UNITS, CAPITAL CONTRIBUTIONS AND ACCOUNTS 

Section 3.1 Units; Capitalization. 

(a) Units; Capitalization. The Company shall have the authority to issue an unlimited number of Common Units and Convertible Preferred
Units. Immediately following the IPO, the Company will issue Common Units to Maravai Co. in exchange for a contribution of the net proceeds received by Maravai Co. from the IPO (less any proceeds used to purchase Common Units from Holdings) to the
Company, such that following the sale of Common Units by Holdings and the issuance of Common Units by the Company, the total number of Common Units held by Maravai Co. will equal the total number of outstanding shares of Class A Common Stock.
The ownership by a Member of Common Units shall entitle such Member to allocations of Profits and Losses and other items and Distributions of cash and other property as set forth in Article IV hereof. 

(b) Unit Ownership Ledger; Capital Contributions. The Manager shall create and maintain a ledger (the “Unit Ownership
Ledger”) setting forth the name and address of each Unitholder, the number of each class of Units held of record by each such Unitholder, and the amount of the Capital Contribution made with respect to each class of Units and the date of
such Capital Contribution. Upon any change in the number or ownership of outstanding Units (whether upon an issuance of Units, a Transfer of Units, a cancellation of Units or otherwise), the Manager shall amend and update the Unit Ownership Ledger.
Absent manifest error, the ownership interests recorded on the Unit Ownership Ledger shall be conclusive record of the Units that have been issued and are outstanding. Each Unitholder named in the Unit Ownership Ledger has made (or shall be deemed
to have made) Capital Contributions to the Company as set forth in the Unit Ownership Ledger in exchange for the Units specified in the Unit Ownership Ledger. Any reference in this Agreement to the Unit Ownership Ledger shall be deemed a reference
to the Unit Ownership Ledger as amended and in effect from time to time. 

  
 10 













 (c) Certificates; Legends. Units shall be issued in uncertificated form;
provided that, at the request of any Member, the Manager may cause the Company to issue one or more certificates to any such Member holding Units representing in the aggregate the Units held by such Member. If any certificate representing
Units is issued, then such certificate shall bear a legend substantially in the following form: 
 THIS CERTIFICATE EVIDENCES UNITS
REPRESENTING A MEMBERSHIP INTEREST IN MARAVAI TOPCO HOLDINGS, LLC. THE MEMBERSHIP INTEREST IN MARAVAI TOPCO HOLDINGS, LLC REPRESENTED BY THIS CERTIFICATE HAS NOT BEEN REGISTERED UNDER THE U.S. SECURITIES ACT OF 1933, AS AMENDED, OR ANY NON-U.S. OR STATE SECURITIES LAWS AND MAY NOT BE OFFERED, SOLD, PLEDGED OR OTHERWISE TRANSFERRED EXCEPT IN COMPLIANCE THEREWITH. THE MEMBERSHIP INTEREST IN MARAVAI TOPCO HOLDINGS, LLC REPRESENTED BY THIS CERTIFICATE
IS SUBJECT TO RESTRICTIONS ON TRANSFER SET FORTH IN THE SECOND AMENDED AND RESTATED LIMITED LIABILITY COMPANY AGREEMENT OF MARAVAI TOPCO HOLDINGS, LLC, DATED AS OF NOVEMBER 19, 2020, AS THE SAME MAY BE AMENDED FROM TIME TO TIME, A COPY OF WHICH
SHALL BE FURNISHED BY THE COMPANY TO THE RECORD HOLDER HEREOF UPON WRITTEN REQUEST AND WITHOUT CHARGE. 
 (d) Prior Common Units. The
Common Units that were issued and outstanding and held by the Members prior to the date of this Agreement shall remain unchanged. 

Section 3.2 Authorization and Issuance of Additional Units. 

(a) The Manager shall have the right to cause the Company to issue and/or create and issue at any time after the date hereof, and for such
amount and form of consideration as the Manager may determine, additional Units or other Equity Securities of the Company (including creating classes or series thereof having such powers, designations, preferences and rights as may be determined by
the Manager). The Manager shall have the power to make such amendments to this Agreement in order to provide for such powers, designations, preferences and rights as the Manager in its discretion deems necessary or appropriate to give effect to such
additional authorization or issuance in accordance with the provisions of this Section 3.2(a). In connection with any issuance of Units (whether on or after the date of this Agreement), the Person who acquires such Units
shall execute a counterpart to this Agreement accepting and agreeing to be bound by all terms and conditions hereof, and shall enter into such other documents, instruments and agreements to effect such purchase as are required by the Manager
(including such documents, instruments and agreements entered into on or prior to the date of this Agreement by the Members, each, an “Equity Agreement”). 

  
 11 













 (b) At any time Maravai Co. issues one or more shares of Class A Common Stock (other
than an issuance of the type covered by Section 3.2(d) or an issuance to a holder of Exchangeable Units pursuant to the Exchange Agreement, as described in Section 3.2(c)), Maravai Co. shall
contribute to the Company all of the net proceeds (if any) received by Maravai Co. with respect to such share or shares of Class A Common Stock. Upon the contribution by Maravai Co. to the Company of all of such net proceeds so received by
Maravai Co., the Manager shall cause the Company to issue a number of Common Units determined based upon the Exchange Rate then in effect, registered in the name of Maravai Co.; provided, however, that if Maravai Co. issues one or more shares
of Class A Common Stock, some or all of the net proceeds of which are to be used to fund expenses or other obligations of Maravai Co. for which Maravai Co. would be permitted a Distribution pursuant to Article IV, then Maravai Co. shall
not be required to transfer such net proceeds to the Company which are used or will be used to fund such expenses or obligations; provided further, if Maravai Co. issues any shares of Class A Common Stock in order to purchase or
fund the purchase of Common Units from a Member (other than a Subsidiary of Maravai Co.), then the Company shall not issue any new Common Units registered in the name of Maravai Co. in accordance with Section 3.2(c) and
Maravai Co. shall not be required to transfer such net proceeds to the Company (it being understood that such net proceeds shall instead be transferred by Maravai Co. to such other Member as consideration for such purchase). Notwithstanding the
foregoing, this Section 3.2(b) shall not apply to the issuance and distribution to holders of shares of Class A Common Stock of rights to purchase Equity Securities of Maravai Co. under a “poison pill” or
similar shareholder’s rights plan (it being understood that (i) upon exchange of Exchangeable Units for Class A Common Stock pursuant to the Exchange Agreement, such Class A Common Stock would be issued together with any such
corresponding right and (ii) in the event such rights to purchase Equity Securities of Maravai Co. are triggered, Maravai Co. will ensure that the holders of Common Units that have not been Exchanged prior to such time will be treated equitably
vis-à -vis the holders of Class A Common Stock under such plan). 

(c) At any time a holder of Exchangeable Units exchanges such Common Units for shares of Class A Common Stock or a Cash Payment, the
Company shall cancel such Exchangeable Units. Upon the cancellation by the Company of the Exchangeable Units exchanged for shares of Class A Common Stock, the Manager shall cause the Company to issue a number of Common Units equal to the
Exchanged Unit Amount, registered in the name of Maravai Co. in accordance with Section 2.6 of the Exchange Agreement. 
 (d) At any
time Maravai Co. issues one or more shares of Class A Common Stock in connection with an equity incentive program, whether such share or shares are issued upon exercise (including cashless exercise) of an option, settlement of a restricted
stock unit, as restricted stock or otherwise, the Manager shall cause the Company to issue a corresponding number of Common Units, registered in the name of Maravai Co. (determined based upon the Exchange Rate then in effect); provided that
Maravai Co. shall be required to contribute all (but not less than all) of the net proceeds (if any) received by Maravai Co. from or otherwise in connection with such issuance of one or more shares of Class A Common Stock, including the
exercise price of any option exercised, to the Company. If any such shares of Class A Common Stock so issued by Maravai Co. in connection with an equity incentive program are subject to vesting or forfeiture provisions, then the Common Units
that are issued by the Company to Maravai Co. in connection therewith in accordance with the preceding provisions of this Section 3.2(d) shall be subject to vesting or forfeiture on the same basis; if any of such shares of
Class A Common 

  
 12 













 
Stock vest or are forfeited, then a corresponding number of the Common Units (determined based upon the Exchange Rate then in effect) issued by the Company in accordance with the preceding
provisions of this Section 3.2(d) shall automatically vest or be forfeited. Any cash or property held by Maravai Co. or the Company or on any of such Person’s behalf in respect of dividends paid on restricted shares of
Class A Common Stock that fail to vest shall be returned to the Company upon the forfeiture of such restricted shares of Class A Common Stock. 

(e) Maravai Co. shall at all times reserve and keep available out of its authorized but unissued Class A Common Stock, solely for the
purpose of issuance upon an Exchange, the maximum number of shares of Class A Common Stock as shall be issuable upon Exchange of all outstanding Common Units and shares of Class B Common Stock to satisfy its obligations under the Exchange
Agreement; provided that nothing contained herein shall be construed to preclude Maravai Co. from satisfying its obligations in respect of any such Exchange by delivery of purchased shares of Class A Common Stock (which may or may not be
held in the treasury of Maravai Co.). If any shares of Class A Common Stock require registration with or approval of any Governmental Entity under any federal or state law before such shares may be issued upon an Exchange, Maravai Co. shall use
reasonable efforts to cause the exchange of such shares of Class A Common Stock to be duly registered or approved, as the case may be. Maravai Co. shall list and use its reasonable efforts to maintain the listing of the Class A Common
Stock required to be delivered upon any such Exchange prior to such delivery upon the national securities exchange upon which the outstanding shares of Class A Common Stock are listed at the time of such Exchange (it being understood that any
such shares may be subject to transfer restrictions under applicable securities laws). Maravai Co. covenants that all shares of Class A Common Stock issued upon an Exchange will, upon issuance, be validly issued, fully paid and non-assessable. 
 (f) For purposes of this Section 3.2, “net
proceeds” means gross proceeds to Maravai Co. from the issuance of Class A Common Stock or other securities less all reasonable bona fide
out-of-pocket fees and expenses of Maravai Co., the Company and their respective Subsidiaries actually incurred in connection with such issuance. 

