3. Agreements to Sell and Purchase. Each Selling Stockholder, severally and not jointly, hereby agrees to sell to the several Underwriters, and each Underwriter, upon the basis of the representations and warranties herein contained, but subject to the terms and conditions hereinafter stated, agrees, severally and not jointly, to purchase from such Selling Stockholder at $[•] a share (the “Purchase Price”) the number of Shares (subject

to such adjustments to eliminate fractional shares as you may determine) that bears the same proportion to the number of Shares to be sold by such Selling Stockholder as the number of Shares set forth in Schedule II hereto opposite the name of such Underwriter bears to the total number of Shares.

On the basis of the representations and warranties contained in this Agreement, and subject to its terms and conditions, each Selling Stockholder, severally and not jointly, agrees, as and to the extent indicated in Schedule I hereto, to sell to the Underwriters the Additional Shares, and the Underwriters shall have the right to purchase, severally and not jointly, up to 3,000,000 Additional Shares at the Purchase Price, provided, however, that the amount paid by the Underwriters for any Additional Shares shall be reduced by an amount per share equal to any dividends declared by the Company and payable on the Firm Shares but not payable on such Additional Shares.

5. Payment and Delivery. Payment for the Firm Shares shall be made to the Selling Stockholders, in each case, in Federal or other funds immediately available in New York City against delivery of such Firm Shares for the respective accounts of the several Underwriters at [•] a.m., New York City time, on September [•], 2021, or at such other time on the same or such other date, not later than September [•], 2021, as shall be designated in writing by Morgan Stanley.

(l) The Company will deliver to each Underwriter (or its agent), on or prior to the date of execution of this Agreement, a properly completed and executed Certification Regarding Beneficial Owners of Legal Entity Customers, together with copies of identifying documentation, and the Company undertakes to provide such additional supporting documentation as each Underwriter may reasonably request in connection with the verification of the foregoing Certification.

(m)

(i) Each of the Maravai Parties also covenants with each Underwriter that, without the prior written consent of at least two of the Representatives (provided that each Representative shall have been informed of and given a reasonable opportunity to give or withhold consent to any such waiver request) (such consent and notice, the “Requisite Consent”) on behalf of the Underwriters, it will not, and will not publicly disclose an intention to, during the period ending on and including the 60th day after the date of the Prospectus (the “Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock (collectively, “Lock-Up Securities”), including units of Maravai Topco Holdings, LLC (the “Units”), or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of any Lock-Up Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other Lock-Up Securities, in cash or otherwise or (3) file or confidentially submit any registration statement with the Commission relating to the offering of any shares of Common Stock or any securities convertible into or exercisable or exchangeable for Common Stock.

(ii) The restrictions contained in the preceding Section 7(m)(i) shall not apply to (A) the Shares to be sold hereunder, (B) the issuance by the Company of shares of Common Stock upon the exercise of an option or warrant or the conversion of a security outstanding on the date hereof as described in the Time of Sale Prospectus, (C) the issuance of shares, and options to purchase shares, of Common Stock and restricted stock units pursuant to stock option plans, stock purchase or other equity incentive plans described in the Time of Sale Prospectus, as those plans are in effect on the date of this Agreement, (D) the sale or issuance of or entry into an agreement providing for the sale or issuance of Common Stock or securities convertible into, exercisable for or which are otherwise exchangeable for or represent the right to receive Common Stock in connection with (x) the acquisition by the Company or any of its subsidiaries of the securities, business, technology, property or other assets of another person or entity or pursuant to an employee benefit plan assumed by the Company in connection with such acquisition, and the issuance of any Common Stock or securities convertible into, exercisable for or which are otherwise exchangeable for or represent the right to receive Common Stock pursuant to any such agreement or (y) the Company’s joint ventures, commercial relationships and other strategic transactions, provided that the aggregate number of shares of Common

Stock securities convertible into, exercisable for or which are otherwise exchangeable for or represent the right to receive Common Stock that the Company may sell or issue or agree to sell or issue pursuant to this clause (D) shall not exceed 7.5% of the total number of shares of Common Stock outstanding as of the Closing Date immediately following the completion of the transactions contemplated by this Agreement to be completed as of that date, including the Transactions, and provided further that all recipients of any such securities shall enter into a “lock-up” agreement, substantially in the form of Exhibit A hereto covering the remainder of the Restricted Period, (E) facilitating the establishment of a trading plan on behalf of a stockholder, officer or director of the Company pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Class A Common Stock, provided that (i) such plan does not provide for the transfer of Class A Common Stock during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Class A Common Stock may be made under such plan during the Restricted Period, or (F) the filing of any registration statement on Form S-8 relating to securities granted or to be granted pursuant to any compensation benefit plan described in clause (C).

