the Option Agreement. In the event the Company issues Membership Units pursuant to the Option Agreement, the rights, powers, preferences and relative participating, optional or other special rights of
such Membership Units shall be set forth in a separate schedule to this Agreement or incorporated into the terms of the Preferred Membership Units set forth on  Schedule C hereto. 

        3.2.    Unit Option Plan.    The Members acknowledge that, in connection with the execution of this Agreement, the
Board will adopt an option, Membership Unit purchase or similar plan or arrangement for the benefit of employees, consultants or members of the Board of the Company or its Subsidiaries (the
"Option Plan"). The Option Plan will provide for not less than 12,549,655 Common Membership Units to be available for issuance, subject to increase from
time to time by action of the Board. In connection with, and subject to the terms of, the Option Plan, the Board is empowered to cause the Company to sell or grant from time to time to Members or any
other Persons, including, without limitation, employees and members of the Board, Common Membership Units in the Company in such amounts, with such
terms and conditions and in such manner (including, without limitation, restricted Common Membership Unit grants or other option or incentive programs)
(collectively, the "Option Units") as permitted by the Option Plan in exchange for cash, services performed or to be performed for or on behalf of the
Company, or any of its Affiliates, in-kind contributions of property to the Company or such other consideration as may be deemed advisable by the Board from time to time, and to admit the
holders thereof as additional Members, all upon such terms and subject
to such conditions as may be determined by the Board from time to time and as permitted by the Option Plan. On or prior to the admission of any additional Member hereunder, the additional Member
shall, as a condition to the issuance of Option Units to such Member, execute and deliver to the Company a Joinder Agreement to this Agreement, substantially in the form of  Exhibit A hereto (the
"Joinder Agreement"). Upon such execution and delivery,  Schedule B hereto shall be deemed to be amended to include the name of such additional Member

contributed to capital of the Company the property or amount set forth opposite such Member's name on the attached Schedule A or  Schedule B, as
applicable. Each Member's number of Preferred Membership Units or Common Membership Units, or any combination of the foregoing, is
set forth opposite such Member's name on Schedule A or Schedule B, as applicable, which

8

 

amended
from time to time upon admission of new Members or the acceptance of additional Capital Contributions as set forth herein or the issuance of new Membership Units by the Company. Each Member
acknowledges that, for purposes of establishing the initial Capital Account balances of the Members, the total amount of cash and agreed Fair Market Value of any property contributed by each Member
(net of any liabilities assumed by the Company and any liabilities to which such property is subject) is as set forth on Schedule A or  Schedule B,
 as applicable, to such Member, under the heading "Capital Contribution." 

        4.2.    Admission of New Members.    

        (a)    Admission of Common Members.    Additional Persons, including Persons who are officers or employees of, or
consultants to, the Company and/or any of its Affiliates, or have otherwise provided valuable services or opportunities to the Company or its Affiliates,  including, without
limitation, introducing investors to the Company, may be admitted to the Company as
Members from time to time as determined by the Board in its sole discretion. 

        (b)    Ownership of Membership Units.    In the event a Member ceases to own beneficially Membership Units, such
Member shall no longer be deemed a Member for any purpose hereunder; provided, however, such Member shall continue to be bound by provisions that
survive pursuant to this Agreement, including, without limitation,  Section 6.3 herein. No less
frequently than as of the beginning of each Fiscal Year, the Company will prepare a new  Schedule A and Schedule B setting forth each Member's
Membership Units for such Fiscal
Year. 

        4.3.    Additional Contributions.    No Member will be required to make any contribution to the Company's capital in
addition to the amounts contributed or deemed contributed pursuant to Section 4.1 above. Subject to the foregoing, the Board may determine from
time to time that additional capital is necessary or appropriate to enable the Company to conduct its activities and seek (but not require) additional Capital Contributions from Members and others, on
such terms as the Board may propose in its sole discretion. 

        4.4.    Procedures for Admitting Additional Members.    Without limiting the terms contained elsewhere in this
Agreement, including, without limitation,  Section 3.2, Section 6.2 and  Article IX, as a condition to becoming a Member of the Company, all additional Members shall execute and deliver to the Company such
instruments,
in form and substance satisfactory to the Board as it may deem necessary or desirable to effectuate such admission, as the Board may require, evidencing such Member's intent to be bound by all of the
terms, covenants and conditions of this Agreement. The initial Capital Contribution of any additional Member shall be paid in cash or cash equivalents at the time of such Member's admission into the
Company, or in consideration otherwise acceptable to the Board in its sole discretion. Schedule A and  Schedule B will be amended, as necessary,
to reflect each additional Member admitted to the Company. 