(g) In the event Maravai Co. issues any Class A Common Stock upon conversion of any shares of Convertible Preferred Stock, a
corresponding number of Convertible Preferred Units shall be cancelled and cease to be outstanding, and the Company shall issue to Maravai Co. Common Units in accordance with Section 3.2(b) without any further action by the
Company or the Manager. 
 (h) In the event Maravai Co. makes a Distribution of cash in respect of the Convertible Preferred Units in
connection with any Convertible Preferred Stock Change of Control Repurchase or Convertible Preferred Stock Liquidation Payment, a number of Convertible Preferred Units shall be cancelled and cease to be outstanding equal to the number of shares of
Convertible Preferred Stock repurchased or liquidated, respectively, without any further action by the Company or the Manager. 
 (i) In the
event Maravai Co. repays (or otherwise retires) the principal of any outstanding Senior Notes, one Non-Convertible Preferred Unit shall be cancelled and cease to be outstanding for each $1,000 principal amount
of any Senior Notes that is repaid or otherwise retired without any further action by the Company or the Manager. 

  
 13 













 Section 3.3 Repurchase or Redemption of
Class A Common Stock. If, at any time, any shares of Class A Common Stock are repurchased or redeemed (whether by exercise of a put or call, automatically or by means of another arrangement) by Maravai
Co. for cash, then the Manager shall cause the Company, immediately prior to such repurchase or redemption of such shares, to redeem a corresponding number of Common Units held by Maravai Co. (determined based upon the Exchange Rate then in effect),
at an aggregate redemption price equal to the aggregate purchase or redemption price of the share or shares of Class A Common Stock being repurchased or redeemed by Maravai Co. (plus any reasonable expenses related thereto) and upon such other
terms as are the same for the share or shares of Class A Common Stock being repurchased or redeemed by Maravai Co. 

Section 3.4 Changes in Common Stock. In addition to any other adjustments required hereby, any
subdivision (by stock split, stock dividend, reclassification, recapitalization or otherwise) or combination (by reverse stock split, reclassification, recapitalization or otherwise) of Class A Common Stock, Class B Common Stock or other
capital stock of Maravai Co. shall be accompanied by an identical subdivision or combination, as applicable, of the Common Units or other Equity Securities, as applicable.

of Treasury Regulation Section 1.704-1(b)(2)(iv). For this purpose, the Company may (in the sole discretion of the Manager), upon the occurrence of the events specified in Treasury Regulation Section 1.704-1(b)(2)(iv)(f), increase or decrease the Capital Accounts in accordance with the rules of such regulation and Treasury Regulation
Section 1.704-1(b)(2)(iv)(g) to reflect a revaluation of the Company property. Without limiting the foregoing, each Unitholder’s Capital Account shall be adjusted: 

(i) by adding any additional Capital Contributions made by such Unitholder in consideration for the issuance of Units; 

(ii) by deducting any amounts paid to such Unitholder in connection with the redemption or other repurchase by the Company of
Units; 
 (iii) by adding any Profits allocated in favor of such Unitholder and subtracting any Losses allocated in favor of
such Unitholder; and 
 (iv) by deducting any distributions paid in cash or other assets to such Unitholder by the Company.

 (b) Computation of Income, Gain, Loss and Deduction Items. For purposes of computing the amount of any item of the Company income,
gain, loss or deduction to be allocated pursuant to Article IV and to be reflected in the Capital Accounts, the determination, recognition and classification of any such item shall be the same as its determination, recognition and
classification for federal income Tax purposes (including any method of depreciation, cost recovery or amortization used for this purpose); provided that: 

  
 14 













 (i) the computation of all items of income, gain, loss and deduction shall
include those items described in Code Section 705(a)(1)(B), Code Section 705(a)(2)(B) and Treasury Regulation Section 1.704-1(b)(2)(iv)(i), without regard to the fact that such items are not
includable in gross income or are not deductible for federal income Tax purposes; 
 (ii) if the Book Value of any Company
property is adjusted pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(e) or (f), the amount of such adjustment shall be taken into account as gain or loss from the disposition of such property;

 (iii) items of income, gain, loss or deduction attributable to the disposition of the Company property having a Book Value
that differs from its adjusted basis for Tax purposes shall be computed by reference to the Book Value of such property; 

(iv) items of depreciation, amortization and other cost recovery deductions with respect to the Company property having a Book
Value that differs from its adjusted basis for Tax purposes shall be computed by reference to the property’s Book Value in accordance with Treasury Regulation Section 1.704-1(b)(2)(iv)(g); 

(v) to the extent an adjustment to the adjusted Tax basis of any of the Company’s asset pursuant to Code Sections 732(d),
734(b) or 743(b) is required pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(m) to be taken into account in determining Capital Accounts, the amount of such adjustment to the Capital Accounts
shall be treated as an item of gain (if the adjustment increases the basis of the asset) or loss (if the adjustment decreases such basis); and 

(vi) this Section 3.5 shall be applied in a manner consistent with the principles of Prop. Reg.
Sections 1.704-1(b)(2)(iv)(d), (f)(1), (h)(2) and (s). 
 Section 3.6
Negative Capital Accounts; No Interest Regarding Positive Capital Accounts. No Unitholder shall be required to pay to any other Unitholder or the Company any deficit or negative balance which may exist from time to time in such
Unitholder’s Capital Account (including upon and after dissolution of the Company). Except as otherwise expressly provided herein, no Unitholder shall be entitled to receive interest from the Company in respect of any positive balance in its
Capital Account, and no Unitholder shall be liable to pay interest to the Company or any Unitholder in respect of any negative balance in its Capital Account. 

Section 3.7 No Withdrawal. No Person shall be entitled to withdraw any part of such Person’s
Capital Contributions or Capital Account or to receive any Distribution from the Company, except as expressly provided herein. 

Section 3.8 Loans From Unitholders. Loans by Unitholders to the Company shall not be considered
Capital Contributions. If any Unitholder shall loan funds to the Company in excess of the amounts required hereunder to be contributed by such Unitholder to the capital of the Company, the making of such loans shall not result in any increase in the
amount of the Capital Account of such Unitholder. The amount of any such loans shall be a debt of the Company to such Unitholder and shall be payable or collectible in accordance with the terms and conditions upon which such loans are made. 

  
 15 













 Section 3.9 Adjustments to Capital Accounts for
Distributions In-Kind. To the extent that the Company distributes property in-kind to the Members, the Company shall be treated as making a distribution equal to
the Fair Market Value of such property (as of the date of such distribution) for purposes of Section 4.1 and such property shall be treated as if it were sold for an amount equal to its Fair Market Value and any resulting
gain or loss shall be allocated to the Members’ Capital Accounts in accordance with Section 4.2 through Section 4.4. 

Section 3.10 Transfer of Capital Accounts. The original Capital Account established for each
Substituted Member shall be in the same amount as the Capital Account of the Member (or portion thereof) to which such Substituted Member succeeds at the time such Substituted Member is admitted to as a Member of the Company. The Capital Account of
any Member whose interest in the Company shall be increased or decreased by means of (a) the Transfer to it of all or part of the Units of another Member or (b) the repurchase or forfeiture of Units pursuant to any Equity Agreement shall
be appropriately adjusted to reflect such Transfer or repurchase. Any reference in this Agreement to a Capital Contribution of or Distribution to a Member that has succeeded any other Member shall include any Capital Contributions or Distributions
previously made by or to the former Member on account of the Units of such former Member Transferred to such Member.

money; and (c) the liquidation of the Company within the meaning of Treasury Regulations Section 1.704-1(b)(2)(ii)(g). Any such increase or decrease in Book Value of an asset shall be allocated as a
Profit or Loss to the Capital Accounts of the Members under Section 4.2 (determined immediately prior to the event giving rise to the revaluation). 

Section 3.12 Compliance With
Section 1.704-1(b). The provisions of this Agreement relating to the maintenance of Capital Accounts are intended to comply with Treasury Regulations Section 1.704-1(b), and shall be interpreted and applied in a manner consistent with such Treasury Regulations. In the event the Manager shall determine that it is prudent to modify the manner in which the
Capital Accounts are computed in order to comply with such Treasury Regulations, the Manager may make such modification, notwithstanding anything in Section 11.2 to the contrary. The Manager also shall (a) make any
adjustments that are necessary or appropriate to maintain equality between the Capital Accounts of the Members and the amount of the Company capital reflected on the Company’s balance sheet, as computed for book purposes, in accordance with

ARTICLE IV 

DISTRIBUTIONS AND ALLOCATIONS 

Section 4.1 Distributions. 

(a) Tax and Preferred Distributions. 

(i) Tax Distributions. To the extent funds of the Company are legally available for distribution by the Company and such
distribution would not be prohibited under any credit facility to which the Company or any of its Subsidiaries is a party (the “Tax Distribution Conditions”), with respect to each Fiscal Quarter, the Company shall distribute to each
Unitholder, an amount of cash (each a “Tax Distribution”) equal to such Unitholder’s Assumed Tax Liability for such Fiscal Quarter. To the extent a holder of Common Units would receive for any Fiscal Quarter less than its Pro
Rata Share of the aggregate Tax Distributions to be paid pursuant to the preceding sentence, the Tax Distributions to such Unitholder shall be increased to ensure that all Tax Distributions to holders of Common Units are made in accordance with
their Pro Rata Share. The Manager shall be entitled to adjust subsequent Tax Distributions up or down to reflect any variation between its prior estimation of quarterly Tax Distributions and the Tax Distributions that would have been computed under
this Section 4.1(a)(i) based on subsequent information. In the event that due to the Tax Distribution Conditions the funds available for any Tax Distribution to be made hereunder are insufficient to pay the full amount of
the Tax Distribution that would otherwise be required under this Section 4.1(a)(i), the Company shall use its reasonable best efforts to distribute to the Unitholders the amount of funds that are available after application
of the Tax Distribution Conditions on a pro rata basis (according to the amounts that would have been distributed to each Unitholder pursuant to this Section 4.1(a)(i) if available funds (after application of the Tax
Distribution Conditions) existed in a sufficient amount to make such Distribution in full). At any time thereafter when additional funds of the Company are available for Distribution after application of the Tax Distribution Conditions, the Company
shall use its reasonable best efforts to immediately distribute such funds to the Unitholders on a pro rata basis (according to the amounts that would have been distributed to each Unitholder pursuant to this
Section 4.1(a)(i) if available funds (after application of the Tax Distribution Conditions) would have existed in a sufficient amount to make such Tax Distribution in full). 