During the Restricted Period, the Company shall enforce and not waive or amend, such Company Transfer Restrictions and stop transfer instructions unless the Company shall have obtained the Requisite Consent of the Representatives; provided that this Section 7(n) shall not prohibit the Company from effecting a waiver or amendment to permit a transfer of Lock-Up Securities which is permissible under the terms of the lock-up letters described in Section 6(i) hereof.

8. Covenants of the Selling Stockholders. Each Selling Stockholder, severally and not jointly, covenants with each Underwriter as follows:

(a) Each Selling Stockholder will deliver to each Underwriter (or its agent), prior to or at the Closing Date, a properly completed and executed Internal Revenue Service (“IRS”) Form W-9 or an IRS Form W-8, as appropriate, together with all required attachments to such form.

(b) Each Selling Stockholder will deliver to each Underwriter (or its agent), on the date of execution of this Agreement, a properly completed and executed Certification Regarding Beneficial Owners of Legal Entity Customers, together with copies of identifying documentation, and each Selling Stockholder undertakes to provide such additional supporting documentation as each Underwriter may reasonably request in connection with the verification of the foregoing Certification.

9. Covenants of the Underwriters. Each Underwriter, severally and not jointly, covenants with the Maravai Parties not to take any action that would result in the Company being required to file with the Commission under Rule 433(d) a free writing prospectus prepared by or on behalf of such Underwriter that otherwise would not be required to be filed by the Company thereunder, but for the action of the Underwriter.

10. Indemnity and Contribution. (a) The Maravai Parties and the Selling Stockholders, severally and not jointly, agree to indemnify and hold harmless each Underwriter, its directors, officers, and each person, if any, who controls any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act and each affiliate of any Underwriter participating in the offering within the meaning of Rule 405 under the Securities Act from and against any and all losses, claims, damages and liabilities (including, without limitation, any legal or other expenses reasonably incurred in connection with defending or investigating any such action or claim) that arise out of, or are based upon, any untrue statement or alleged untrue statement of a material fact contained in the Registration Statement or any amendment thereof, any preliminary prospectus, the Time of Sale Prospectus or any amendment or supplement thereto, any issuer free writing prospectus as defined in Rule 433(h) under the Securities Act, any Company information that the Company has filed, or is required to file, pursuant to Rule 433(d) under the Securities Act, any road show as defined in Rule 433(h) under the Securities Act (a “road show”), the Prospectus or any amendment or supplement thereto, or any Testing-the-Waters Communication, or arise out of, or are based upon, any omission or alleged omission to state therein a material fact required to be stated therein or necessary to make the statements therein not misleading, except insofar as such losses, claims, damages or liabilities arise out of, or are based upon, any such untrue statement or omission or alleged untrue statement or omission made in reliance upon and in conformity with any information relating to any Underwriter furnished to the Maravai Parties in writing by such Underwriter through the Representatives expressly for use therein; it being understood and agreed that the only such information furnished by the Underwriters through the Representatives consists of the information described as such in paragraph (b) below.

(b) Each Underwriter agrees, severally and not jointly, to indemnify and hold harmless the Selling Stockholders, the Maravai Parties, each of their directors, their officers who sign the Registration Statement and each person, if any, who controls such Maravai Party or any Selling Stockholder within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act to the same extent as the foregoing indemnity from the Maravai Parties to such Underwriter, but only with reference to information relating to such

Underwriter furnished to the Maravai Parties in writing by such Underwriter through the Representatives expressly for use in the Registration Statement, any preliminary prospectus, the Time of Sale Prospectus, any issuer free writing prospectus, road show, the Prospectus or any amendment or supplement thereto, it being understood and agreed that the only such information furnished by any Underwriter through the Representatives consists of the following information under the caption “Underwriters” in the Time of Sale Prospectus and the Prospectus: the concession figure in the third paragraph, the information regarding stabilization and short positions in the twelfth paragraph (for the avoidance of doubt, such paragraph begins with the words: “In order to facilitate the offering of the Class A common stock, the underwriters may engage in transactions that stabilize, maintain or otherwise affect ….” ) and the information regarding internet distributions in the fourteenth paragraph (for the avoidance of doubt, such paragraph begins with the words: “A prospectus in electronic format may be made available on websites maintained by one or more underwriters …”).