        4.5.    Loans by Members.    No Member will be required to make loans to the Company by virtue of being a Member in
the Company.

        (a)    General.    The Board shall cause to be performed all general and administrative services on behalf of the
Company in order to assure that complete and accurate books and records of the Company are maintained at the Company's principal place of business showing the names, addresses and number of Membership
Units of each of the Members, all receipts and expenditures, assets and liabilities, profits and losses, and all other records necessary for recording 

9

 

the
Company's business and affairs, including a Capital Account for each Member. The Capital Accounts shall be maintained for each Member in accordance with Regulations §§
1.704-1(b) and 1.704-2. 

        (b)    Initial Capital Accounts.    As of the date of this Agreement,  Schedule A and Schedule B set forth the initial Capital Account balance of each Member
with respect to each class of Membership Unit held by such Member. 

        (c)    Adjustments to Capital Accounts.    The Capital Account with respect to the relevant Membership Units shall be
increased by: 

          (i)  the
amount of any money contributed by the Member to the Company; 

         (ii)  the
fair market value of any property contributed by the Member to the Company; 

        (iii)  the
amount of Net Profit allocated to the Member; and 

        (iv)  the
amount of any Company liabilities assumed by such Member (or taken subject to) if property is distributed to the Member by the Company; 

and
shall be decreased by: 

         (v)  the
amount of any money distributed to the Member by the Company; 

        (vi)  the
fair market value of any property distributed to the Member by the Company; 

       (vii)  the
amount of Net Loss allocated to the Member; and 

      (viii)  the
amount of any Member liabilities assumed by the Company (or taken subject to) if property is contributed to the Company by the Member. 

        (d)    Regulations § 1.704-1(b)(2)(iv).    The Capital Accounts shall be adjusted by all other
adjustments required by Regulations § l.704-l(b)(2)(iv). The foregoing provisions and the other provisions of this Agreement relating to the maintenance of Capital Accounts are
intended to comply with Regulations under § 704(b) of the Code and, to the extent not inconsistent with the provisions of this Agreement, shall be interpreted and applied in a manner
consistent with such Regulations. 

        (e)    Transfers.    If any Membership Units (or portions thereof) in the Company are transferred in accordance with
the terms of this Agreement, the Transferee will succeed to the Capital Account of the Transferor to the extent it relates to the Transferred Membership Units (or portions thereof). 

        5.2.    Allocations of Net Profit and Net Loss.    

        (a)   Subject
to Section 5.2(b), Net Profit and Net Loss shall be allocated among the Members so as to reduce,
proportionately, the difference between their respective Target Capital Accounts and Partially Adjusted Capital Accounts as of the end of such period, provided that no portion of Net Profit or Net
Loss for any period shall be allocated to a Member, in the case of a Net Profit, whose Partially Adjusted Capital Account is greater than or equal to its Target Capital Account or, in the case of a
Net Loss, whose Target Capital Account is greater than or equal to its Partially Adjusted Capital Account for such period. 

        (b)   If
(i) the Company has a Net Profit for any period and, notwithstanding the application of Section 5.2(a),
the balance of any Member's Partially Adjusted Capital Account is greater than the balance of its Target Capital Account, then the Member with such excess balance shall be specially allocated items of
Company expense or loss for such period (to the extent available) equal to the difference between its Partially Adjusted Capital Account and its Target Capital Account; (ii) the Company has a
Net Loss for any Period and, notwithstanding the application of 

10

 

 Section 5.2(a), the balance of any Member's Partially Adjusted Capital Account is less than the balance of its Target Capital Account, then the Member with such
deficient balance shall be specially allocated items of Company income or gain for such period (to the extent available) equal to the difference between its Partially Adjusted Capital Account and its
Target Capital Account; and (iii) the Company has neither a Net Profit nor a Net Loss for any period and, notwithstanding the application of  Section 5.2(a), the balance of any Member's
Partially Adjusted Capital Account differs from the balance of its Target Capital Account, then the
Member with an excess or deficient balance, as the case may be, shall be specially allocated items of Company expense or loss or income or gain, as the case may be, for such period (to the extent
available) equal to the difference between its Partially Adjusted Capital Account and its Target Capital Account. Solely for purposes of this  Section 5.2(b), Net Profit and Net Loss shall be
determined by giving effect to any items of gain, income, deduction or loss specially allocated
pursuant to this Section 5.2(b). 