(ii) Additional Tax Distributions. In the event of any audit by, or similar event with, a taxing authority that affects
the calculation of any Unitholder’s Assumed Tax Liability for any Taxable Year (other than an audit conducted pursuant to the Partnership Tax Audit Rules for which no election is made pursuant to Code Section 6226 (or any similar provision
of state or local law)), or in the event the Company files an amended tax return, each Unitholder’s Assumed Tax Liability with respect to such year shall be 

  
 17 













 
recalculated by giving effect to such event (for the avoidance of doubt, taking into account interest and penalties). Any shortfall in the amount of Tax Distributions the Unitholders and former
Unitholders received for the relevant Taxable Years based on such recalculated Assumed Tax Liability promptly shall be distributed to such Unitholders and the successors of such former Unitholders, except, for the avoidance of doubt, to the extent
Distributions were made to such Unitholders and former Unitholders pursuant to Section 4.1 in the relevant Taxable Years sufficient to cover such shortfall. 

(iii) Convertible Preferred Unit Cash Dividend Distributions. In the event Maravai Co. declares and pays a Convertible
Preferred Stock Cash Dividend, on or before the related dividend payment date (as set forth in the applicable Certificate of Designations), the Manager may cause the Company to make a Distribution of cash in respect of the Convertible Preferred
Units in an amount equal to the related Convertible Preferred Stock Cash Dividend Amount. 
 (iv) Convertible Preferred
Stock Change of Control Repurchase. In the event Maravai Co. is required to make a Convertible Preferred Stock Change of Control Repurchase, on or before the date of the related Change of Control Exchange (as defined in the Certificate of
Designations), the Manager shall cause the Company to make a Distribution of cash in respect of the Convertible Preferred Units in an amount equal to the aggregate Change of Control Price (as defined in the Certificate of Designations) which is to
be paid in cash and not in shares of Class A Common Stock. 
 (v) Convertible Preferred Unit Liquidation Payment.
In the event Maravai Co. makes a Convertible Preferred Stock Liquidation Payment, on or before the related date fixed for liquidation, winding-up or dissolution of Maravai Co., the Manager may cause the
Company to make a Distribution in respect of the Convertible Preferred Units in an amount equal to the related Convertible Preferred Stock Liquidation Payment Amount. 

(vi) Non-Convertible Preferred Unit Cash Distributions. In the event Maravai Co.
makes any Senior Note Payment, the Manager may cause the Company to make a Distribution of cash in respect of the Non-Convertible Preferred Units in an amount equal to the related Senior Note Payment. 

(b) Other Distributions. Except as otherwise set forth in Section 4.1(a), the Manager may (but shall not be
obligated to) make Distributions at such time, in such amounts and in such form (including in-kind property) as determined by the Manager in its sole discretion, in each case to the holders of Common Units
immediately prior to such Distribution on a pro rata basis. 
 Section 4.2 Allocations. Profits or
Losses for any Fiscal Year shall be allocated among the Unitholders in such a manner as to reduce or eliminate, to the extent possible, any difference, as of the end of such Fiscal Year, between (a) the sum of (i) the Capital Account of
each Unitholder, (ii) such Unitholder’s share of Minimum Gain (as determined according to Treasury Regulation Section 1.704-2(g)) and (iii) such Unitholder’s partner nonrecourse debt
minimum gain (as defined in Treasury Regulation Section 1.704-2(i)(2)) and (b) the respective net amounts, positive or negative, which would be distributed to them or for which they would be liable
to the Company 

  
 18 













 
under this Agreement and the Delaware Act, determined as if the Company were to (i) liquidate the assets of the Company for an amount equal to their Book Value and (ii) distribute the
proceeds of such liquidation pursuant to Section 10.2. 
 Section 4.3 Special
Allocations. 
 (a) Minimum Gain Chargeback. Losses attributable to partner nonrecourse debt (as defined in Treasury
Regulation Section 1.704-2(b)(4)) shall be allocated in the manner required by Treasury Regulation Section 1.704-2(i). If there is a net decrease during a
Taxable Year in partner nonrecourse debt minimum gain (as defined in Treasury Regulation Section 1.704-2(i)(2)), Profits for such Taxable Year (and, if necessary, for subsequent Taxable Years) shall be
allocated to the Unitholders in the amounts and of such character as determined according to Treasury Regulation Section 1.704-2(i)(4). 

(b) Unitholder Nonrecourse Debt Minimum Chargeback. Nonrecourse deductions (as determined according to Treasury Regulation Section 1.704-2(b)(1)) for any Taxable Year shall be allocated to each holder of Common Units ratably among such Unitholders based upon their ownership of Common Units. Except as otherwise provided in
Section 4.3(a), if there is a net decrease in the Minimum Gain during any Taxable Year, each Unitholder shall be allocated Profits for such Taxable Year (and, if necessary, for subsequent Taxable Years) in the amounts and
of such character as determined according to Treasury Regulation Section 1.704-2(f). This Section 4.3(b) is intended to be a Minimum Gain chargeback provision that complies with
the requirements of Treasury Regulation Section 1.704-2(f), and shall be interpreted in a manner consistent therewith. 

(c) Qualified Income Offset. If any Unitholder that unexpectedly receives an adjustment, allocation or distribution described in
Treasury Regulation Section 1.704-1(b)(2)(ii)(d)(4), (5) and (6) has an Adjusted Capital Account Deficit as of the end of any Taxable Year, computed after the application of
Section 4.3(a) and Section 4.3(b), but before the application of any other provision of this Article IV, then Profits for such Taxable Year shall be allocated to such Unitholder in
proportion to, and to the extent of, such Adjusted Capital Account Deficit. This Section 4.3(c) is intended to be a qualified income offset provision as described in Treasury Regulation
Section 1.704-1(b)(2)(ii)(d) and shall be interpreted in a manner consistent therewith. 
 (d)
Allocation of Certain Profits and Losses. Profits and Losses described in Section 3.5(b)(v) shall be allocated in a manner consistent with the manner that the adjustments to the Capital Accounts are required to be
made pursuant to Treasury Regulation Section 1.704-1(b)(2)(iv)(j), (k) and (m). 
 (e)
Regulatory Allocations. The allocations set forth in Sections 4.3(a)-(d) (the “Regulatory Allocations”) are intended to comply with certain requirements of Sections
1.704-1(b) and 1.704-2 of the Treasury Regulations. The Regulatory Allocations may not be consistent with the manner in which the Unitholders intend to allocate Profit
and Loss of the Company or make the Company distributions. Accordingly, notwithstanding the other provisions of this Article IV, but subject to the Regulatory Allocations, income, gain, deduction, and loss shall be reallocated among the
Unitholders so as to eliminate the effect of the Regulatory Allocations and thereby 

  
 19 













 
cause the respective Capital Accounts of the Unitholders to be in the amounts (or as close thereto as possible) they would have been if Profit and Loss (and such other items of income, gain,
deduction and loss) had been allocated without reference to the Regulatory Allocations. In general, the Unitholders anticipate that this will be accomplished by specially allocating other Profit and Loss (and such other items of income, gain,
deduction and loss) among the Unitholders so that the net amount of the Regulatory Allocations and such special allocations to each such Unitholder is zero. In addition, if in any Fiscal Year or Fiscal Period there is a decrease in partnership
Minimum Gain, or in partner nonrecourse debt Minimum Gain, and application of the Minimum Gain chargeback requirements set forth in Section 4.3(a) or Section 4.3(b) would cause a distortion in the
economic arrangement among the Unitholders, the Unitholders may, if they do not expect that the Company will have sufficient other income to correct such distortion, request the Internal Revenue Service to waive either or both of such Minimum Gain
chargeback requirements. If such request is granted, this Agreement shall be applied in such instance as if it did not contain such Minimum Gain chargeback requirement. 

(f) The Unitholders acknowledge that allocations like those described in Proposed Treasury Regulations
Section 1.704-1(b)(4)(xii)(c) (“Forfeiture Allocations”) may result from the allocations of Profits and Losses provided for in this Agreement. For the avoidance of doubt, the Company is
entitled to make Forfeiture Allocations and, once required by applicable final or temporary guidance, allocations of Profits and Losses will be made in accordance with Proposed Treasury Regulations
Section 1.704-1(b)(4)(xii)(c) or any successor provision or guidance. 
 (g) Any item of
deduction with respect to a Tax that is offset for a Unitholder under Section 4.6 shall be allocated to the Unitholder in which such payment is to be offset. Any items of deduction (including a deduction described in Code
Sections 707(c) and 162(a)) with respect to or arising from any Convertible Preferred Units shall be allocated to the holders of such Convertible Preferred Units unless such treatment is prohibited by law. For the avoidance of doubt, all tax
deductions described in this Section 4.3(g) shall be taken into account in determining the amount of Tax Distribution made under the provisions of Section 4.1(a)(i). Any items of deduction
(including a deduction described in Code Sections 707(c) and 162(a)) with respect to or arising from the Non-Convertible Preferred Units shall be allocated to the holders of such
Non-Convertible Preferred Units unless such treatment is prohibited by law. 

Section 4.4 Offsetting Allocations. If, and to the extent that, any Member is deemed to recognize any
item of income, gain, deduction or loss as a result of any transaction between such Member and the Company pursuant to Sections 83, 482, or 7872 of the Code or any similar provision now or hereafter in effect, the Manager shall use its commercially
reasonable efforts to allocate any corresponding Profit or Loss to the Member who recognizes such item in order to reflect the Members’ economic interest in the Company. 

Section 4.5 Tax Allocations. 

(a) Allocations Generally. Except as provided in Section 4.5(b) below, for federal, state and local income
Tax purposes, each item of income, gain, loss or deduction shall be allocated among the Unitholders in the same manner and in the same proportion that the corresponding book items have been allocated among the Unitholders’ respective Capital
Accounts; provided that, if any such allocation is not permitted by the Code or other applicable law, then each subsequent 

  
 20 













 
item of income, gains, losses, deductions and credits will be allocated among the Unitholders so as to reflect as nearly as possible the allocation set forth herein in computing their Capital
Accounts. 
 (b) Code Section 704(c) Allocations. Items of the Company taxable income, gain, loss and deduction
with respect to any property contributed to the capital of the Company shall, solely for Tax purposes, be allocated among the Unitholders in accordance with Code Section 704(c) so as to take account of any variation between the adjusted basis
of such asset for federal income Tax purposes and its initial Book Value. Such allocations shall be made using a reasonable method specified in Treasury Regulations Section 1.704-3. In addition, if the
Book Value of any Company asset is adjusted pursuant to the requirements of Treasury Regulation Section 1.704-1(b)(2)(iv)(e) or (f), then subsequent allocations of items of taxable income, gain, loss and
deduction with respect to such asset shall take account of any variation between the adjusted basis of such asset for federal income Tax purposes and its Book Value in the same manner as under Code Section 704(c). Notwithstanding the foregoing,
the Manager shall determine all allocations pursuant to this Section 4.5(b) using any method selected by the Manager that is permitted under Section 704(c) of the Code and the Treasury Regulations thereunder. 

