors, assigns and personal representatives.

ARTICLE XIII

BOOKS AND BANK ACCOUNTS

Section 13.1. Maintenance of Books. The General Partner shall keep or cause to be kept at the Partnership’s principal place of business complete and accurate books and records of the Partnership and supporting documentation of the transactions with respect to the conduct of the Partnership’s business. The Partnership’s financial books and records shall be maintained on a full cost accounting basis unless otherwise agreed by the General Partner. The records shall include, but not be limited to, complete and accurate information regarding the state of the business and financial condition of the Partnership; a copy of this Agreement and all amendments thereto; the current list of the names and last known business, residence, or mailing addresses of all Partners; and the Partnership’s U.S. federal, state, and local tax returns for the Partnership’s six most recent tax years.

Section 13.2. Accounts. The General Partner shall maintain a register of the Partners’ interests in the Partnership at the registered office of the Partnership, setting forth the name and address of each Partner, the amount and date of each Capital Contribution by a Partner and the amount and date of any payment representing a return of any part of the contribution of any Partner and shall maintain a register of mortgages created by the Limited Partners over their interest in the Partnership at the registered office of the Partnership in accordance with Section 7(7)(b) of the Partnership Act.

ARTICLE XIV

DISSOLUTION, WINDING-UP AND TERMINATION

Section 14.1. Dissolution of the Partnership.

(a) The Partnership shall be dissolved, and its affairs shall be wound up and a Section 15 Notice of Dissolution shall be filed with the Registrar pursuant to the Partnership Act upon the first to occur of the following (each a “Dissolution Event”): (i) the General Partner determines to dissolve the Partnership, (ii) at any time when there are no Limited Partners or (iii) the entry of a decree of judicial dissolution of the Partnership under the Partnership Act. The dissolution, resignation, expulsion or bankruptcy of any Limited Partner or, save as provided below, the General Partner, shall not cause the dissolution of the Partnership.

(b) The removal, withdrawal, bankruptcy, insolvency, termination or dissolution of the last remaining General Partner of the Partnership being either an individual resident in the Cayman Islands or a company registered under the Companies Law (as revised) of the

Cayman Islands or registered pursuant to Part IX of the Companies Law (as revised) of the Cayman Islands or a partnership registered pursuant to section 9(1) of the Partnership Act shall dissolve the partnership unless the Limited Partners unanimously agree to continue the Partnership and appoint a new General Partner who is either an individual resident in the Cayman Islands or a company registered under the Companies Law (as revised) of the Cayman Islands or registered pursuant to Part IX of the Companies Law (as revised) of the Cayman Islands or a partnership registered pursuant to section 9(1) of the Partnership Act within 90 days thereof.

Section 14.2. Winding-up and Termination. On the occurrence of a Dissolution Event, the General Partner (or, if there is no General Partner, the Limited Partners holding a majority of the outstanding Class A Interests, taken together as a single class) shall select one or more Persons to act as liquidator or may itself act as liquidator. The liquidator shall proceed diligently to wind up the affairs of the Partnership and make final distributions as provided herein and in the Partnership Act. The costs of winding up shall be borne as a Partnership expense, including reasonable compensation to the liquidator. Until final distribution, the liquidator shall continue to operate the Partnership properties with all of the power and authority of the General Partner. Subject to the terms in the Partnership Act, the steps to be accomplished by the liquidator are as follows:

(a) as promptly as possible after dissolution and again after final winding up, the liquidator shall cause a proper accounting to be made by a recognized firm of certified public accountants of the Partnership’s assets, liabilities, and operations;

(b) the liquidator shall pay, satisfy or discharge from Partnership funds all of the debts, liabilities and obligations of the Partnership or otherwise make adequate provision for payment and discharge thereof (including the establishment of a cash escrow fund for contingent liabilities in such amount and for such term as the liquidator may reasonably determine); and

(c) all remaining assets of the Partnership shall be distributed to the Partners as follows; provided, however, that the liquidator shall use reasonable best efforts to distribute cash to Partners:

(i) the liquidator may sell any or all Partnership property, including to Partners, and any resulting gain or loss from each sale shall be computed and allocated to the Capital Accounts of Partners in accordance with the provisions of Article VIII;

(ii) with respect to all Partnership property that has not been sold, the fair market value of that property shall be determined and the Capital Accounts of Partners shall be adjusted to reflect the manner in which the unrealized income, gain, loss, and deduction inherent in property that has not been reflected in the Capital Accounts previously would be allocated among Partners if there were a taxable disposition of that property for the fair market value of that property on the date of distribution; and

(iii) Partnership property shall be distributed among the Partners in accordance with Section 7.1, and those distributions shall be made by the end of the

taxable year of the Partnership during which the liquidation of the Partnership occurs (or, if later, 90 days after the date of the liquidation).

All distributions in kind to Partners shall be made subject to the liability of each distributee for costs, expenses, and liabilities theretofore incurred or for which the Partnership has committed prior to the date of termination and those costs, expenses, and liabilities shall be allocated to the distributee pursuant to this Section 14.2. The distribution of cash and/or property to a Partner in accordance with the provisions of this Section 14.2 constitutes a complete return to the Partner of its Capital Contributions and a complete distribution to the Partner of its Interests of all the Partnership’s property and constitutes a compromise to which all Partners have consented. To the extent that a Partner returns funds to the Partnership, it has no claim against any other Partner for those funds.

Section 14.3. Deficit Capital Accounts. No Partner shall be required to pay to the Partnership, to any other Partner or to any third party any deficit balance which may exist from time to time in the Partner’s Capital Account.

Section 14.4. Dissolution. On completion of the distribution of Partnership assets as provided herein, the General Partner or the liquidators (or such other Person or Persons as the Partnership Act may require or permit) shall file such documents and take such other actions as may be necessary to terminate the existence of the Partnership. Upon satisfaction of all applicable matters required under the Partnership Act, the existence of the Partnership shall cease, except as may be otherwise provided by the Partnership Act or other applicable Law.

ARTICLE XV

WITHDRAWAL OF PARTNERS

Section 15.1. Withdrawal of General Partner. The General Partner covenants and agrees that it will not withdraw as the General Partner of the Partnership for the term of the Partnership except as permitted under this Agreement.

Section 15.2. Withdrawal of Limited Partners. No Limited Partner shall have any right to withdraw from the Partnership except as permitted under this Agreement. No Limited Partner shall be entitled to receive any distribution from the Partnership for any reason or upon any event except as expressly set forth in Articles V, VII and XV.

ARTICLE XVI

GENERAL PROVISIONS

Section 16.1. Offset. Whenever the Partnership is to pay any sum to any Partner, any amounts that such Partner, in its capacity as a Partner, owes the Partnership may be deducted from that sum before payment.

Section 16.2. Notices. Except as expressly set forth to the contrary in this Agreement, all notices, requests or consents provided for or required to be given hereunder shall

be in writing and shall be deemed to be duly given if personally delivered, telecopied and confirmed, or mailed by certified mail, return receipt requested, or nationally recognized overnight delivery service with proof of receipt maintained, at the following addresses (or any other address that any such party may designate by written notice to the other parties):

(i) if to the Partnership or the General Partner, at the address of the General Partner’s principal executive offices; and

(ii) if to a Partner (other than a Management Limited Partner), to the address given for the Partner on Schedule A hereto;

(iii) if to a Management Limited Partner, to the address given for the Partner on the applicable Management Equity Award Agreement (or such other address on the payroll records of the Partnership or its Subsidiaries; and

(iv) if to a holder of Interests that has not been admitted as a Partner, to the address given for such holder in an Addendum Agreement.

Any such notice shall, if delivered personally, be deemed received upon delivery; shall, if delivered by telecopy, be deemed received on the first business day following confirmation; shall, if delivered by nationally recognized overnight delivery service, be deemed received the first business day after being sent; and shall, if delivered by mail, be deemed received upon the earlier of actual receipt thereof or five business days after the date of deposit in the United States mail.