        (c)    Change in Member's Membership Units.    If there is a change in any Member's share of the Company's Net Profit,
Net Loss or other items during any year, allocations among the Members shall be made in accordance with their interests in the Company from time to time during such year in accordance with
§ 706 of the Code, using the closing-of-the-books method. 

        (d)    Tax Allocations.    Except as otherwise provided herein, the income, gains, losses, credits and deductions
recognized by the Company shall be allocated among the Members, for United States federal, state and local income tax purposes, to the extent permitted under the Code and the Treasury Regulations, in
the same manner that each such item is allocated to the Members' Capital Accounts. 

        5.3.    Distributions Generally.    

        (a)    In General.    Except as provided in Section 10.2
(distributions upon liquidation) and this Section 5.3, the Company will make no distributions other than distributions described on  Schedule C
with respect to the Preferred Membership Units. Any cash (net of reasonable reserves) not otherwise distributable to the Preferred
Members pursuant to Schedule C shall be distributed at the discretion of the Board to the Common Members in proportion to their relative Common
Membership Units. 

        (b)    Tax Distributions.    Notwithstanding the provisions of  Section 5.3(a) above, if the Company has net taxable income for
federal income tax purposes for any taxable year, then the Company shall first
distribute at least an amount of any available cash (net of reasonable reserves) to each Member which, when combined with all other distributions to such Member in the current and all preceding
taxable years, equals the product of the highest combined federal, state and local marginal income tax rate applicable to any Member and the excess, if any, of (i) the aggregate net taxable
income allocated to such Member in the current and all preceding taxable years over (ii) the aggregate net taxable loss allocated to such Member in all preceding taxable years. Any amounts
distributed to a Member pursuant to this Section 5.3(b) shall reduce on a dollar for dollar basis until fully recovered any distribution to which
a Member is otherwise entitled under Section 5.3(a) above. 

        (c)    Distributions in Kind.    If any assets of the Company are distributed in kind, such assets will be distributed
in accordance with this Section 5.3 and on the basis of the Fair Market Value thereof at the effective time of the distribution, as reasonably
determined by the Board; provided that if all or any portion of any payment is made in property consisting of securities, the Board will give
instructions to Transfer such securities to the transfer agent for such securities on or before the due date of such payment, and such securities will be valued at Fair Market Value as of the date on
which the Board issues such instructions.

ARTICLE VI.    
    
    MEMBERS    
    

        6.1.    Limited Liability.    Except as may be required under the Act, no Member will be personally liable to any
third party for any debt, obligation or other liability of the Company, whether that liability or obligation arises in contract, tort or otherwise.    The failure of the Company to observe
any formalities or requirements relating to the exercise of its powers or management of its business or affairs under this Agreement or the Act will not be grounds for imposing personal liability on
the Members for liabilities of the Company. 

        6.2.    Admission of Additional Members.    Additional Members may be admitted only according to the provisions of
this Agreement, including, without limitation,  Article III and Article IX. 

        6.3.    Confidentiality.    

        (a)    Nondisclosure or Use of Confidential Information.    Except as may be required by law
(including, without limitation, the Securities Act, the Exchange Act and applicable rules and
regulations of the Securities and Exchange Commission) and as permitted by Section 6.3(b) below, each Member shall, at all times during the period in which it is a Member and after the complete
termination of its interest in the Company as a Member for any reason (including the dissolution and termination of the Company) (such period is hereinafter referred to as the
"Restricted Period"), treat as confidential, in the same manner and with the same degree of care as such Member treats its own confidential information,
any information not in the public domain or generally known in the industry, in any form, acquired by the Member in its capacity as a Member, relating to the Company, its Subsidiaries or their
respective businesses, including, but not limited to, information regarding customers, vendors, suppliers, trade secrets, technical information,
contracts, systems, procedures, know-how, trade names, improvements, price lists, financial or other data (including the revenues, costs or profits associated with any of the Company's
operations or services), business plans and financial statements, computer programs, software systems, databases, discs and printouts, plans (business, technical or otherwise), customer lists, which
is or was used in the business of the Company and/or its Subsidiaries. Each Member agrees and acknowledges that all of such confidential information, in any form, and copies and extracts thereof, are
and shall remain the sole and exclusive property of the Company. 