(c) In case any proceeding (including any governmental investigation) shall be instituted involving any person in respect of which indemnity may be sought pursuant to Section 10(a) or 10(b), such person (the “indemnified party”) shall promptly notify the person against whom such indemnity may be sought (the “indemnifying party”) in writing and the indemnifying party, upon request of the indemnified party, shall retain counsel reasonably satisfactory to the indemnified party to represent the indemnified party and any others the indemnifying party may designate in such proceeding and shall pay the reasonably incurred fees and disbursements of such counsel related to such proceeding. In any such proceeding, any indemnified party shall have the right to retain its own counsel, but the fees and expenses of such counsel shall be at the expense of such indemnified party unless (i) the indemnifying party and the indemnified party shall have mutually agreed in writing to the retention of such counsel, (ii) the named parties to any such proceeding (including any impleaded parties) include both the indemnifying party and the indemnified party and representation of both parties by the same counsel would be inappropriate due to actual or potential differing interests between them or one party shall have reasonably concluded that there may be legal defenses available to it that are different from or in addition to those available to the other party or (iii) the indemnifying party has failed within a reasonable time to retain counsel reasonably satisfactory to the indemnified party. It is understood that the indemnifying party shall not, in respect of the legal expenses of any indemnified party in connection with any proceeding or related proceedings in the same jurisdiction, be liable for (i) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Underwriters and all persons, if any, who control any Underwriter within the meaning of either Section 15 of the Securities Act or Section 20 of the Exchange Act or who are affiliates of any Underwriter within the meaning of Rule 405 under the Securities Act, (ii) the fees and expenses of more than one separate firm (in addition to any local counsel) for the Company, its directors, its officers who sign the Registration Statement and each person, if any, who controls the Company within

the meaning of either such Section and (iii) the fees and expenses of more than one separate firm (in addition to any local counsel) for all Selling Stockholders and all persons, if any, who control any Selling Stockholder within the meaning of either such Section and that all such fees and expenses shall be reimbursed as they are incurred. In the case of any such separate firm for the Underwriters and such control persons and affiliates of any Underwriters, such firm shall be designated in writing by the Underwriters. In the case of any such separate firm for any Maravai Party, and such directors, officers and control persons of such Maravai Party, such firm shall be designated in writing by the such Maravai Party. In the case of any such separate firm for the Selling Stockholders and such control persons of any Selling Stockholders, such firm shall be designated in writing by the Selling Stockholders representing a majority of the shares sold by the Selling Stockholders in the offering contemplated hereby. The indemnifying party shall not be liable for any settlement of any proceeding effected without its written consent, but if settled with such consent or if there be a final judgment for the plaintiff, the indemnifying party agrees to indemnify the indemnified party from and against any loss or liability by reason of such settlement or judgment. Notwithstanding the foregoing sentence, if at any time an indemnified party shall have requested an indemnifying party to reimburse the indemnified party for reasonable fees and expenses of counsel as contemplated by the second and third sentences of this paragraph, the indemnifying party agrees that it shall be liable for any settlement of any proceeding effected without its written consent if (i) such settlement is entered into more than 30 days after receipt by such indemnifying party of the aforesaid request and (ii) such indemnifying party shall not have reimbursed the indemnified party in accordance with such request prior to the date of such settlement. No indemnifying party shall, without the prior written consent of the indemnified party, effect any settlement of any pending or threatened proceeding in respect of which any indemnified party is or could have been a party and indemnity could have been sought hereunder by such indemnified party, unless such settlement (i) includes an unconditional release of such indemnified party from all liability on claims that are the subject matter of such proceeding and (ii) does not include a statement as to or an admission of fault, culpability or failure to act by or on behalf of any indemnified party.

(d) To the extent the indemnification provided for in Section 10(a) or 10(b) is unavailable to an indemnified party or insufficient in respect of any losses, claims, damages or liabilities referred to therein, then each indemnifying party under such paragraph, in lieu of indemnifying such indemnified party thereunder, shall contribute to the amount paid or payable by such indemnified party as a result of such losses, claims, damages or liabilities (i) in such proportion as is appropriate to reflect the relative benefits received by the indemnifying party or parties on the one hand and the indemnifying party or parties on the other hand from the offering of the Shares or (ii) if the allocation provided by clause 10(d)(i) above is not permitted by applicable law, in such proportion as is appropriate to reflect not only the relative benefits referred to in clause 10(d)(i) above but also the relative fault of the indemnifying party or

parties on the one hand and of the indemnified party or parties on the other hand in connection with the statements or omissions that resulted in such losses, claims, damages or liabilities, as well as any other relevant equitable considerations. The relative benefits received by the Selling Stockholders on the one hand and the Underwriters on the other hand in connection with the offering of the Shares shall be deemed to be in the same respective proportions as, for each Selling Stockholder, the net proceeds from the offering of the Shares (before deducting expenses) received by such Selling Stockholder and the total underwriting discounts and commissions received by the Underwriters, in each case as set forth in the table on the cover of the Prospectus, bear to the aggregate Public Offering Price of the Shares. The relative fault of the indemnifying party or parties on the one hand and the indemnified party or parties on the other hand shall be determined by reference to, among other things, whether the untrue or alleged untrue statement of a material fact or the omission or alleged omission to state a material fact relates to information supplied by the Maravai Parties, by the Selling Stockholders or by the Underwriters and the parties’ relative intent, knowledge, access to information and opportunity to correct or prevent such statement or omission. The Underwriters’ respective obligations to contribute pursuant to this Section 9 are several in proportion to the respective number of Shares they have purchased hereunder, and not joint.