(c) Section 754 Election. The Company will make an election under Section 754 of the Code for its Taxable Year
that includes or begins on the date of this Agreement to adjust the basis of the Company property as permitted and provided in Sections 734 and 743 of the Code. Such election shall be effective solely for federal (and, if applicable, state and
local) income Tax purposes and shall not result in any adjustment to the Book Value of any Company asset or to the Member’s Capital Accounts (except as provided in Treasury Regulations
Section 1.704-1(b)(2)(iv)(m)). 
 (d) Allocation of Tax Credits, Tax Credit Recapture,
Etc. Allocations of Tax credits, Tax credit recapture, and any items related thereto shall be allocated to the Unitholders according to their interests in such items as determined by the Manager taking into account the principles of Treasury
Regulation Section 1.704-1(b)(4)(ii) and (viii). 
 (e) Corrective Allocations. If
necessary, the Company will make corrective allocations as set forth in Treasury Regulation Section 1.704-1(b)(4)(x). 

(f) Effect of Allocations. Allocations pursuant to this Section 4.5 are solely for purposes of federal, state
and local Taxes and shall not affect, or in any way be taken into account in computing, any Unitholder’s Capital Account or share of Profits, Losses, Distributions (other than Tax Distributions) or other items pursuant to any provision of this
Agreement. 
 Section 4.6 Indemnification and Reimbursement for Payments on Behalf of a Unitholder.
Except as otherwise provided in Article VI, if the Company is required by law to make any payment to a Governmental Entity that is specifically attributable to a Unitholder or a Unitholder’s status as such (including federal withholding
Taxes, state personal property Taxes, and state unincorporated business Taxes), then such Unitholder shall indemnify and contribute to the Company in full for the entire amount paid (including interest, penalties and related expenses). The Manager
may offset Distributions to which a Person is otherwise entitled under this Agreement against such Person’s obligation to indemnify the Company under this Section 4.6 or


  
 21 













 
with respect to any other amounts owed by the Unitholder to the Company or any of its Subsidiaries. A Unitholder’s obligation to indemnify and make contributions to the Company under this
Section 4.6 shall survive the termination, dissolution, liquidation and winding up of the Company, and for purposes of this Section 4.6, the Company shall be treated as continuing in existence. The
Company may pursue and enforce all rights and remedies it may have against each Unitholder under this Section 4.6, including instituting a lawsuit to collect such indemnification and contribution, with interest calculated
at a rate equal to the Base Rate plus three percentage points per annum (but not in excess of the highest rate per annum permitted by law), compounded on the last day of each Fiscal Quarter. 

ARTICLE V 
 MANAGEMENT
AND CONTROL OF BUSINESS 
 Section 5.1 Management. 

(a) Except as otherwise specifically provided in this Agreement or the Delaware Act, the business, property and affairs of the Company shall
be managed, operated and controlled at the sole, absolute and exclusive direction of the Manager in accordance with the terms of this Agreement. No Members shall have management authority or voting or other rights over, or any other ability to take
part in the conduct or control of the business of, the Company. The Manager is hereby designated as a “manager” within the meaning of Section 18-101(10) of the Delaware Act. The Manager is, to
the extent of its rights and powers set forth in this Agreement, an agent of the Company for the purpose of the Company’s business, and the actions of the Manager taken in accordance with such rights and powers shall bind the Company (and no
Member shall have such right). The Manager shall have all necessary powers to carry out the purposes, business and objectives of the Company. The Manager may delegate in its discretion the authority to sign agreements and other documents and take
other actions on behalf of the Company to any Person (including any Member, officer or employee of the Company) to enter into and perform any document on behalf of the Company. 

(b) Without limiting Section 5.1(a), the Manager shall have the sole power and authority to effect any of the
following by the Company or any of its Subsidiaries in one or a series of related transaction, in each case without the vote, consent or approval of any Unitholder: (i) any sale, lease, transfer, exchange or other disposition of any, all or
substantially all of the assets of the Company (including the exercise or grant of any conversion, option, privilege or subscription right or any other right available in connection with any assets at any time held by the Company); (ii) any merger,
consolidation, reorganization or other combination of the Company with or into another entity, (iii) any acquisition; (iv) any issuance of debt or equity securities; (v) any incurrence of indebtedness; or (vi) any dissolution.
Except for any vote, consent or approval of any Unitholder expressly required by this Agreement, if a vote, consent or approval of the Unitholders is required by the Delaware Act or other applicable law with respect to any action to be taken by the
Company or matter considered by the Manager, each Unitholder will be deemed to have consented to or approved such action or voted on such matter in accordance with the consent or approval of the Manager on such action or matter. 

(c) Maravai Co. may withdraw as the Manager and appoint as its successor at any time upon written notice to the Company (a) any
wholly-owned Subsidiary of Maravai Co., (b) any 

  
 22 













 
Person of which Maravai Co. is a wholly-owned Subsidiary, (c) any Person into which Maravai Co. is merged or consolidated or (d) any transferee of all or substantially all of the assets
of Maravai Co., which withdrawal and replacement shall be effective upon the delivery of such notice. No appointment of a Person other than Maravai Co. (or its successor, as the case may be) as Manager shall be effective unless Maravai Co. (or its
successor, as the case may be) and the new Manager provide all Members with contractual rights, directly enforceable by such Members against the new Manager, to cause the new Manager to comply with all of the Manager’s obligations under this
Agreement. 
 Section 5.2 Investment Company Act. The Manager shall use reasonable best efforts to
ensure that the Company shall not be subject to registration as an investment company pursuant to the Investment Company Act. 

Section 5.3 Officers. 

(a) Officers. Unless determined otherwise by the Manager, the officers of the Company shall be a Chief Executive Officer, a President,
a Chief Financial Officer, a Treasurer and a Secretary and each other officer of Maravai Co. shall also be an officer of the Company, with the same title. All officers shall be appointed by the Manager (or by the Chief Executive Officer to the
extent the Manager delegates such authority to the Chief Executive Officer) and shall hold office until their successors are appointed by the Manager (or by the Chief Executive Officer to the extent the Manager delegates such authority to the Chief
Executive Officer). Two or more offices may be held by the same individual. The officers of the Company may be removed by the Manager (or by the Chief Executive Officer to the extent the Manager delegates such authority to the Chief Executive
Officer) at any time for any reason or no reason. 
 (b) Other Officers and Agents. The Manager may appoint such other officers and
agents as it may deem necessary or advisable, who shall hold their offices for such terms and shall exercise such powers and perform such duties as shall be determined from time to time by the Manager. 

(c) Chief Executive Officer. The Chief Executive Officer shall be the chief executive officer of the Company and shall have the general
powers and duties of supervision and management usually vested in the office of a chief executive officer of a company. He or she shall preside at all meetings of Members if present thereat. 

(d) President. The President shall be the chief executive officer of the Company in the absence of the Chief Executive Officer. In
general, the President shall perform all duties incident to the office of President and such other duties as may be prescribed from time to time by the Manager. 

(e) Chief Financial Officer. The Chief Financial Officer shall be the chief financial officer of the Company and shall keep and
maintain or cause to be kept and maintained adequate and correct books and records of accounts of the properties and business transactions of the Company. The books of account shall at all times be open to inspection by the Manager. The Chief
Financial Officer shall deposit all monies and other valuables in the name of, and to the credit of, the Company with such depositaries as may be designated by the Manager. 

  
 23 













 (f) Treasurer. The Treasurer shall have the custody of Company funds and securities
and shall keep full and accurate account of receipts and disbursements. He or she shall deposit all moneys and other valuables in the name and to the credit of the Company in such depositaries as may be designated by the Manager or the Chief
Executive Officer. The Treasurer shall disburse the funds of the Company as may be ordered by the Manager or the Chief Executive Officer, taking proper vouchers for such disbursements. He or she shall render to the Manager and the Chief Executive
Officer whenever either of them may request it, an account of all his or her transactions as Treasurer and of the financial condition of the Company. If required by the Manager, the Treasurer shall give the Company a bond for the faithful discharge
of his or her duties in such amount and with such surety as the Manager shall prescribe. 
 (g) Secretary. The Secretary shall give,
or cause to be given, notice of all meetings of Members and all other notices required by applicable law or by this Agreement, and in case of his or her absence or refusal or neglect so to do, any such notice may be given by any person thereunto
directed by the Chief Executive Officer, or by the Manager. He or she shall record all the proceedings of the meetings of the Company, and shall perform such other duties as may be assigned to him or her by the Manager or by the Chief Executive
Officer. 
 (h) Other Officers. Other officers, if any, shall have such powers and shall perform such duties as shall be assigned to
them, respectively, by the Manager or by the Chief Executive Officer. 
 Section 5.4 Fiduciary
Duties. 
 (a) Members and Unitholders. To the fullest extent permitted by law and notwithstanding any duty otherwise
existing at law or in equity, no Member or Unitholder, solely in its capacity as such, shall owe any fiduciary duty to the Company, the Manager, any Member, any Unitholder or any other Person bound by this Agreement, provided that the foregoing
shall not eliminate the implied contractual covenant of good faith and fair dealing. Nothing in this Section 5.4(a) shall limit the liabilities, duties or obligations of any Member or Unitholder acting in his or her
capacity as an officer or manager pursuant to any other provision of this Agreement. 
 (b) Manager and Officers.
Notwithstanding any other provision to the contrary in this Agreement, except as set forth in Section 5.4(c), (i) the Manager shall, in its capacity as Manager, and not in any other capacity, have the same fiduciary duties
to the Company and the Unitholders and Members as a member of the board of directors of a Delaware corporation; and (ii) each officer of the Company shall, in his or her capacity as such, and not in any other capacity, have the same fiduciary
duties to the Company and the Unitholders and Members as an officer of a Delaware corporation. For the avoidance of doubt, the fiduciary duties described in clause (i) above shall not be limited by the fact that the Manager shall be permitted
to take certain actions in its sole or reasonable discretion pursuant to the terms of this Agreement or any agreement entered into in connection herewith. 