        (b)    Tax Disclosure.    Notwithstanding any statement to the contrary in this Agreement, or any other document
furnished to the Members concerning the Company, the Company, its Affiliates and its advisors authorize each Member and each Member's employees, representatives or other agents, to disclose to any and
all Persons without limitation of any kind the tax treatment and tax structure of the Company and all materials of any kind (including opinions or other tax analyses) relating to such tax treatment or
tax structure that are provided to each Member, except for any information identifying the Company, its Affiliates or other Members. For purposes hereof, the terms "tax treatment" and "tax structure"
shall have the meaning provided by Treasury Regulation Section 1.6011-4. 

        (c)    Injunctive Relief.    Without intending to limit the remedies available to the Company, each Member
acknowledges that a breach of any of the covenants contained in Section 6.3(a) hereof may result in material irreparable injury to the Company
for which there is no adequate remedy at law, that it will not be possible to measure damages for such injuries precisely and that, in the event of such a breach or threat thereof, the Company shall
be entitled to obtain a temporary restraining order and/or a preliminary or permanent injunction, without the necessity of proving irreparable harm or injury as a result of such breach or threatened
breach of Section 6.3(a) hereof, restraining the Member from engaging in activities prohibited by  Section 6.3(a) hereof or 

12

 

such
other relief as may be required specifically to enforce any of the covenants in Section 6.3(a) hereof. 

        6.4.    Other Business Ventures.    Any member of the Board (other than Officers (as defined herein) who are also
members of the Board) may engage in or possess an interest in other business ventures of every nature and description, independently or with others, whether or not similar to or in competition with
the business of the Company, and neither the Company, the Members nor any member of the Board shall have any right by virtue of this Agreement in or to such other business ventures or to the income or
profits derived therefrom. Unless otherwise agreed to, no member of the Board (other than Officers (as defined herein) who are also members of the Board) shall be required to devote all of such Board
member's time or business efforts to the affairs of the Company, but shall devote so much of such Board member's time and attention to the Company as is reasonably necessary and advisable to manage
the affairs of the Company to the best advantage of the Company. 

 
 

ARTICLE VII.

        (a)    Powers of the Board.    The management of the Company shall be vested in the Board. The Board shall be
comprised in accordance with the terms of the Preferred Membership Units (as set forth on Schedule C hereto) and, so long as it remains in
effect, with Section 2 of the Holders Agreement. Except as otherwise provided in this Agreement, the Board shall have all authority, rights and
powers in the management of the Company's business to do any and all acts and things necessary, appropriate, proper, advisable, incidental to or convenient for effectuating the purposes of this
Agreement. Any action taken by the Board on behalf of the Company in accordance with the provisions of this Agreement, including this  Article VII, shall constitute the act of and shall serve to
bind the Company. 

        (b)    Calling Meetings.    Any of (i) the Preferred Directors, (ii) the Chairman of the Board or
(iii) a majority of the Board shall have the authority in their sole discretion to call meetings of the Board. 

        (c)    Quorum; Voting Requirement; Adjournment.    A majority of the Board at any time in office shall constitute a
quorum. At any meeting at which a quorum is present, the vote of a majority of the members of the Board present shall be the act of the Board. The members of the Board shall act only as the Board and
the individual members thereof shall not have any powers as such. If a quorum shall not be present at any meeting of the Board, the Board members present thereat may adjourn the meeting to another
time and place. Notice of such time and place of the adjourned meeting shall be given to all of the Board members unless such time and place were announced at the meeting at which the adjournment was
taken, in which case such notice shall only be given to the Board members who
were not present thereat. At such adjourned meeting at which a quorum is present, any business may be transacted which might have been transacted at the meeting as originally called. 

        (d)    Action Without Meeting.    Any action required or permitted to be taken by the Board may be taken without a
meeting, without prior notice and without a vote if a consent in writing setting forth the action so taken is signed by not less than a majority of the Board (unless the action requires the consent of
more than a majority of the Board, in which case, such written consent shall be signed by the required members of the Board). Prompt notice of the taking of any action pursuant to this  Section 7.1(d) by less than unanimous written consent of the Board shall be given to those Board members who have not consented in writing. 