(b) Whenever any notice is required to be given by Law, this Agreement, a written waiver thereof, signed by the Person entitled to notice, whether before or after the time stated therein, shall be deemed equivalent to the giving of such notice.

Section 16.3. Entire Agreement; Supersede. This Agreement and the other Transaction Documents constitute the entire agreement of the Partners and their Affiliates relating to the Partnership and supersede all prior contracts or agreements with respect to the Partnership, whether oral or written.

Section 16.4. Effect of Waiver or Consent. A waiver or consent, express or implied, to or of any breach or default by any Person in the performance by that Person of its obligations with respect to the Partnership is not a consent or waiver to or of any other breach or default in the performance by that Person of the same or any other obligations of that Person with respect to the Partnership. Failure on the part of a Person to complain of any act of any Person or to declare any Person in default with respect to the Partnership, irrespective of how long that failure continues, does not constitute a waiver by that Person of its rights with respect to that default until the applicable statute-of-limitations period has run.

Section 16.5. Amendment or Restatement. This Agreement (including any Exhibit or Schedule hereto) may not be amended, modified, supplemented or restated, nor may any provisions of this Agreement be waived, without a written instrument adopted, executed and agreed to by the General Partner; provided, however, that (a) any such amendment, modification,

supplement, restatement or waiver that would disproportionately and adversely affect the rights of any Partner hereunder, in its capacity as a Partner, as the case may be, without similarly affecting the rights hereunder of all Partners of the same class, in their capacities as Partners, as the case may be, shall not be effective as to such Partner without such Partner’s prior written consent and, provided, further, Article IV, Sections 5.5, 9.4, 9.5, Article X and Sections 16.5, 16.6, 16.8 or the Definitions of “Affiliate”, “Permitted Transferee”, “Qualified Public Offering” (with respect to the size of the offering) and “Subsidiary” and the terms of the Interests held by the TCV Group and the OEP Group may not be amended, modified, supplemented, restated or waived in a manner that is adverse to TCV or OEP without the prior written consent of TCV and OEP, provided, further that the General Partner may not be replaced and no new General Partner may be appointed without the consent of TCV and OEP. Notwithstanding anything to the contrary in this Section 16.5, if the provisions of Proposed Treasury Regulation Section 1.83-3 and related sections and the proposed Revenue Procedure described in IRS Notice 2005-43, as proposed by the Internal Revenue Service on May 24, 2005, or provisions similar thereto, are adopted as final (or temporary) rules (the “New Rules”), the General Partner is authorized to make such amendments to this Agreement (including provision for any safe harbor election authorized by the New Rules) as the General Partner may determine to be necessary or advisable to comply with or reflect the New Rules. Except as required by Law, no amendment, modification, supplement, discharge or waiver of or under this Agreement shall require the consent of any person not a party to this Agreement.

Section 16.6. Termination. This Agreement shall terminate upon the earlier to occur of (i) the consummation of an Approved Sale of the entire Partnership pursuant to Section 4.5 and the distribution of the proceeds therefrom, (ii) the consummation of a Dissolution Event, (iii) upon the written agreement of the Partners, and (iv) the consummation of a firm commitment underwritten public offering by the IPO Corporation of common stock pursuant to an effective registration statement under the Securities Act.

Section 16.7. Binding Effect. Subject to the restrictions on Dispositions set forth in this Agreement, this Agreement shall be binding upon and shall inure to the benefit of the Partnership and each Partner and their respective heirs, permitted successors, permitted assigns, permitted distributees and legal representatives; and by their signatures hereto, the Partnership and each Partner intends to and does hereby become bound. Nothing expressed or mentioned in this Agreement is intended or shall be construed to give any Person other than the parties hereto and their respective permitted successors and assigns any legal or equitable right, remedy or claim under, in or in respect of this Agreement or any provision herein contained.

Section 16.8. Governing Law; Severability; Limitation of Liability.