(e) Each of the Maravai Parties, the Selling Stockholders and the Underwriters agree that it would not be just or equitable if contribution pursuant to this Section 10 were determined by pro rata allocation (even if the Underwriters were treated as one entity for such purpose) or by any other method of allocation that does not take account of the equitable considerations referred to in Section 10(d). The amount paid or payable by an indemnified party as a result of the losses, claims, damages and liabilities referred to in Section 10(d) shall be deemed to include, subject to the limitations set forth above, any legal or other expenses reasonably incurred by such indemnified party in connection with investigating or defending any such action or claim. Notwithstanding the provisions of this Section 10, no Underwriter shall be required to contribute any amount in excess of the amount by which the total price at which the Shares underwritten by it and distributed to the public were offered to the public exceeds the amount of any damages that such Underwriter has otherwise been required to pay by reason of such untrue or alleged untrue statement or omission or alleged omission. No person guilty of fraudulent misrepresentation (within the meaning of Section 11(f) of the Securities Act) shall be entitled to contribution from any person who was not guilty of such fraudulent misrepresentation. The remedies provided for in this Section 10 are not exclusive and shall not limit any rights or remedies which may otherwise be available to any indemnified party at law or in equity.

(f) The indemnity and contribution provisions contained in this Section 9 and the representations, warranties and other statements of the Maravai Parties and the Selling Stockholders contained in this Agreement shall remain operative and in full force and effect regardless of (i) any termination of this

Agreement, (ii) any investigation made by or on behalf of any Underwriter, the directors, officers, employees and agents of each Underwriter, any person controlling any Underwriter or any affiliate of any Underwriter, any Selling Stockholder or any person controlling any Selling Stockholder, or by or on behalf of the Maravai Parties, their officers or directors or any person controlling the Maravai Parties and (iii) acceptance of and payment for any of the Shares.

(g) The liability of each Selling Stockholder under the indemnity and contribution agreements hereunder shall not exceed the aggregate gross proceeds after underwriting commissions and discounts, but before expenses, to such Selling Stockholder from the sale of the Shares sold by such Selling Stockholder pursuant to this Agreement. The Selling Stockholders shall be liable only to the extent that the relevant loss, claim, damage or liability arises out of or is based upon an untrue statement or alleged untrue statement or omission or alleged omission, in each case, which relates to the Selling Stockholder made in the Registration Statement, the Time of Sale Prospectus or the Prospectus and in conformity with any Selling Stockholder Information furnished to the Underwriters in writing by the Selling Stockholder expressly for use therein. The Selling Stockholders obligations in this Section 10 to indemnify and to contribute are several and not joint.

11. Termination. The Underwriters may terminate this Agreement by notice given by the Representatives to the Company, if after the execution and delivery of this Agreement and prior to or on the Closing Date or any Option Closing Date, as the case may be, (i) trading generally shall have been suspended or materially limited on, or by, as the case may be, any of the New York Stock Exchange, the NYSE American, the Nasdaq Global Select Market, the Nasdaq Global Market, the Chicago Board of Options Exchange, the Chicago Mercantile Exchange or the Chicago Board of Trade, (ii) trading of any securities of the Company shall have been suspended on any exchange or in any over-the-counter market, (iii) a material disruption in securities settlement, payment or clearance services in the United States shall have occurred, (iv) any moratorium on commercial banking activities shall have been declared by Federal or New York State authorities or (v) there shall have occurred any outbreak or escalation of hostilities, or any change in financial markets or any calamity or crisis that, in the Representatives’ judgment, is material and adverse and which, singly or together with any other event specified in this clause (v), makes it, in the Representatives’ judgment, impracticable or inadvisable to proceed with the offer, sale or delivery of the Shares on the terms and in the manner contemplated in the Time of Sale Prospectus or the Prospectus.

12. Effectiveness; Defaulting Underwriters. This Agreement shall become effective upon the execution and delivery hereof by the parties hereto.

If, on the Closing Date or an Option Closing Date, as the case may be, any one or more of the Underwriters shall fail or refuse to purchase Shares that it has or they have agreed to purchase hereunder on such date, and the aggregate number of Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase is not more than one-tenth of the aggregate number of the Shares to be purchased on such