13

 

        (e)    Telephonic Meetings.    One or more Board members may participate in any meeting of the Board by means of
conference telephone or similar communications equipment by means of which all persons participating in the meeting can hear each other, and such participation in the meeting pursuant to this  Section 7.1(e)
 shall constitute presence in person at the meeting. 

        (f)    Authority of the Board.    The execution and delivery of any contract, agreement or instrument, or the taking
of any action, by the Board for the apparent purpose of carrying on the usual business or affairs of the Company, will bind the Company, and no Person dealing with the Company will have any obligation
to inquire into the power or authority of the Board apparently acting on behalf of the Company. However, in any case where this Agreement expressly calls for the written consent of the Board, the
Preferred Directors and/or the holders of the Preferred Membership Units, such consent will be valid only if actually executed by the Board, including the Preferred Directors and the required holders
of the Preferred Membership Units. 

        7.2.    Voting.    Notwithstanding the preceding provision of this  Article VII or any other provision of this Agreement to the
contrary, neither the Company nor any of its Subsidiaries shall, without first
obtaining the affirmative vote or written consent of a majority of the Preferred Directors:

        7.4.    Conversion to Corporate Form; Public Offering.    

        (a)   The
parties hereto acknowledge that the Board may approve a restructuring of the legal status and capital structure of the Company in the future in order to facilitate a
public offering of securities by a corporate entity that, immediately after such restructuring, shall own, directly or indirectly, 100% of the property and business of the Company and its Subsidiaries
(the "IPO Entity"), that such restructuring will result in the direct or indirect conversion of the Membership Units of the Company into capital stock
of the IPO Entity and that the decision to convert to corporate form and the form of such restructuring shall be at the sole discretion of the Board, with the Members having no vote or veto power with
respect to any such conversion. 

        (b)   Subject
to the foregoing, the Board may, without the consent of the Members, in order to facilitate a public offering of securities of the IPO Entity, cause the Company
to incorporate its business or any portion thereof, or require the holders of Membership Units to transfer such Membership Units or shares to a newly-formed corporation as successor to the Company in
exchange for common stock of
said corporation, including, without limitation, in a transaction resulting in a dissolution of the Company pursuant to  Article X of this Agreement,
and, in connection therewith, each Member hereby expressly agrees to any such dissolution of the Company and the
transfer of its Membership Units in accordance with the terms of the exchange as provided by the Board. 

        (c)   The
Members hereby acknowledge and agree that it is the intention of the Members that each member shall receive common stock in the IPO Entity of equivalent economic
value to the Membership Units exchanged therefor immediately prior to any restructuring under this Section 7.4, and that such exchange shall be
contingent upon consummation of a public offering of securities by the IPO Entity.

Registration Rights Agreement substantially in the form attached hereto as Exhibit B.

        7.5.    Members To Have No Managerial Authority; Certain Consents.    

        (a)    Non-Managing Members.    Except as expressly set forth in this Agreement, as set forth in the terms
of applicable employment agreements between the Company and any Member or as otherwise delegated to a Member by the Board, or as required by the Certificate or applicable law (including the Act), the
Non-Managing Members will have no power to participate in the management of the Company. Unless expressly and duly authorized in writing to do so by the Board, no Non-Managing
Member will have any power or authority to bind or act on behalf of the Company in any way, to pledge its credit, or to render it liable for any purpose. 

        (b)    Voting Rights.    In any case in which the holders of Membership Units shall be entitled to vote pursuant to
applicable law or pursuant to the terms of the Preferred Membership Units, each holder of a (i) Common Membership Unit shall be entitled to one vote for each Membership Unit held and
(ii) a Preferred Membership Unit shall be entitled to a number of votes equal to the number of Common Membership Units into which each such Preferred Membership Unit is convertible, as set
forth on, and pursuant to, Schedule C hereto. Required votes or consents of the Members may be given in Person or by proxy, either in writing or
by resolution adopted at an annual or special meeting called for such purposes. 