(a) This Agreement shall be governed by and construed in accordance with Cayman Islands law.

(b) In the event of a direct conflict between the provisions of this Agreement and any mandatory, non-waivable provision of the Partnership Act, such provision of the Partnership Act shall control. If any provision of the Partnership Act provides that it may be varied or superseded in the limited partnership agreement (or otherwise by agreement of the

partners of a limited partnership), such provision shall be deemed superseded and waived in its entirety if this Agreement contains a provision addressing the same issue or subject matter.

(c) If any provision of this Agreement is held to be illegal, invalid or unenforceable under present or future laws effective during the term of this Agreement, such provision shall be fully severable; this Agreement shall be construed and enforced as if such illegal, invalid, or unenforceable provision had never comprised a part of this Agreement; and the remaining provisions of this Agreement shall remain in full force and effect and shall not be affected by the illegal, invalid or unenforceable provision or by its severance from this Agreement. Furthermore, in lieu of each such illegal, invalid or unenforceable provision, there shall be added automatically as a part of this Agreement a provision as similar in terms to such illegal, invalid or unenforceable provision as may be possible and be legal, valid and enforceable.

(d) Neither the Partnership nor any Partner shall be liable to any of the other such Persons for punitive, special, exemplary or consequential damages, including damages for loss of profits, loss of use or revenue or losses by reason of cost of capital, arising out of or relating to this Agreement or the transactions contemplated hereby, regardless of whether based on contract, tort (including negligence), strict liability, violation of any applicable deceptive trade practices act or similar Law or any other legal or equitable principle, and the Partnership and each Partner releases each of the other such Persons from liability for any such damages.

Section 16.9. Further Assurances. In connection with this Agreement and the transactions contemplated hereby, the Partnership and each Partner shall execute and deliver all such future instruments and take such other and further action as may be reasonably necessary or appropriate to carry out the provisions of this Agreement and the intention of the parties as expressed herein.

Section 16.10. Indemnification. The Partnership shall at all times maintain or cause to be maintained directors and officers’ liability insurance and indemnification policy covering the Partnership and its Subsidiaries and the General Partner which, in the good faith business judgment of the General Partner, is reasonable (x) for a company comparable in size to the Partnership and its Subsidiaries and (y) for substantially similar companies in the industry in which the Partnership and its Subsidiaries operate.

Section 16.11. Counterparts. This Agreement may be executed in any number of counterparts (including facsimile counterparts), all of which together shall constitute a single instrument. It shall not be necessary that any counterpart be signed by each of the Partners so long as each counterpart shall be signed by one or more of the Partners and so long as the other Partners shall sign at least one counterpart which shall be delivered to the Partnership.

Section 16.12. Other Covenants.

(a) Each Partner acknowledges and agrees that, upon any Dissolution Event or any Approved Sale of all of the Interests in the Partnership in accordance with this Agreement, the receipt of proceeds by the Partners with respect to their Interests shall be in accordance with Article VII.

(b) Each Partner entitled to vote on matters submitted to a vote of the Partners, as the case may be, agrees to vote the Interests owned by such Partner upon all matters arising under this Agreement submitted to a vote of the Partners, as the case may be, in a manner that will implement the terms of this Agreement.

Section 16.13. VCOC; Condition to Funding.

(a) In the event TDS Investor (Cayman) L.P. ceases to qualify as an “operating company” as defined in the first sentence of 29 C.F.R.

Section 2510.3-101(d) shall continue to qualify as a “venture capital investment” within the meaning of 29 C.F.R. Section 2510.3-101(d).

(b) Neither Blackstone Participation Partnership (Cayman) V L.P. nor Blackstone Capital Partners (Cayman) V-S L.P. will be required to fund any payment to the Partnership or any of their Subsidiaries until such time as TDS Investor (Cayman) L.P. qualifies as an “operating company” within the meaning of the first sentence of Section 2510.3-101(d)(1) of the U.S. Department of Labor regulations codified at 29 C.F.R. Section 2510.3-101.