date, the other Underwriters shall be obligated severally in the proportions that the number of Firm Shares set forth opposite their respective names in Schedule II bears to the aggregate number of Firm Shares set forth opposite the names of all such non-defaulting Underwriters, or in such other proportions as the Representatives may specify, to purchase the Shares which such defaulting Underwriter or Underwriters agreed but failed or refused to purchase on such date; provided that in no event shall the number of Shares that any Underwriter has agreed to purchase pursuant to this Agreement be increased pursuant to this Section 12 by an amount in excess of one-ninth of such number of Shares without the written consent of such Underwriter. If, on the Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Firm Shares and the aggregate number of Firm Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Firm Shares to be purchased on such date, and arrangements satisfactory to the Representatives, the Company and the Selling Stockholders for the purchase of such Firm Shares are not made within 36 hours after such default, this Agreement shall terminate without liability on the part of any non-defaulting Underwriter, the Company or the Selling Stockholders. In any such case either the Representatives, the Company or the relevant Selling Stockholders shall have the right to postpone the Closing Date, but in no event for longer than seven days, in order that the required changes, if any, in the Registration Statement, in the Time of Sale Prospectus, in the Prospectus or in any other documents or arrangements may be effected. If, on an Option Closing Date, any Underwriter or Underwriters shall fail or refuse to purchase Additional Shares and the aggregate number of Additional Shares with respect to which such default occurs is more than one-tenth of the aggregate number of Additional Shares to be purchased on such Option Closing Date, the non-defaulting Underwriters shall have the option to (i) terminate their obligation hereunder to purchase the Additional Shares to be sold on such Option Closing Date or (ii) purchase not less than the number of Additional Shares that such non-defaulting Underwriters would have been obligated to purchase in the absence of such default. Any action taken under this paragraph shall not relieve any defaulting Underwriter from liability in respect of any default of such Underwriter under this Agreement.

If this Agreement shall be terminated by the Underwriters, or any of them, because of any failure or refusal on the part of the Maravai Parties or any Selling Stockholder to comply with the terms or to fulfill any of the conditions of this Agreement, or if for any reason the Maravai Parties or any Selling Stockholder shall be unable to perform its obligations under this Agreement, the Maravai Parties and the Selling Stockholders will reimburse the Underwriters or such Underwriters as have so terminated this Agreement with respect to themselves, severally, for all out-of-pocket expenses (including the fees and disbursements of their counsel) reasonably incurred and documented by such Underwriters in connection with this Agreement or the offering contemplated hereunder.

13. Entire Agreement. (a) This Agreement, together with any contemporaneous written agreements and any prior written agreements (to the extent not superseded by this Agreement) that relate to the offering of the Shares, represents the entire agreement between the Maravai Parties and the Selling Stockholders, on the one hand, and the Underwriters, on the other, with respect to the preparation of any preliminary prospectus, the Time of Sale Prospectus, the Prospectus, the conduct of the offering, and the purchase and sale of the Shares.

(b) The Maravai Parties and each Selling Stockholder acknowledge that in connection with the offering of the Shares: (i) the Underwriters have acted at arm’s length, are not agents of, and owe no fiduciary duties to, the Maravai Parties, such Selling Stockholder or any other person, (ii) the Underwriters owe the Maravai Parties and such Selling Stockholder only those duties and obligations set forth in this Agreement, any contemporaneous written agreements and prior written agreements (to the extent not superseded by this Agreement), if any, (iii) the Underwriters may have interests that differ from those of the Maravai Parties and such Selling Stockholder, and (iv) none of the activities of the Underwriters in connection with the transactions contemplated herein constitutes a recommendation, investment advice, or solicitation of any action by the Underwriters with respect to any entity or natural person. The Maravai Parties and each Selling Stockholder waive to the full extent permitted by applicable law any claims either of them may have against the Underwriters arising from an alleged breach of fiduciary duty in connection with the offering of the Shares.

(c) Each Selling Stockholder further acknowledges and agrees that, although the Underwriters may provide such Selling Stockholder with certain Regulation Best Interest and Form CRS disclosures or other related documentation in connection with the offering, the Underwriters are not making a recommendation to such Selling Stockholder to participate in the offering or sell any Shares at the Purchase Price, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.

14. Recognition of the U.S. Special Resolution Regimes. (a) In the event that any Underwriter that is a Covered Entity becomes subject to a proceeding under a U.S. Special Resolution Regime, the transfer from such Underwriter of this Agreement, and any interest and obligation in or under this Agreement, will be effective to the same extent as the transfer would be effective under the U.S. Special Resolution Regime if this Agreement, and any such interest and obligation, were governed by the laws of the United States or a state of the United States.

(b) In the event that any Underwriter that is a Covered Entity or a BHC Act Affiliate of such Underwriter becomes subject to a proceeding under a U.S. Special Resolution Regime, Default Rights under this Agreement that may be exercised against such Underwriter are permitted to be exercised to no greater extent than such Default Rights could be exercised under the U.S. Special Resolution Regime if this Agreement were governed by the laws of the United States or a state of the United States.

For purposes of this Section a “BHC Act Affiliate” has the meaning assigned to the term “affiliate” in, and shall be interpreted in accordance with, 12 U.S.C. § 1841(k). “Covered Entity” means any of the following: (i) a “covered entity” as that term is

15. Counterparts. This Agreement may be signed in two or more counterparts, each of which shall be an original, with the same effect as if the signatures thereto and hereto were upon the same instrument. Counterparts may be delivered via facsimile, electronic mail (including any electronic signature covered by the U.S. federal ESIGN Act of 2000, Uniform Electronic Transactions Act, the Electronic Signatures and Records Act or other applicable law, e.g., www.docusign.com) or other transmission method and any counterpart so delivered shall be deemed to have been duly and validly delivered and be valid and effective for all purposes.