        7.6.    Meetings; Approvals.    Meetings of the Board shall be held in accordance with  Section 7.1 and meetings of the Members
shall be held at such times and on such dates as the Board shall determine. Notice of each such meeting
shall he provided by the Board to the Members at least two days prior to the date of such meeting. Any action required or permitted to be taken at any meeting of Members of the Company may be taken

17

 

writing
setting forth the action so taken is signed by the Members holding not less than the minimum number of Membership Units that would be necessary to authorize or take such action at a meeting of
the Members. Prompt notice of the taking of any action taken pursuant to this Section 7.6 by less than the unanimous written consent of the
Members shall be given to those Members who have not consented in writing. For purposes of obtaining any consent of the Members or any class of Members (or a specified percentage in interest thereof)
as to any matter proposed by the Board, the Board may, in the notice seeking such consent, require a response within a specified period (which shall not be less than ten days). In addition to meetings
called by the Board as set forth above in this Section 7.6, the Board may, with or without formal notice, hold informal informational meetings of
the Board and one or more Members in any manner consistent with the Act at such times and on such dates as the Board may in its sole discretion determine. 

        7.7.    Liability and Indemnification of the Board.    

        (a)    Indemnification.    The Company shall indemnify to the fullest extent permitted under and in accordance with
the laws of the State of Delaware any person 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 (other than an action by or in the right of the Company) by reason of the fact that the person is or was a member of the Board, Officer, employee or agent of the
Company, or is or was serving at the request of the Company as a member of the Board, officer, employee or agent of another corporation, or of a partnership, joint venture, trust or other enterprise,
against expenses (including attorneys' fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by the person in connection with such action, suit or proceeding if the
person acted in good faith and in a manner the person reasonably believed to be in or not opposed to the best interests of the Company, and, with respect to any criminal action or proceeding, had no
reasonable cause to believe the person's conduct was unlawful. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nolo contendere or its
equivalent, shall not, of itself, create a presumption that the person did not act in good faith and in a manner which the person reasonably believed to be in or not opposed to the best interests of
the Company, and, with respect to any criminal action or proceeding, had reasonable cause to believe that the person's conduct was unlawful. 

        (b)    Additional Indemnification.    The Company shall indemnify any person who was or is a party or is threatened to
be made a party to any threatened, pending or completed action or suit by or in the right of the Company to procure a judgment in its favor by reason of the fact that the person is or was a member of
the Board, Officer, employee or agent of the Company, or is or was serving at the request of the Company as a member of the Board, officer, employee or agent of another corporation, or of a
partnership, joint venture, trust or other enterprise against expenses (including attorneys' fees) actually
and reasonably incurred by the person in connection with the defense or settlement of such action or suit if the person acted in good faith and in a manner the person reasonably believed to be in or
not opposed to the best interests of the Company and except that no indemnification shall be made in respect of any claim, issue or matter as to which such person shall have been adjudged to be liable
to the Company unless and only to the extent that the Court of Chancery or the court in which such action or suit was brought shall determine upon application that, despite the adjudication of
liability but in view of all the circumstances of the case, such person is fairly and reasonably entitled to indemnity for such expenses which the Court of Chancery or such other court shall deem
proper. 

        (c)    Advance of Expenses.    Expenses incurred in defending a civil or criminal action, suit or proceeding shall (in
the case of any action, suit or proceeding against a member of the Board) or may (in the case of any action, suit or proceeding against an Officer, trustee, employee or agent) be paid by the Company
in advance of the final disposition of such action, suit or proceeding as 

18

 

authorized
by the Board upon receipt of an undertaking by or on behalf of the indemnified person to repay such amount if it shall ultimately be determined that he is not entitled to be indemnified
under this Article. 

        (d)    Rights Not-Exclusive.    The indemnification and other rights set forth in this  Section 7.7 shall not be exclusive of
any provisions with respect thereto in any other contract or agreement between the Company and any Officer,
member of the Board, employee or agent of the Company. 

        (e)    Reliance on Agents.    The Board may execute any power granted by, or perform any duty imposed by, this
Agreement either directly or through agents, including any of its Affiliates. The Board may consult with counsel, accountants, appraisers, management consultants, investment bankers and other
consultants. An opinion by any such Person on a matter that the Board believes to be within such Person's professional or expert competence will be full and complete protection for any action taken or
omitted by the Board in good faith based on the opinion. The Board will not be responsible for the misconduct, negligence, acts, or omissions of any such Person or of any agent or employee of the
Company, the Board, or any of their Affiliates. 