(c) Manager Conflicts. The parties hereto acknowledge that the members of Maravai Co.’s board of directors will owe fiduciary
duties to Maravai Co. and its stockholders. The Manager will use commercially reasonable and appropriate efforts and means, as determined in good faith by the Manager, to minimize any conflict of interest between the Members, on the one hand, and


  
 24 













 
the stockholders of Maravai Co., on the other hand, and to effectuate any transaction that involves or affects any of the Company, the Manager, the Members and/or the stockholders of Maravai Co.
in a manner that does not (i) disadvantage the Members of their interests relative to the stockholders of Maravai Co. or (ii) advantage the stockholders of Maravai Co. relative to the Members or (iii) treat the Members and the
stockholders of Maravai Co. differently; provided that in the event of a conflict between the interests of the stockholders of Maravai Co. and the interests of the Members, such Members agree that the Manager shall discharge its fiduciary
duties to such Members by acting in the best interests of Maravai Co.’s stockholders. 
 (d) Waiver. Any duties and liabilities
set forth in this Agreement shall replace those existing at law or in equity and each of the Company, each Member and Unitholder and any other Person bound by this Agreement hereby, to the fullest extent permitted by applicable law, including Section 18-1101(e) of the Delaware Act, waives the right to make any claim, bring any action or seek any recovery based on any duties or liabilities existing at law or in equity other than any such duties and
liabilities set forth in this Agreement. 
 (e) Survival. The provisions of this Section 5.4 shall survive
any amendment, repeal or termination of this Agreement. 
 ARTICLE VI 

EXCULPATION AND INDEMNIFICATION 

Section 6.1 Exculpation. 

(a) Actions in Capacity as a Member or Unitholder. To the fullest extent permitted by applicable law, and except as otherwise expressly
provided herein, no Member, Unitholder (other than the Manager, acting in its capacity as such) or its respective Indemnitees shall be liable to the Company, any Member, any Unitholder or any other Person bound by this Agreement as a result of or
arising out any action of or omission by such Member or Unitholder solely in its capacity as a Member or Unitholder, except to the extent such Obligations arise out of such Member’s (1) material breach of this Agreement or any other
Transaction Document or (2) bad faith violation of the implied contractual covenant of good faith and fair dealing, in each case as determined by a final judgment, order or decree of an arbitrator or a court of competent jurisdiction (which is
not appealable or with respect to which the time for appeal therefrom has expired and no appeal has been perfected). 
 (b) Other
Actions. To the fullest extent permitted by applicable law, and except as otherwise expressly provided herein, including Section 6.5, no Indemnitee shall be liable to the Company, any Member, any Unitholder or any other
Person bound by this Agreement as a result of or arising out of the activities of the Indemnitee on behalf of the Company to the extent within the scope of the authority reasonably believed by such Indemnitee to be conferred on such Indemnitee,
except to the extent such Indemnitee would not be entitled to exculpation or indemnification pursuant to the articles of incorporation and bylaws of Maravai Co. (as the same may be amended from time to time). 

Section 6.2 Indemnification. To the fullest extent permitted by applicable law, each of (a) the
Manager and its managing member Maravai Co., (b) the Unitholders and Members and 

  
 25 













 
their respective Affiliates, (c) the stockholders, members, managers, directors, officers, partners, employees and agents of the Unitholders, Members and their respective Affiliates, and
(d) the officers and directors of Maravai Co., the Manager, the Company and each of their Subsidiaries (each, an “Indemnitee”) shall be indemnified and held harmless by the Company from and against any and all losses, claims, damages,
liabilities, expenses (including legal fees and expenses), judgments, fines, settlements and other amounts arising from any and all claims, demands, actions, suits or proceedings, civil, criminal, administrative or investigative (collectively,
“Obligations”), which at any time may be imposed on, incurred by, or asserted against, the Indemnitee as a result of or arising out of this Agreement, Maravai Co., the Company, their respective assets, businesses or affairs, or the
activities of the Indemnitee on behalf of Maravai Co., the Company or any of their Subsidiaries to the extent within the scope of the authority reasonably believed to be conferred on such Indemnitee; provided, however, that, to the extent such
Indemnitee is not entitled to exculpation with respect to such Obligations pursuant to 6.5, the Indemnitee shall not be entitled to indemnification for any such Obligations to the extent such Indemnitee would not be entitled to exculpation or
indemnification pursuant to the articles of incorporation and bylaws of Maravai Co. (as the same may be amended from time to time); provided further, that, to the extent such Indemnitee is entitled to exculpation with respect to such Obligations
pursuant to 6.5, the Indemnitee shall not be entitled to indemnification for any such Obligations to the extent they arise out of such Indemnitee’s (1) material breach of this Agreement or any other Transaction Document or (2) bad
faith violation of the implied contractual covenant of good faith and fair dealing. The termination of any action, suit or proceeding by judgment, order, settlement, conviction, or upon a plea of nobo contendere, or its equivalent, shall not,
of itself, create a presumption that the Indemnitee was not entitled to indemnification hereunder. Any indemnification pursuant to this Section 6.1(b) shall be made only out of the assets of the Company and no Member shall
have any personal liability on account thereof. 
 Section 6.3 Expenses. Expenses (including
reasonable legal fees and expenses) incurred by an Indemnitee in defending any claim, demand, action, suit or proceeding described in Section 6.1(b) shall, from time to time, be advanced by the Company prior to the final
disposition of such claim, demand, action, suit or proceeding, upon receipt by the Company of an undertaking by or on behalf of the Indemnitee to repay such amount if it shall be determined that the Indemnitee is not entitled to be indemnified as
provided in Section 6.1(b); provided that such undertaking shall be unsecured and interest free and shall be accepted without regard to an Indemnitee’s ability to repay amounts advanced and without regard to an
Indemnitee’s entitlement to indemnification. 
 Section 6.4
Non-Exclusivity; Savings Clause. The indemnification and advancement of expenses set forth in Section 6.1(b) and Section 6.3 shall not be
exclusive of any other rights to which those seeking indemnification or advancement of expenses may be entitled under any other agreement, policy of insurance or otherwise. The indemnification and advancement of expenses set forth in
Section 6.1(b) and Section 6.3 shall continue as to an Indemnitee who has ceased to be a named Indemnitee and shall inure to the benefit of the heirs, executors, administrators, successors and
permitted assigns of such a Person. If Article VI, Section 6.2 or Section 6.3 or any portion hereof shall be invalidated on any ground by any court of competent jurisdiction, then the
Company shall nevertheless exculpate, indemnify and advance expenses each Indemnitee to the fullest extent permitted by any applicable portion of such sections not so invalidated and to the fullest extent permitted by applicable law. The
exculpation, indemnification and advancement of 

  
 26 













 
expenses provisions set forth in Article VI, Section 6.2 and Section 6.3 shall be deemed to be a contract between the Company and each
of the persons constituting Indemnitees at any time while such provisions remain in effect, whether or not such Person continues to serve in such capacity and whether or not such Person is a party hereto. In addition, neither Article VI,
Section 6.2 nor Section 6.3 may be retroactively amended to adversely affect the rights of any Indemnitee arising in connection with any acts, omissions, facts or circumstances occurring prior to
such amendment. 
 Section 6.5 Insurance. The Company may purchase and maintain insurance on behalf
of the Indemnitees against any liability asserted against them and incurred by them in such capacity, or arising out of their status as Indemnitees, whether or not the Company would have the power to indemnify them against such liability under this
Section 6.5. 
 ARTICLE VII 

ACCOUNTING AND RECORDS; TAX MATTERS 

Section 7.1 Accounting and Records. The books and records of the Company shall be made and maintained,
and the financial position and the results of its operations recorded, at the expense of the Company, in accordance with such method of accounting as is determined by the Manager. The books and records of the Company shall reflect all Company
transactions and shall be made and maintained in a manner that is appropriate and adequate for the Company’s business. 

Section 7.2 Preparation of Tax Returns. The Company shall arrange for the preparation and timely
filing of all Tax returns required to be filed by the Company, including making the elections described in Section 7.3. Each Unitholder shall furnish to the Company all pertinent information in its possession relating to
the Company’s operations that is necessary to enable the Company’s income Tax returns to be prepared and filed. 

Section 7.3 Tax Elections. The Taxable Year shall be the Fiscal Year unless the Manager shall
determine otherwise. The Manager shall determine whether to make or revoke any available election pursuant to the Code. Each Unitholder will upon request supply any information necessary to give proper effect to such election. 

Section 7.4 Tax Controversies. 

(a) The Manager shall be the “partnership representative” (or “PR”) of the Company for purposes of the Partnership
Tax Audit Rules, and, as such, (i) shall be authorized to designate any other Person selected by the Manager as the partnership representative and (ii) shall be authorized and required to represent the Company (at the Company’s
expense) in connection with all examinations of the Company’s affairs by Tax authorities, including resulting administrative and judicial proceedings, and to expend the Company’s funds for professional services and reasonably incurred in
connection therewith. Each Unitholder agrees to reasonably cooperate with the Company and to do or refrain from doing any or all things reasonably requested by the Company with respect to the conduct of such proceedings. 

(b) In the event of an audit by the Internal Revenue Service, unless otherwise approved by all of the Members, the PR shall make on a timely
basis, to the extent permissible under applicable law, the election provided by Section 6226(a) of the Partnership Tax Audit Rules to treat a “partnership adjustment” as an adjustment to be taken into account by each Member in


  
 27 













 
accordance with Section 6226(b) of the Partnership Tax Audit Rules. If the election under Section 6226(a) of the of the Partnership Tax Audit Rules is made, the PR shall furnish to each
Member for the year under audit a statement reflecting the Member’s share of the adjusted items as determined in the notice of final partnership adjustment, and each such Member shall take such adjustment into account as required under
Section 6226(b) of the Partnership Tax Audit Rules and shall be liable for any related tax, interest, penalty, addition to tax, or additional amounts. 

(c) In the event of an audit by the Internal Revenue Service, if the PR does not make the election provided by Section 6226(a) of the
Partnership Tax Audit Rules as noted above, the PR shall allocate the burden of any taxes (including, for the avoidance of doubt, any “imputed underpayment” within the meaning of Section 6225 of the Partnership Tax Audit Rules),
penalties, interest and related expenses imposed on the Company pursuant to the Partnership Tax Audit Rules among the Members to whom such amounts are attributable (whether as a result of their status, actions, inactions or otherwise), as reasonably
determined by the PR and each Member shall promptly reimburse the Company in full for the entire amount the PR determines to be attributable to such Member; provided that the Company will also be allowed to recover any amount due from such
Member pursuant to this sentence from any distribution otherwise payable to such Member pursuant to this Agreement. Solely for purposes of determining the current Member(s) to which any taxes or other amounts are attributable under this provision,
references to any Member in this Section 7.4(c) shall include a reference to each Person that previously held the Units currently held by such Member (but only to the extent of such Person’s interest in such Units).