16. Applicable Law.

The Maravai Parties irrevocably submit to the non-exclusive jurisdiction of any New York State or United States Federal court sitting in The City of New York over any suit, action or proceeding arising out of or relating to this Agreement, the Time of Sale Prospectus, the Prospectus, the Registration Statement or the offering of the Shares (each, a “Related Proceeding”). The Maravai Parties irrevocably waive, to the fullest extent permitted by law, any objection which it may now or hereafter have to the laying of venue of any Related Proceeding brought in such a court and any claim that any such Related Proceeding brought in such a court has been brought in an inconvenient forum. To the extent that the Maravai Parties have or hereafter may acquire any immunity (on the grounds of sovereignty or otherwise) from the jurisdiction of any court or from any legal process with respect to itself or its property, the Maravai Parties irrevocably waive, to the fullest extent permitted by law, such immunity in respect of any such suit, action or proceeding.

Ladies and Gentlemen:

The undersigned understands that Morgan Stanley & Co. LLC, Jefferies LLC and Goldman Sachs & Co. LLC (the “Representatives”) propose to enter into an Underwriting Agreement (the “Underwriting Agreement”) with Maravai LifeSciences Holdings, Inc., a Delaware corporation (the “Company”) and certain shareholders of the Company named in Schedule I thereto, providing for the public offering (the “Public Offering”) by the several Underwriters, including the Representatives (the “Underwriters”), of shares (the “Shares”) of the Class A common stock, par value $0.01 per share, of the Company (the “Class A Common Stock”). As used herein, the term “Common Stock” refers to shares of the Company’s Class A Common Stock and Class B common stock, par value $0.01 per share.

To induce the Underwriters that may participate in the Public Offering to continue their efforts in connection with the Public Offering, the undersigned hereby agrees that, without the prior written consent of at least two of the Representatives (provided that each Representative shall have been informed of and given a reasonable opportunity to give or withhold consent to any such waiver request) (such consent and notice, the “Requisite Consent”) on behalf of the Underwriters, it will not, and will not publicly disclose an intention to or cause any of its affiliates to, during the period commencing on the date hereof and ending 60 days after the date of the final prospectus relating to the Public Offering (the “Prospectus”) (such period, the “Restricted Period”), (1) offer, pledge, sell, contract to sell, sell any option or contract to purchase, purchase any option

A-1

or contract to sell, grant any option, right or warrant to purchase, lend, or otherwise transfer or dispose of, directly or indirectly, any shares of Common Stock beneficially owned (as such term is used in Rule 13d-3 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”)), by the undersigned or any other securities so owned convertible into or exercisable or exchangeable for Common Stock (collectively, “Lock-Up Securities”), including units of Maravai Topco Holdings, LLC (the “Units”) or (2) enter into any swap or other arrangement that transfers to another, in whole or in part, any of the economic consequences of ownership of the Lock-Up Securities, whether any such transaction described in clause (1) or (2) above is to be settled by delivery of Common Stock or such other Lock-Up Securities, in cash or otherwise. The undersigned acknowledges and agrees that the foregoing precludes the undersigned from engaging in any hedging or other transactions designed or intended, or which could reasonably be expected to lead to or result in, a sale or disposition of any Lock-Up Securities, even if any such sale or disposition transaction or transactions would be made or executed by or on behalf of someone other than the undersigned. The foregoing restrictions shall not apply to (a) transactions relating to shares of Class A Common Stock acquired in open market transactions after the completion of the Public Offering, provided that no filing under Section 16(a) of the Exchange Act shall be required or shall be voluntarily made in connection with subsequent sales of Class A Common Stock in such open market transactions; (b) transfers of Lock-Up Securities (i) as a bona fide gift or gifts, (ii) to any immediate family member of the undersigned, or any of its affiliates, or any trust for the direct or indirect benefit of the undersigned, or any of its affiliates (for the purposes of this agreement, “immediate family” shall mean any relationship by blood, marriage or adoption, not more remote than first cousin), (iii) to a corporation, partnership, limited liability company, trust or other entity of which the undersigned, or any of its affiliates, and the immediate family of the undersigned are the legal and beneficial owner of all of the outstanding equity securities or similar interests, or (iv) to a nominee or custodian of a person or entity to whom a disposition or transfer would be permissible under clauses (i) through (iii) above; (c) distributions of Lock-Up Securities to (i) a partner, member or stockholder, as the case may be, of such partnership, limited liability company or corporation, (ii) any wholly-owned subsidiary of the undersigned, (iii) an affiliate (as such term is defined in Rule 405 of the Securities Act of 1933, as amended) of the undersigned or (iv) if a transferee referred to in clauses (i) through (iii) above is not a natural person, any direct or indirect partner, member or shareholder of such transferee until the Lock-Up Securities come to be held by a natural person; provided that in the case of any transfer pursuant to clause (b)(i), (i) each donee or transferee shall sign and deliver a lock-up agreement substantially in the form of this agreement and (ii) no filing under Section 16(a) of the Exchange Act, reporting a reduction in beneficial ownership of shares of Common Stock, shall be required or shall be voluntarily made during the Restricted Period (other than a filing on a Form 5 that shall clearly indicate in the footnotes thereto the nature and conditions of such transfer, that such transfer is not for value and that the Lock-Up Securities subject to such transfer remain subject to restrictions set forth herein), provided further that in the case of any transfer or distribution pursuant to clause (b)(ii), (b)(iii), or (c), (i) each transferee or distributee shall sign and deliver a lock-up agreement substantially in the form of this agreement; provided that with respect to any related series of transfers or distributions to transferees or distributees otherwise permitted under

