(b)           Interest
Certificates.  Ownership of Interests
may be evidenced by certificates, but shall be exclusively determined by entry
in the Register of Partners.  Each
Interest certificate and the Register of Partners shall bear a legend on the
face thereof in the following form:

“TRANSFER IS SUBJECT TO RESTRICTIVE
LEGENDS ON BACK.”

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

“THIS SECURITY HAS NOT BEEN
REGISTERED UNDER THE UNITED STATES SECURITIES ACT OF 1933, AS AMENDED (THE
“SECURITIES ACT”), AND MAY NOT BE OFFERED OR SOLD, UNLESS IT HAS BEEN
REGISTERED UNDER THE SECURITIES ACT OR UNLESS AN EXEMPTION FROM REGISTRATION IS
AVAILABLE (AND, IN SUCH CASE, AN OPINION OF COUNSEL REASONABLY SATISFACTORY TO
THE GENERAL PARTNER SHALL HAVE BEEN DELIVERED TO THE PARTNERSHIP TO THE EFFECT
THAT SUCH OFFER OR SALE IS NOT REQUIRED TO BE REGISTERED UNDER THE SECURITIES
ACT).  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. AND (Z) THE OTHER TRANSACTION
DOCUMENTS DESCRIBED IN THE PARTNERSHIP AGREEMENT, IN EACH SUCH CASE, AS AMENDED
FROM TIME TO TIME, COPIES OF WHICH MAY BE OBTAINED FROM THE PARTNERSHIP AT ITS
PRINCIPAL EXECUTIVE OFFICES.”

(c)           Conformed copies of this Agreement
shall be kept with the records of the Partnership by the General Partner at its
principal executive offices.  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

 4
 

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legend is no longer applicable.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.  Any reference in this
Agreement to Schedule A shall be deemed to be a reference to Schedule A as
amended and in effect from time to time.

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

 5
 

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.  Immediately upon any such
Disposition, the General Partner shall cause such Partner’s name to be removed
from the Register of Partners.

Section 3.6.   Spouses of Partners.  Spouses of the Partners that are natural
persons do not become Partners as a result of such marital relationship.  Each spouse of a Partner shall be required to
execute a Spousal Agreement in the form of Exhibit B to evidence their
agreement and consent to be bound by the terms and conditions of this Agreement
as to their interest, whether as community property or otherwise, if any, in
the Interests owned by such Partner.

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

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.

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.

(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

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

 7
 

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

 8
 

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.  

 9
 

(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

 10
 

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.

 11
 

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

 12
 

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

 13
 

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).

 14
 

(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

 15
 

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.

respects as offsets against subsequent distributions pursuant to Section 7.1.

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

 24
 

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.

 25
 

(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.

ARTICLE IX

(f)            Each Partner agrees
that, except as otherwise expressly provided herein and to the fullest extent
permitted by applicable law, any action of or relating to the Partnership by
the General Partner as provided herein shall bind each Partner.

Section 9.2.   Reliance by
Third Parties.  Notwithstanding any other provision of this
Agreement to the contrary, any Person dealing with the Partnership shall be
entitled to rely exclusively on the representations of the General Partner as
to its power and authority to enter into arrangements and shall be entitled to
deal with the General Partner as if it were the sole party in interest therein,
both legally and beneficially.  In no event
shall any Person dealing with the General Partner or the General Partner’s
representative with respect to any business or property of the Partnership be
obligated to ascertain that the terms of this Agreement have been complied
with, or be obligated to inquire into the necessity or expedience of any act or
action of the General Partner or the General Partner’s representative; and
every Contract or other document executed by the General Partner or the General

and/or delivery thereof this Agreement was in full force and effect, (b) such
instrument or document was duly executed in accordance with the terms and
provisions of this Agreement and is binding upon the Partnership and (c) the
General Partner or the General Partner’s representative was duly authorized and

and on behalf of the Partnership.

 27
 

Section 9.3.   Compensation and Reimbursement of
General Partner.

(a)           Except as provided in this Section
9.3 or otherwise in this Agreement, the General Partner shall not be

(b)           The General Partner shall be
reimbursed for all expenses, disbursements and advances incurred or made on
behalf of the Partnership, and other expenses necessary or appropriate to the
conduct of the Partnership’s business and allocable to the Partnership.

Section 9.4.   Certain Duties and Obligations of the
Partners;
Exculpation; Indemnity.

(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.

 28
 

(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

 29
 

entitled by contract or as a
matter of law or equity, and extend to such Indemnitee’s successors, assigns
and legal representatives.