 (d) The PR is authorized to, and shall follow principles (to the extent available) similar to those set forth in
Section 7.4(b) and Section 7.4(c) with respect to any audits by state, local, or foreign tax authorities and any tax liabilities that result therefrom. 

Section 7.5 Code § 83 Safe Harbor Election. 

(a) By executing this Agreement, each Unitholder authorizes and directs the Company to elect to have the “Safe Harbor” described in
the proposed Revenue Procedure set forth in the Internal Revenue Service Notice 2005-43 (the “IRS Notice”) or in any successor, guidance or provision apply to any interest in the Company
transferred to a service provider by the Company on or after the effective date of such Revenue Procedure in connection with services provided to the Company. For purposes of making such Safe Harbor election, the PR is hereby designated as the
“partner who has responsibility for federal income Tax reporting” by the Company and, accordingly, that execution of such Safe Harbor election by the PR constitutes execution of a “Safe Harbor Election” in accordance with
Section 3.03(1) of the IRS Notice. Each Unitholder hereby agrees to comply with all requirements of the Safe Harbor described in the IRS Notice, including, the requirement that each Unitholder shall prepare and file all federal income Tax
returns reporting the income Tax effects of each Unit issued by the Company that qualifies for the Safe Harbor in a manner consistent with the requirements of the IRS Notice. 

(b) Any Unitholder or former Unitholder that fails to comply with requirements set forth in Section 7.5(a) shall
indemnify and hold harmless the Company and each adversely affected Unitholder and former Unitholder from and against any and all losses, liabilities, Taxes, damages, judgments, fines, costs, penalties, amounts paid in settlement and reasonable out-of-pocket costs and expenses incurred in connection therewith (including, costs and expenses of suits and

proceedings, and reasonable fees and disbursements of counsel), in each case resulting from such Unitholder’s or former Unitholder’s failure to comply with such requirements. The
Manager may offset Distributions to which a Person is otherwise entitled under this Agreement against such Person’s obligation to indemnify the Company and any other Person under this Section 7.5(b) (and any amount so
offset with respect to such Person’s obligation to indemnify a Person other than the Company shall be paid over to such other Person by the Company). A Unitholder’s obligations to comply with the requirements of
Section 7.5(a) and to indemnify the Company and any Unitholder or former Unitholder under this Section 7.5(b) shall survive such Unitholder’s ceasing to be a Unitholder of the Company and/or
the termination, dissolution, liquidation and winding up of the Company, and, for purposes of this Section 7.5, the Company shall be treated as continuing in existence. The Company and any Unitholder or former Unitholder
may pursue and enforce all rights and remedies it may have against each Unitholder or former Unitholder under this Section 7.5(b), including (i) instituting a lawsuit to collect such indemnification and contribution,
with interest calculated at a rate equal to the Base Rate plus three percentage points per annum (but not in excess of the highest rate per annum permitted by law), compounded on the last day of each Fiscal Quarter and (ii) specific performance
and/or immediate injunctive or other equitable relief from any court of competent jurisdiction (without the necessity of showing actual money damages, or posting any bond or other security) in order to enforce or prevent any violation of the
provisions of Section 7.5(a). 
 (c) Each Unitholder authorizes the Manager to amend paragraphs (a) and (b)
of this Section 7.5 to the extent necessary to achieve substantially the same Tax treatment with respect to any interest in the Company Transferred to a service provider by the Company in connection with services
provided to the Company as set forth in Section 4 of the IRS Notice (e.g., to reflect changes from the rules set forth in the IRS Notice in subsequent Internal Revenue Service guidance); provided that such amendment is not materially
adverse to any Unitholder (as compared with the after-Tax consequences that would result if the provisions of the IRS Notice applied to all interests in the Company Transferred to a service provider by the
Company in connection with services provided to the Company). 
 ARTICLE VIII 

TRANSFER OF UNITS; ADMISSION OF NEW MEMBERS 

Section 8.1 Transfer of Units. Other than as provided for below in this
Section 8.1, no Member may sell, assign, transfer, grant a participation in, pledge, hypothecate, encumber or otherwise dispose of (such transaction being herein collectively called a “Transfer”) all or any
portion of its Units except with the approval of the Manager, which may be granted or withheld in its sole discretion. Without the approval of the Manager (but otherwise in compliance with Section 8.1), a Member may, at any
time, (a) Transfer any portion of such Member’s Units pursuant to the Exchange Agreement, and (b) Transfer any portion of such Member’s Units to a Permitted Transferee of such Member. Any Transfer of Units to a Permitted
Transferee of such Member by a Member which also holds Class B Common Stock must be accompanied by the transfer of a corresponding number of shares of Class B Common Stock (determined based upon the Exchange Rate then in effect) to such
Permitted Transferee. Any purported Transfer of all or a portion of a Member’s Units not complying with this Section 8.1 shall be void ab initio and shall not create any obligation on the part of the Company or
the other Members to recognize that purported Transfer or to recognize the Person to which the Transfer purportedly was made as a Member. A Person 

  
 29 













 
acquiring a Member’s Units pursuant to this Section 8.1 shall not be admitted as a substituted or Additional Member except in accordance with the requirements of
Section 8.2, but such Person shall, to the extent of the Units transferred to it, be entitled to such Member’s (i) share of Distributions, (ii) share of Profits and Losses and (iii) Capital Account in
accordance with Section 3.5. Notwithstanding anything in this Section 8.1 or elsewhere in this Agreement to the contrary, if a Member Transfers all or any portion of its Units after the designation
of a record date and declaration of a Distribution pursuant to Section 4.1 and before the payment date of such distribution, the transferring Member (and not the Person acquiring all or any portion of its Units) shall be
entitled to receive such Distribution in respect of such transferred Units. 
 Section 8.2 Recognition of
Transfer; Substituted and Additional Members. 
 (a) No direct or indirect Transfer of all or any portion of a Member’s Units
may be made, and no purchaser, assignee, transferee or other recipient of all or any part of such Units shall be admitted to the Company as a substituted or Additional Member hereunder, unless: 

(i) the provisions of Section 8.1 shall have been complied with; 

(ii) in the case of a proposed substituted or Additional Member that is (A) a competitor or potential competitor of
Maravai Co. or the Company or their respective Subsidiaries, (B) a Person with whom Maravai Co. or the Company or their respective Subsidiaries has had or is expected to have a material commercial or financial relationship or (C) likely to
subject Maravai Co. or the Company or their respective Subsidiaries to any material legal or regulatory requirement or obligation, or materially increase the burden thereof, in each case as determined by the Manager in its sole discretion, the
admission of the purchaser, assignee, transferee or other recipient as a substituted or Additional Member shall have been approved by the Manager; 

(iii) the Manager shall have been furnished with the documents effecting such Transfer, in form and substance reasonably
satisfactory to the Manager, executed and acknowledged by both the seller, assignor or transferor and the purchaser, assignee, transferee or other recipient, and the Manager shall have executed (and the Manager hereby agrees to execute) any other
documents on behalf of itself and the Members required to effect the Transfer; 
 (iv) the provisions of
Section 8.2(b) shall have been complied with; 
 (v) the Manager shall be reasonably satisfied that
such Transfer will not (A) result in a violation of the Securities Act or any other applicable law; or (B) cause an assignment under the Investment Company Act; 

(vi) such Transfer would not cause the Company to be treated as a “publicly traded partnership” within the meaning of
Section 7704 of the Code or any other association taxable as a corporation for federal income tax purposes and, without limiting the generality of the foregoing, such Transfer shall not be effected on or through an “established securities
market” or a “secondary market or the substantial equivalent thereof,” as such terms are used in Treas. Reg. § 1.7704-1; 

  
 30 













 (vii) the Manager shall have received the opinion of counsel, if any,
required by Section 8.2(c) in connection with such Transfer; and 
 (viii) all necessary
instruments reflecting such Transfer and/or admission shall have been filed in each jurisdiction in which such filing is necessary in order to qualify the Company to conduct business or to preserve the limited liability of the Members. 

(b) Each Substituted Member and Additional Member shall be bound by all of the provisions of this Agreement. Each Substituted Member and
Additional Member, as a condition to its admission as a Member, shall execute and acknowledge such instruments (including a counterpart of this Agreement and the Exchange Agreement or a joinder agreement in customary form), in form and substance
reasonably satisfactory to the Manager, as the Manager reasonably deems necessary or desirable to effectuate such admission and to confirm the agreement of such substituted or Additional Member to be bound by all the terms and provisions of this
Agreement with respect to the Units acquired by such substituted or Additional Member. The admission of a substituted or Additional Member shall not require the consent of any Member (but shall require the consent of the Manager, if and to the
extent such consent of the Manager is expressly required by this Article VIII). As promptly as practicable after the admission of a substituted or Additional Member, the Unit Ownership Ledger and other books and records of the Company and
Exhibit A shall be changed to reflect such admission. 
 (c) As a further condition to any Transfer of all or any part of a
Member’s Units, the Manager may, in its discretion, require a written opinion of counsel to the transferring Member reasonably satisfactory to the Manager, obtained at the sole expense of the transferring Member, reasonably satisfactory in form
and substance to the Manager, as to such matters as are customary and appropriate in transactions of this type, including, without limitation (or, in the case of any Transfer made to a Permitted Transferee, limited to an opinion) to the effect that
such Transfer will not result in a violation of the registration or other requirements of the Securities Act or any other federal or state securities laws. No such opinion, however, shall be required in connection with a Transfer made pursuant to
the Exchange Agreement. 
 Section 8.3 Expense of Transfer; Indemnification. All reasonable costs
and expenses incurred by the Manager and the Company in connection with any Transfer of a Member’s Units, including any filing and recording costs and the reasonable fees and disbursements of counsel for the Company, shall be paid by the
transferring Member. In addition, the transferring Member hereby indemnifies the Manager and the Company against any losses, claims, damages or liabilities to which the Manager, the Company, or any of their Affiliates may become subject arising out
of or based upon any false representation or warranty made by, or breach or failure to comply with any covenant or agreement of, such transferring Member or such transferee in connection with such Transfer. 

Section 8.4 Exchange Agreement. In connection with any Transfer of any portion of a Member’s
Units pursuant to the Exchange Agreement, the Manager shall cause the Company to take any action as may be required under the Exchange Agreement or requested by any party thereto to effect such Transfer promptly. 