A-2

such clauses that are deemed to occur simultaneously, only the ultimate transferee or distributee in such series shall be required to sign and deliver such a lock-up agreement, and (ii) if the undersigned is required to file a report under Section 16(a) of the Exchange Act reporting such transfer during the Restricted Period, the undersigned shall clearly indicate in the footnotes thereto the nature and conditions of such transfer, that such transfer is not for value and that the Lock-Up Securities subject to such transfer remain subject to restrictions set forth herein; (d) the establishment of a trading plan on behalf of the undersigned pursuant to Rule 10b5-1 under the Exchange Act for the transfer of shares of Class A Common Stock, provided that (i) such plan does not provide for the transfer of Class A Common Stock during the Restricted Period and (ii) to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the establishment of such plan, such announcement or filing shall include a statement to the effect that no transfer of Class A Common Stock may be made under such plan during the Restricted Period; (e) a transfer of Lock-Up Securities pursuant to a bona fide third party tender offer, merger, consolidation or other similar transaction or transactions made to all or substantially all holders of the Company’s Common Stock and approved by the board of directors of the Company the result of which is that any “person” or “group” (within the meaning of Section 13(d) of the Exchange Act), shall or would become, after giving effect to such transaction or transactions, the beneficial owner (as defined in Rules 13d-3 and 13d-5 of the Exchange Act) of more than 50% of the total voting power of the voting securities of the Company), provided that in the event that such tender offer, merger, consolidation or other such transaction or transactions shall not be completed, the undersigned’s Lock-Up Securities shall remain subject to the provisions of this agreement during the Restricted Period; (f)(i) as a result of the operation of law, or pursuant to an order of a court (including a domestic order, divorce settlement, divorce decree or separation agreement) or regulatory agency or (ii) by will, other testamentary document or intestate succession, provided that no filing by the undersigned or any party (transferor or transferee) under the Exchange Act, or other public announcement, shall be required or shall be voluntarily made in connection with any such transfer during the Restricted Period (other than a filing on a Form 5 that shall disclose that such transfer was a result of the operation of law, or pursuant to an order of a court or regulatory agency or by will, other testamentary document or intestate succession); (g) the repurchase of Lock-Up Securities by the Company pursuant to equity award agreements or other contractual arrangements providing for the right of said repurchase in connection with the termination of the undersigned’s employment or service with the Company, provided that no filing by the undersigned under the Exchange Act, or other public announcement, shall be voluntarily made in connection with any such transfer, and if the undersigned is required to file a report under the Exchange Act related thereto during the Restricted Period, such report shall disclose that such transfer was a result of the repurchase of the Lock-Up Securities or such other securities by the Company pursuant to equity award agreements or other contractual arrangements in connection with the termination of the undersigned’s employment or service with the Company; (h) pursuant to the exercise of an option to purchase Lock-Up Securities in connection with the termination or expiration of such option pursuant to its terms, provided that (1) such option was granted pursuant to a Company stock option plan or other equity incentive plan described in the