        7.8.    Special Tax Covenants.    

        (a)    UBTI.    The Company shall conduct the affairs of the Company in a manner that does not cause any of the
Warburg Investors or any direct or indirect partner or member thereof, that is exempt from income taxation pursuant to Section 501 of the Code, to have any "unrelated business taxable income"
("UBTI"), including, without limitation, any "unrelated debt-financed income" (as those
terms are defined in Sections 512 and 514 of the Code), or gross income attributable to a "trade or business" (within the meaning of Sections 512 and 513 of the Code) and the Company shall not take
any action that will cause any such Person to have any UBTI or gross income attributable to a "trade or business." If at any time the Company becomes aware that it is reasonably likely that any such
Person has incurred or will incur UBTI or gross income attributable to a "trade or business" as a result of such Person's direct or indirect interest in the Company, the Company shall promptly notify
such Person of such fact in writing. If as a result of the incurrence of UBTI or gross income attributable to a "trade or business" relating to an investment or activity of the Company, the Company
becomes obligated to provide notice to a Person pursuant to the preceding sentence, the Company shall promptly thereafter take whatever action may be reasonably necessary to preclude any further
realization of UBTI or gross income attributable to a "trade or business" from such investment or activity. Without limiting the generality of the foregoing, the Company shall not invest in any entity
that is (or would be after such investment) classified as a partnership or other pass through vehicle for federal income tax purposes, or incur indebtedness in connection with the acquisition of any
Investment. 

        (b)    ECI.    The Company shall conduct the affairs of the Company so that the Warburg Investors shall be not be
deemed engaged in a "trade or business" for federal income tax purposes, including for purposes of Section 871, 872(a), 875, 882 or 884(d) of the Code, by virtue of the activities or
investments of the Company. If at any time the Company becomes aware that it is reasonably likely that any of the Warburg Investors shall be deemed engaged in a trade or business by virtue of the
activities or investments of the Company, the Company shall promptly notify the Warburg Investors in writing, and shall promptly thereafter take whatever action consistent with the intended scope of
its business may be reasonably necessary to ensure that no Warburg Investor shall be deemed engaged in a "trade or business" for purposes of Section 871, 872(a), 875, 882 or 884(d) of the Code
by virtue of the activities or investments of the Company.

        (g)   The
Company's books and records for at least the current and most recent six fiscal years, if applicable. 

        8.3.    Inspection of Records.    Each Member has the right, on reasonable request, but subject to such Member's
agreement to maintain the confidentiality thereof, to: 

        (a)   Inspect
and copy (at such Member's expense) during normal business hours any of the Company records required to be maintained by  Section 8.1; and 

        (b)   Obtain
from the Company, promptly after they are available, a copy of the Company's federal, state, and local income tax or information returns for each year. 

        Each
Member acknowledges that the provisions of this Article VIII, including, without limitation, this  Section 8.3, are reasonable standards for the
rights to inspect and copy records of the Company. 

        8.4.    Tax Returns and Elections.    The Company's tax or Fiscal Year will end on December 31st
of each year unless otherwise determined by the Board. The Company's accountants will be instructed to prepare and file all required income tax returns for the Company. The Board will make any tax
election necessary for completion of the Company's tax returns. If a distribution of property is made in the manner provided in § 734 of the Code, or if a Transfer of any Membership Unit

§ 754 of the Code in accordance with the procedures set forth in the applicable Regulations promulgated thereunder. 

        8.5.    Tax Matters Partner.    Warburg, Pincus Equity Partners will be the "tax matters partner" as defined in
§ 6231 of the Code, and will have all the authority granted by the Code to the tax matters partner, including the authority, without the consent of any other Member, to do all of
the following: 

20

 

(i) enter
into a settlement agreement with the Internal Revenue Service (and any state taxing authority) that purports to bind the other Members; (ii) file a petition as
contemplated in § 6226(a) or § 6228 of the Code; (iii) intervene in any action as contemplated in § 6226(b)(5) of the Code; (iv) file any request

exclusive authority to negotiate and enter into settlement agreements on such Member's behalf with the Internal Revenue Service (and any state taxing authorities) in connection with any tax audit
proceeding and waives any right to negotiate or enter into such settlement agreements. Each Member hereby waives any and all defenses that may be available to contest, negate or disaffirm the action
of the tax matters partner taken in good faith pursuant hereto. Warburg, Pincus Equity Partners may from time to time appoint any other Member to be the tax matters partner on behalf of the Company. 