  
 31 













 Section 8.5 Change of Control Transactions. In the
event (i) Maravai Co. enters into an agreement to consummate a Change of Control (as defined in the Tax Receivable Agreement) transaction or (ii) any Person commences a tender offer or exchange offer for any of the outstanding shares of
Maravai Co.’s stock, Maravai Co. will take all reasonable actions in order to effect any Change of Control Exchange (as defined in the Exchange Agreement). 

ARTICLE IX 
 WITHDRAWAL
AND RESIGNATION OF UNITHOLDERS 
 Section 9.1 Withdrawal and Resignation of Unitholders. No
Unitholder shall have the power or right to withdraw or otherwise resign from the Company prior to the dissolution and winding up of the Company pursuant to Article X, without the prior written consent of the Manager (which consent may be
withheld by the Manager in its sole discretion), except as otherwise expressly permitted by this Agreement. Upon a Transfer of all of a Unitholder’s Units in a Transfer permitted by this Agreement, and (if applicable) the Equity Agreements,
such Unitholder shall cease to be a Unitholder. Notwithstanding that payment on account of a withdrawal may be made after the effective time of such withdrawal, any completely withdrawing Unitholder will not be considered a Unitholder for any
purpose after the effective time of such complete withdrawal, and, in the case of a partial withdrawal, such Unitholder’s Capital Account (and corresponding voting and other rights) shall be reduced for all other purposes hereunder upon the
effective time of such partial withdrawal. 
 ARTICLE X 

DISSOLUTION AND LIQUIDATION 

Section 10.1 Dissolution. The Company shall not be dissolved by the admission of Additional Members or
Substituted Members. The Company shall dissolve, and its affairs shall be wound up upon the first of the following to occur: 
 (a) at the
election of the Manager; and 
 (b) the entry of a decree of judicial dissolution of the Company under Section 33.5 of the Delaware Act
or an administrative dissolution under Section 18-802 of the Delaware Act. 
 Except as
otherwise set forth in this Article X the Company is intended to have perpetual existence. An Event of Withdrawal shall not cause a dissolution of the Company and the Company shall continue in existence subject to the terms and conditions of
this Agreement. 
 Section 10.2 Liquidation and Termination. On the dissolution of the Company, the
Manager shall act as liquidator or may appoint one or more representatives, Members or other Persons as liquidator(s). The liquidators shall proceed diligently to wind up the affairs of the Company and make final distributions as provided herein and
in the Delaware Act. The costs of liquidation shall be borne as the Company’s expense. Until final distribution, the liquidators shall continue to operate the Company properties with all of the power and authority of the Manager. The steps to
be accomplished by the liquidators are as follows: 
 (a) The liquidators shall pay, satisfy or discharge from the Company’s funds all
of the debts, liabilities and obligations of the Company (including all expenses incurred in liquidation) 

  
 32 













 
or otherwise make adequate provision for payment and discharge thereof (including the establishment of a cash fund for contingent liabilities in such amount and for such term as the liquidators
may reasonably determine). 
 (b) As promptly as practicable after dissolution, the liquidators shall (i) determine the Fair Market
Value (the “Liquidation FMV”) of the Company’s remaining assets (the “Liquidation Assets”) in accordance with Article X hereof, (ii) determine the amounts to be distributed to each Unitholder in
accordance with Section 4.1, and (iii) deliver to each Unitholder a statement (the “Liquidation Statement”) setting forth the Liquidation FMV and the amounts and recipients of such Distributions, which
Liquidation Statement shall be final and binding on all Unitholders. 
 (c) As soon as the Liquidation FMV and the proper amounts of
Distributions have been determined in accordance with Section 10.2(b) above, the liquidators shall promptly distribute the Company’s Liquidation Assets to the holders of Units in accordance with
Section 4.1(b) above. In making such distributions, the liquidators shall allocate each type of Liquidation Assets (i.e., cash or cash equivalents, preferred or common equity securities, etc.) among the Unitholders ratably
based upon the aggregate amounts to be distributed with respect to the Units held by each such holder; provided that the liquidators may allocate each type of Liquidation Assets so as to give effect to and take into account the relative priorities
of the different Units; provided further that, in the event that any securities are part of the Liquidation Assets, each Unitholder that is not an “accredited investor” as such term is defined under the Securities Act may, in
the sole discretion of the Manager, receive, and hereby agrees to accept, in lieu of such securities, cash consideration with an equivalent value to such securities as determined by the Manager. Any non-cash
Liquidation Assets will first be written up or down to their Fair Market Value, thus creating Profit or Loss (if any), which shall be allocated in accordance with Section 4.2 and Section 4.3. If
any Unitholder’s Capital Account is not equal to the amount to be distributed to such Unitholder pursuant to Section 10.2(b), Profits and Losses for the Fiscal Year in which the Company is dissolved shall be allocated
among the Unitholders in such a manner as to cause, to the extent possible, each Unitholder’s Capital Account to be equal to the amount to be distributed to such Unitholder pursuant to Section 10.2(b). The distribution
of cash and/or property to a Unitholder in accordance with the provisions of this Section 10.2(b) constitutes a complete return to the Unitholder of its Capital Contributions and a complete distribution to the Unitholder of
its interest in the Company and all the Company property and constitutes a compromise to which all Unitholders have consented within the meaning of the Delaware Act. To the extent that a Unitholder returns funds to the Company, it has no claim
against any other Unitholder for those funds. 
 Section 10.3 Securityholders Agreement. To the
extent that units or other equity securities of any Subsidiary are distributed to any Unitholders and unless otherwise agreed to by the Manager, such Unitholders hereby agree to enter into a securityholders agreement with such Subsidiary and each
other Unitholder which contains rights and restrictions in form and substance similar to the provisions and restrictions set forth herein (including in Article VIII). 

Section 10.4 Cancellation of Certificate. On completion of the distribution of the Company’s
assets as provided herein, the Company shall be terminated (and the Company shall not be terminated prior to such time), and the Manager (or such other Person or Persons as the Delaware Act may require or permit) shall file a certificate of
cancellation with the Secretary of 

  
 33 













 
State of Delaware, cancel any other filings made pursuant to this Agreement that are or should be canceled and take such other actions as may be necessary to terminate the Company. The Company
shall be deemed to continue in existence for all purposes of this Agreement until it is terminated pursuant to this Section 10.4. 

Section 10.5 Reasonable Time for Winding Up. A reasonable time shall be allowed for the orderly
winding up of the business and affairs of the Company and the liquidation of its assets pursuant to Section 10.2 in order to minimize any losses otherwise attendant upon such winding up. 

Section 10.6 Return of Capital. The liquidators shall not be personally liable for the return of
Capital Contributions or any portion thereof to the Unitholders (it being understood that any such return shall be made solely from the Company assets). 

Section 10.7 Hart-Scott-Rodino. In the event the Hart-Scott-Rodino Antitrust Improvements Act of 1976
(the “HSR Act”) is applicable to any Unitholder, the dissolution of the Company shall not be consummated until such time as the applicable waiting period (and extensions thereof) under the HSR Act have expired or otherwise been terminated
with respect to each such Unitholder. 
 ARTICLE XI 

GENERAL PROVISIONS 

Section 11.1 Power of Attorney. Each Unitholder hereby constitutes and appoints the Manager and the
liquidators, if any and as applicable, and their respective designees, with full power of substitution, as his, her or its true and lawful agent and attorney-in-fact,
with full power and authority in his, her or its name, place and stead, to execute, swear to, acknowledge, deliver, file and record in the appropriate public offices (to the same extent such Person could take such action): (a) this Agreement, all
certificates and other instruments and all amendments hereof or thereof in accordance with the terms hereof which the Manager deems appropriate or necessary to form, qualify, or continue the qualification of, the Company as a limited liability
company in the State of Delaware and in all other jurisdictions in which the Company may conduct business or own property or as otherwise permitted herein; (b) all instruments, agreements, amendments or other documents which the Manager 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 Manager and/or the liquidators deems
appropriate or necessary to reflect the dissolution and liquidation of the Company 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 Unitholder pursuant to Article VIII or Article IX. The foregoing power of attorney is irrevocable and coupled with an interest, and shall survive the death, disability, incapacity, dissolution, bankruptcy, insolvency or
termination of any Unitholder and the Transfer of all or any portion of his, her or its Units and shall extend to such Unitholder’s heirs, successors, permitted assigns and personal representatives. 

Section 11.2 Amendments. This Agreement may be amended (including, for purposes of this
Section 11.2, any amendment effected directly or indirectly by way of a merger or consolidation of the Company) or waived, in whole or in part, by the Manager; provided, however,


  
 34 













 
that to the extent any amendment or waiver, including any amendment or waiver of the Exhibits attached hereto, would disproportionately and adversely affect the rights of any Member of a class
compared with the rights of any other Member of such class, such amendment or waiver may only be made by the Manager upon the prior written consent of such disproportionately and adversely affected Member. 

Section 11.3 Title to the Company Assets. The Company’s assets shall be deemed to be owned by the
Company as an entity, and no Unitholder, individually or collectively, shall have any ownership interest in such assets or any portion thereof. Legal title to any or all of such assets may be held in the name of the Company or one or more nominees,
as the Manager may determine. The Manager hereby declares and warrants that any Company assets for which legal title is held in the name of any nominee shall be held in trust by such nominee for the use and benefit of the Company in accordance with
the provisions of this Agreement. All the Company assets shall be recorded as the property of the Company on its books and records, irrespective of the name in which legal title to such assets is held. 

Section 11.4 Remedies. Each Unitholder and the Company shall have all rights and remedies set forth in
this Agreement and all rights and remedies which such Person has been granted at any time under any other agreement or contract and all of the rights which such Person has under any law. Any Person having any rights under any provision of this
Agreement or any other agreements contemplated hereby shall be entitled to enforce such rights specifically (without posting a bond or other security), to recover damages by reason of any breach of any provision of this Agreement and to exercise all
other rights granted by law. 
 Section 11.5 Successors and Assigns. All covenants and agreements
contained in this Agreement shall bind and inure to the benefit of the parties hereto and their respective heirs, executors, administrators, successors, legal representatives and permitted assigns, whether so expressed or not. 

Section 11.6 Severability. Whenever possible, each provision of this Agreement will be interpreted in
such manner as to be effective and valid under applicable law, but if any provision of this Agreement is held to be invalid, illegal or unenforceable in any respect under any applicable law or rule in any jurisdiction, such invalidity, illegality or
unenforceability will not affect any other provision or the effectiveness or validity of any provision in any other jurisdiction, and this Agreement will be reformed, construed and enforced in such jurisdiction as if such invalid, illegal or
unenforceable provision had never been contained herein or if such term or provision could be drawn more narrowly so as not to be illegal, invalid, prohibited or unenforceable in such jurisdiction, it shall be so narrowly drawn, as to such
jurisdiction, without invalidating the remaining terms and provisions of this Agreement or affecting the legality, validity or enforceability of such term or provision in any other jurisdiction. 