A-3

registration statement on Form S-1 related to the Public Offering and the Prospectus, (2) any Lock-Up Securities received upon such exercise shall be subject to the terms of this agreement and (3) no filing by the undersigned or any party (transferor or transferee) under the Exchange Act, or other public announcement shall be voluntarily made in connection with any such transfer, and if the holder is required to file a report under the Exchange Act related thereto during the restricted period, such report shall disclose that such transfer was a result of the exercise of options expiring or terminating in accordance with their terms and does not result in any aggregate reduction in the beneficial ownership; (i) to the Company (x) pursuant to the exercise, on a “cashless” or “net exercise” basis, of any option to purchase Lock-Up Securities granted by the Company pursuant to stock option or equity incentive plans described in the Prospectus, or (y) for the purpose of satisfying any withholding taxes (including estimated taxes) due as a result of the exercise of any option to purchase Lock-Up Securities or the vesting of any equity awards granted by the Company pursuant to stock option or equity incentive plans described in the Prospectus, provided that no filing by the undersigned or any party (transferor or transferee) under the Exchange Act, or other public announcement, shall be voluntarily made in connection with any such transfer, and if the undersigned is required to file a report under the Exchange Act related thereto during the Restricted Period, such report shall disclose that such transfer was a result of the exercise, on a “cashless” or “net exercise” basis, of any option to purchase Lock-Up Securities granted by the Company pursuant to stock option or equity incentive plans described in the Prospectus, or for the purpose of satisfying any withholding taxes (including estimated taxes) due as a result of the exercise of any option to purchase Securities or the vesting of any equity awards granted by the Company pursuant to stock option or equity incentive plans described in the Prospectus; (j) in any exchange of Units and a corresponding number of shares of the Company’s Class B common stock into or for shares of Class A Common Stock (or securities convertible into or exercisable or exchangeable for Class A Common Stock) in a manner consistent with the provisions therefor set forth in the Prospectus; provided that to the extent a public announcement or filing under the Exchange Act, if any, is required of or voluntarily made by or on behalf of the undersigned or the Company regarding the exchange, such announcement or filing shall include a statement to the effect that such exchange occurred pursuant to the exchange agreement by and among the Company, Maravai Topco Holdings, LLC and Maravai Life Sciences Holdings, LLC, and no transfer of the shares of Class A Common Stock or other securities received upon exchange may be made during the Restricted Period; (k) any pledge, hypothecation or other grant of a security interest in any Lock-Up Securities to one or more lending institutions as collateral or security for any loan, advance or extension of credit and the transfer of such Lock-Up Securities to such lending institution upon foreclosure of such Lock-Up Securities; provided that no subsequent transfer or sale of Lock-Up Securities by such lending institution shall be made during the Restricted Period; and (l) the sale of any shares of Class A common stock to the Underwriters pursuant to the Public Offering. In addition, the undersigned agrees that, without the Requisite Consent of the Representatives on behalf of the Underwriters, it will not, during the Restricted Period, make any demand for or exercise any right with respect to, the registration of any shares of Common Stock, Units or any other security convertible into or exercisable or exchangeable for Common Stock, provided that, for the avoidance of doubt, to the extent

A-4

the undersigned has demand and/or piggyback registration rights, the foregoing shall not prohibit the undersigned from notifying the Company privately that it is or will be exercising its demand and/or piggyback registration rights following the expiration of the Restricted Period and undertaking preparations related thereto. The undersigned also agrees and consents to the entry of stop transfer instructions with the Company’s transfer agent and registrar against the transfer of the undersigned’s Lock-Up Securities except in compliance with the foregoing restrictions.

The undersigned understands that the Company and the Underwriters are relying upon this agreement in proceeding toward consummation of the Public Offering. The undersigned further understands that this agreement is irrevocable and shall be binding upon the undersigned’s heirs, legal Representatives, successors and assigns.

The undersigned acknowledges and agrees that the Underwriters have not provided any recommendation or investment advice nor have the Underwriters solicited any action from the undersigned with respect to the Public Offering of the Shares and the undersigned has consulted their own legal, accounting, financial, regulatory and tax advisors to the extent deemed appropriate. The undersigned further acknowledges and agrees that, although the Underwriters may provide certain Regulation Best Interest and Form CRS disclosures or other related documentation to you in connection with the Public Offering, the Underwriters are not making a recommendation to you to participate in the Public Offering or sell any Shares at the price determined in the Public Offering, and nothing set forth in such disclosures or documentation is intended to suggest that any Underwriter is making such a recommendation.

The undersigned hereby consents to receipt of this agreement in electronic form and understands and agrees that this agreement may be signed electronically. In the event that any signature is delivered by facsimile transmission, electronic mail, or otherwise by electronic transmission evidencing an intent to sign this agreement, such facsimile transmission, electronic mail or other electronic transmission shall create a valid and binding obligation of the undersigned with the same force and effect as if such signature were an original. Execution and delivery of this agreement by facsimile transmission, electronic mail or other electronic transmission is legal, valid and binding for all purposes.

Whether or not the Public Offering actually occurs depends on a number of factors, including market conditions. Any Public Offering will only be made pursuant to an Underwriting Agreement, the terms of which are subject to negotiation between the Company and the Underwriters.

This agreement shall automatically terminate and be of no further effect upon the earliest to occur, if any, of: (i) the date of filing with the SEC of a notice of withdrawal of the registration statement on Form S-1 related to the Public Offering pursuant to Rule 477 promulgated under the Securities Act of 1933, as amended, prior to its effectiveness, (ii) the date that the Company advises the Representatives in writing prior to the execution of the Underwriting Agreement that it has determined not to proceed with the Public Offering, (iii) the date that the Underwriting Agreement (other than the provisions thereof that survive termination) terminates or is terminated prior to payment for and delivery of any Shares to be sold thereunder, and (iv) October 31, 2021, in the event that the Underwriting Agreement has not been executed on or before that date.

A-5

This agreement and any claim, controversy or dispute arising under or related to this agreement shall be governed by and construed in accordance with the laws of the State of New York.