Section 9.5.  
No Recourse Agreement.  Neither the Partnership nor any of its
Subsidiaries shall enter into any agreement which shall provide for recourse to
any Limited Partner or, without its consent, the General Partner.  No recourse to (a) any assets or properties
of any members, partners or shareholders of any Limited Partner (or any person
that controls such member, partner or shareholder within the meaning of Section
15 of the Securities Act or Section 20 of the Securities Exchange Act of 1934,
as amended, and the rules and regulations promulgated thereunder (the “Exchange
Act”)), (b) any Affiliate of any Limited Partner or (c) any incorporators,
officers, directors, partners, members or employees of any Limited Partner
shall be had and no judgment relating to the obligations of any Limited Partner
under this Agreement or the Transaction Documents (except to the extent any
such Person expressly is individually liable thereunder) or for any payment
obligations under this Agreement or the Transaction Documents (except to the
extent any such Person expressly is individually liable thereunder), or any
part thereof, or for any claim based thereon or otherwise in respect thereof or
related thereto, shall be obtainable by the Partnership or any Partner against
any direct or indirect member, partner, shareholder, incorporator, employee or
Affiliate, past, present or future, of any Limited Partner.

their capacity as such, if such Person shall also be a Limited Partner) shall
take part in the operation, management or control of the Partnership’s name or
have the power to sign documents for or otherwise bind the Partnership.  The transaction of any business by a General
Partner or any director, manager, partner, officer, employee or agent of a
General Partner in its capacity as such shall not affect, impair or eliminate the
limitations on the liability of any Limited Partner under this Agreement.

Section 10.3.  
Outside Activities. 
(i) The TCV Group, the Blackstone Group, the OEP Group, any partner,
member, officer, director, employee or Affiliate of the foregoing may engage in
or possess any interest in other investments, business ventures or Persons of
any nature or description, independently or with others, similar or dissimilar
to, or that competes with, the investments or business of the Partnership and
its Subsidiaries, and may provide advice and other assistance to any such
investment, business venture or Person, (ii) the Partnership and the Partners
shall have no rights by virtue of this Agreement in and to such investments,
business ventures or Persons or the income or profits derived therefrom, and
(iii) the pursuit of any such investment or venture, even if competitive with

wrongful or improper.  None of the TCV
Group, the

 30
 

Blackstone Group, the OEP Group, any partner,
member, officer, director, employee or Affiliate of the foregoing shall be
obligated to present any particular investment or business opportunity to the
Partnership even if such opportunity is of a character that, if presented to

Blackstone Group, the OEP Group, and any partner, member, officer, director,
employee or Affiliate of the foregoing shall have the right to pursue for its
own account (individually or as a partner or a fiduciary) or to recommend to
any other Person any such investment opportunity.  Nothing in this Section 10.3 as it relates to
any partner, member, officer, director or employee of any such Person shall
limit the obligations of such partner, member, officer, director or employee of
any such Person under any other agreements (including any employment
agreements) with the Partnership or its Subsidiaries or under any policy of the
Partnership or its Subsidiaries to which such partner, member, officer,
director or employee may be subject from time to time.

ARTICLE XI

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.

 31

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

 32
 

taxes, penalties,
additions to tax or interest) with respect to income attributable to or
distributions or other payments to such Partner.

ARTICLE XII

MANAGEMENT LIMITED PARTNERS

Section 12.1.  
Vested Interests and Unvested Interests; Forfeiture of Unvested Interests.

(a)                                  Management
Interests shall be held subject to the terms and conditions of a Management
Equity Award Agreement which will include vesting conditions applicable to such
Interests.

(b)                                 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 Cause (as defined in the applicable Management Equity Award Agreement), all
outstanding Management Interests held by such Management Limited Partner
(including both Unvested Interests and Vested Interests) shall be forfeited
without consideration.

(c)                                  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 other as described in clause (b) above (including death or
Disability (as defined in the applicable Management Equity Award Agreement)),
all outstanding Management Interests held by such Management Limited Partner
that are Unvested Interests shall be forfeited without consideration.

Section 12.2.  
Call 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
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

 33
 

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 60th  day
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 (as defined in the applicable
Management Equity Award Agreement), the purchase price for the Management
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).

(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”)).

 34
 

(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

 35
 

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 181st 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

 36
 

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 of
such Management Interests implied by an enterprise value for the Partnership as
determined in good faith by the General Partner in

 37
 

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

 38
 

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

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

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

 39
 

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.

 40
 

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.

 41
 

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

 42
 

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,