        8.6.    Withholding and Tax Advances.    

        (a)    Authority To Withhold.    To the extent the Company is required by law to withhold or to make tax payments on
behalf of or with respect to any Member (e.g., (i) backup withholding, (ii) withholding with respect to Members that are neither citizens nor residents of the United States, or
(iii) withholding with respect to Members that are not residents of any state that the Company is required to withhold from) (collectively, "Tax
Advances"), the Company may withhold such amounts and make such tax payments as may be required. 

        (b)    Repayment of Tax Advances.    All Tax Advances made on behalf of a Member will, at the option of the Company,
either be (i) promptly paid to the Company by the Member on whose behalf such Tax Advances were made, or (ii) repaid by reducing the amount of the current or next succeeding distribution
or distributions which would otherwise have been made to such Member (or, if such distributions are not sufficient for that purpose, by so reducing the proceeds of liquidation otherwise payable to
such Member). Whenever the Company selects option (ii) pursuant to the preceding sentence for repayment of a Tax Advance by a Member, for all other purposes of this Agreement such Member will
be treated as having received all distributions (whether before or upon liquidation) unreduced by the amount of such Tax Advance. 

        (c)    Indemnification.    Each Member hereby agrees to indemnify and hold harmless the Company from and against any
liability with respect to Tax Advances made on behalf of or with respect to such Member. 

        (d)    Certification.    Each Member will promptly give the Company any certification or affidavit that the Company
may request in connection with this Section 8.6. 

        8.7.    Bank and Brokerage Accounts.    The Board will maintain the funds of the Company in one or more separate

to any restrictions set forth in the Holders Agreement, as amended from time to time. 

        9.2.    Allocations between Transferor and Transferee.    In the case of any Transfer, the Transferee will succeed to
the Capital Account of the Transferor with respect to the Transferred Membership Units. The Net Profit and Net Loss allocable in respect of the Transferred Membership Units will be prorated between
the Transferor and the Transferee on the basis of the number of days in the Fiscal Year that each was the holder of those Membership Units without regard to the performance of the Company's assets
during the period before and after the effective date of the Transfer, unless the Transferor and the Transferee agree to an allocation based on the performance of the Company's assets as of the
effective date of the Transfer (or any other method permissible under the Code) and agree to reimburse the Company for the cost of making and reporting any such allocation.

ARTICLE XIII.    
    
    MISCELLANEOUS PROVISIONS    
    

        13.1.    Appointment of an Attorney-in-Fact.    

        (a)   Each
Member, by the execution of this Agreement, irrevocably constitutes and consents to the appointment of a Person to be designated by the Board as its true and lawful
attorney-in-fact ("Attorney-in-Fact") with full power and authority in its name, place and stead to
execute, acknowledge, deliver, swear to, file, and record at the appropriate public offices such documents as a Member may be obligated to execute and deliver or as may be necessary or 

24

 

appropriate
to: (i) form, qualify, or continue the Company as a limited liability company in the jurisdiction in which the Company may conduct business or in which such formation, qualification
or continuation is, in the discretion of the Board, necessary to protect the limited liability of the Member; or (ii) all conveyances and other instruments which the Board deems appropriate to
reflect the dissolution and termination of the Company; and (iii) as to each Member, any and all documents necessary to convey such Member's Membership Units in the Company to any Transferee
thereof to the extent the Member has consented to such Transfer and to give effect to any withdrawal of such Member from the Company as a result of such Transfer and admit any substitute Member to the
Company. 

        (b)   The
appointment by all Members of the Attorney-in-Fact will be deemed to create a power coupled with an interest, in recognition of the fact that
the Members under this Agreement will be relying upon the power of the Attorney-in-Fact to act as contemplated by this Agreement in any filing and other action by it on behalf
of the Company, and will survive any event of bankruptcy, death, adjudication of incompetence or dissolution of any Person giving such power, and the Transfer of all or any part of the Membership
Units of such Person; provided, however, that in the event of a Transfer, the foregoing power of
attorney will survive such Transfer only until such time as the Transferee will have been admitted to the Company as a substituted Member and all required documents and instruments will have been duly
executed, filed and recorded to effect such substitution.