Section 11.7 Counterparts; Binding Agreement. This Agreement may be executed simultaneously in two or
more separate counterparts, any one of which need not contain the signatures of more than one party, but each of which will be an original and all of which together shall constitute one and the same agreement binding on all the parties hereto. This
Agreement and all of the provisions hereof shall be binding upon and effective as to each Person who (a) executes this Agreement in the appropriate space provided in the signature pages hereto notwithstanding


  
 35 













 
the fact that other Persons who have not executed this Agreement may be listed on the signature pages hereto and (b) may from time to time become a party to this Agreement by executing a
counterpart of or joinder to this Agreement. 
 Section 11.8 Descriptive Headings; Interpretation.
The descriptive headings of this Agreement are inserted for convenience only and do not constitute a substantive part of this Agreement. Whenever required by the context, any pronoun used in this Agreement shall include the corresponding masculine,
feminine or neuter forms, and the singular form of nouns, pronouns and verbs shall include the plural and vice versa. The use of the word “including” in this Agreement shall be by way of example rather than by limitation. Reference to any
agreement, document or instrument means such agreement, document or instrument as amended or otherwise modified from time to time in accordance with the terms thereof, and if applicable hereof. Whenever required by the context, references to a
Fiscal Year shall refer to a portion thereof. The use of the words “or,” “either” and “any” shall not be exclusive. The parties hereto have participated jointly in the negotiation and drafting of this Agreement. In the
event an ambiguity or question of intent or interpretation arises, this Agreement shall be construed as if drafted jointly by the parties hereto, and no presumption or burden of proof shall arise favoring or disfavoring any party by virtue of the
authorship of any of the provisions of this Agreement. Wherever a conflict exists between this Agreement and any other agreement, this Agreement shall control but solely to the extent of such conflict. 

Section 11.9 Applicable Law. This Agreement shall be governed by, and construed in accordance with,
the laws of the State of Delaware, without giving effect to any choice of law or conflict of law rules or provisions (whether of the State of Delaware or any other jurisdiction) that would cause the application of the laws of any jurisdiction other
than the State of Delaware. 
 Section 11.10 Addresses and Notices. All notices, demands or other
communications to be given or delivered under or by reason of the provisions of this Agreement shall be in writing and shall be deemed to have been given or made when (a) delivered personally to the recipient, (b) telecopied to the
recipient, or delivered by means of electronic mail (with hard copy sent to the recipient by reputable overnight courier service (charges prepaid) that same day) if telecopied/emailed before 5:00 p.m. San Diego, California time on a Business Day,
and otherwise on the next Business Day, or (c) one (1) Business Day after being sent to the recipient by reputable overnight courier service (charges prepaid). Such notices, demands and other communications shall be sent to the address for such
recipient set forth in the Company’s books and records, or to such other address or to the attention of such other person as the recipient party has specified by prior written notice to the sending party. 

Section 11.11 Creditors. None of the provisions of this Agreement shall be for the benefit of or
enforceable by any creditors of the Company or any of its Affiliates, and no creditor who makes a loan to the Company or any of its Affiliates may have or acquire (except pursuant to the terms of a separate agreement executed by the Company in favor
of such creditor) at any time as a result of making the loan any direct or indirect interest in the Company’s Profits, Losses, Distributions, capital or property other than as a secured creditor. Notwithstanding the foregoing, each of the
Indemnitees are intended third party beneficiaries of Section 6.1(b) and shall be entitled to enforce such provision (as it may be in effect from time to time). 

  
 36 













 Section 11.12 No Waiver. No failure by any party to
insist upon the strict performance of any covenant, duty, agreement or condition of this Agreement or to exercise any right or remedy consequent upon a breach thereof shall constitute a waiver of any such breach or any other covenant, duty,
agreement or condition. 
 Section 11.13 Further Action. The parties agree to execute and deliver
all documents, provide all information and take or refrain from taking such actions as may be necessary or appropriate to achieve the purposes of this Agreement. 

Section 11.14 Entire Agreement. This Agreement and the other Transaction Documents embody the complete
agreement and understanding among the parties with respect to the subject matter herein and supersede and preempt any prior understandings, agreements or representations by or among the parties, written or oral, which may have related to the subject
matter hereof in any way. 
 Section 11.15 Delivery by Electronic Means. This Agreement, the
agreements referred to herein, and each other agreement or instrument entered into in connection herewith or therewith or contemplated hereby or thereby, and any amendments hereto or thereto, to the extent signed and delivered by means of a
facsimile machine or electronic transmission in portable document format (pdf) or comparable electronic transmission, shall be treated in all manner and respects as an original agreement or instrument and shall be considered to have the same binding
legal effect as if it were the original signed version thereof delivered in person. At the request of any party hereto or to any such agreement or instrument, each other party hereto or thereto shall
re-execute original forms thereof and deliver them to all other parties. No party hereto or to any such agreement or instrument shall raise the use of a facsimile machine or pdf electronic transmission or
comparable electronic transmission to deliver a signature or the fact that any signature or agreement or instrument was transmitted or communicated through the use of a facsimile machine as a defense to the formation or enforceability of a contract
and each such party forever waives any such defense. 
 Section 11.16 Certain Acknowledgments. This
Agreement shall be considered for all purposes as having been prepared through the joint efforts of the parties. No presumption shall apply in favor of any party in the interpretation of this Agreement or in the resolution of any ambiguity of any
provision hereof based on the preparation, substitution, submission or other event of negotiation, drafting or execution hereof. Each Member and Unitholder acknowledges that it/he/she is entitled to and has been afforded the opportunity to consult
legal counsel of its choice regarding the terms, conditions and legal effects of this Agreement, as well as the advisability and propriety thereof. Each Member and Unitholder further acknowledges that having so consulted with legal counsel of its
choosing, such Member or Unitholder hereby waives any right to raise or rely upon the lack of representation or effective representation in any future proceedings or in connection with any future claim resulting from this Agreement or the formation
of the Company. THE COMPANY, THE MEMBERS AND THE UNITHOLDERS ACKNOWLEDGE THAT KIRKLAND & ELLIS LLP HAS ONLY REPRESENTED THE COMPANY WITH RESPECT TO THE NEGOTIATION AND PREPARATION OF THIS AGREEMENT, AND HAS NOT REPRESENTED THE MEMBERS OR
THE UNITHOLDERS WITH RESPECT TO SUCH MATTERS. 

  
 37 













 Section 11.17 Consent to Jurisdiction; WAIVER OF TRIAL BY
JURY. 
 (a) Consent to Jurisdiction. Each Unitholder irrevocably submits to the exclusive jurisdiction of the United States
District Court for the State of Delaware and the state courts of the State of Delaware for the purposes of any suit, action or other proceeding arising out of this Agreement or any transaction contemplated hereby. Each Unitholder further agrees that
service of any process, summons, notice or document by United States certified or registered mail (in each such case, prepaid return receipt requested) to such Unitholder’s respective address set forth in the Company’s books and records or
such other address or to the attention of such other person as the recipient party has specified by prior written notice to the sending party shall be effective service of process in any action, suit or proceeding in Delaware with respect to any
matters to which it has submitted to jurisdiction as set forth above in the immediately preceding sentence. Each Unitholder irrevocably and unconditionally waives any objection to the laying of venue of any action, suit or proceeding arising out of
this Agreement or the transactions contemplated hereby in the United States District Court for the State of Delaware or the state courts of the State of Delaware and hereby irrevocably and unconditionally waives and agrees not to plead or claim in
any such court that any such action, suit or proceeding brought in such court has been brought in an inconvenient forum. 
 (b) WAIVER OF
TRIAL BY JURY. BECAUSE DISPUTES ARISING IN CONNECTION WITH COMPLEX TRANSACTIONS ARE MOST QUICKLY AND ECONOMICALLY RESOLVED BY AN EXPERIENCED AND EXPERT PERSON AND THE PARTIES WISH APPLICABLE STATE AND FEDERAL LAWS TO APPLY (RATHER THAN
ARBITRATION RULES), THE PARTIES DESIRE THAT THEIR DISPUTES BE RESOLVED BY A JUDGE APPLYING SUCH APPLICABLE LAWS. THEREFORE, TO ACHIEVE THE BEST COMBINATION OF THE BENEFITS OF THE JUDICIAL SYSTEM AND OF ARBITRATION, EACH PARTY TO THIS AGREEMENT
(INCLUDING THE COMPANY) HEREBY WAIVES ALL RIGHTS TO TRIAL BY JURY IN ANY ACTION, SUIT, OR PROCEEDING BROUGHT TO RESOLVE ANY DISPUTE BETWEEN OR AMONG ANY OF THE PARTIES HERETO, WHETHER ARISING IN CONTRACT, TORT, OR OTHERWISE, ARISING OUT OF,
CONNECTED WITH, RELATED OR INCIDENTAL TO THIS AGREEMENT, THE TRANSACTIONS CONTEMPLATED HEREBY AND/OR THE RELATIONSHIPS ESTABLISHED AMONG THE PARTIES HEREUNDER. 

Section 11.18 Representations and Warranties. By execution of this Agreement, each Member severally
represents and warrants as follows: 
 (a) Such Member has full legal right, power, and authority to deliver this Agreement and the other
Transaction Documents and to perform such Member’s obligations hereunder and thereunder; 
 (b) This Agreement and the other
Transaction Documents constitute the legal, valid, and binding obligation of such Member enforceable in accordance with its respective terms, except as the enforcement thereof may be limited by bankruptcy and other laws of general application
relating to creditors’ rights or general principles of equity; 

  
 38 













 (c) Neither this Agreement nor the other Transaction Documents violate, conflict with,
result in a breach of the terms, conditions or provisions of, or constitute a default or an event of default under any other agreement of which such Member is a party; and 

(d) Such Member’s investment in Units in the Company is made for such Member’s own account for investment purposes only and not with
a view to the resale or distribution of such Units. 
 Section 11.19 Tax Receivable Agreement. The
Tax Receivable Agreement and the Exchange Agreement shall each be treated as part of this Agreement as described in Section 761(c) of the Code, and Treas. Reg. § 1.704-1(b)(2)(ii)(h) and § 1.761-1(c) with respect to payments to a Member with respect to an Exchange (as defined in the Tax Receivable Agreement) by such Member.
