Performance Stock Unit Award Agreement under 2017 Incentive Award Plan

Pursuant to the Performance Stock Unit Award Grant Notice (the “Grant Notice”) to which this Performance Stock Unit Award Agreement (this “Agreement”) is attached, Bio-Rad Laboratories, Inc., a Delaware corporation (the “Company”), has granted to Holder the right to receive the number of Performance Stock Units (the “PSUs”) under the 2017 Incentive Award Plan, as amended from time to time (the “Plan”), as set forth in the Grant Notice.

All capitalized terms used in this Agreement without definition shall have the meanings ascribed in the Plan and the Grant Notice.

The PSUs are subject to the terms and conditions of the Plan, which are incorporated herein by reference. In the event of any inconsistency between the Plan and this Agreement, the terms of the Plan shall control.

1.Grant and Vesting of the PSUs. As set forth in the Grant Notice, the Company hereby grants Holder PSUs, subject to all the terms and conditions in this Agreement, the Country Addenda, the Grant Notice and the Plan. The PSUs shall vest as set forth on the Grant Notice under “Vesting and Settlement”. Unless the Achievement Factor (as defined in Exhibit B) is greater than zero and unless and until the PSUs have vested in the manner set forth in this Agreement, the Holder will have no right to receive Shares under any such PSUs. No Shares shall be issued to Holder until the time set forth in Section 2 below. Prior to the actual issuance of any Shares, such PSUs will represent an unsecured obligation of the Company, payable only from the general assets of the Company. Only whole Shares shall be issued upon vesting of the PSUs, and the Company shall be under no obligation to issue any fractional Shares to Holder.

2.Issuance of Shares. Shares shall be issued to Holder on or as soon as administratively practicable following each Determination Date as set forth in Exhibit B (the “Vesting Date”) (and in no event later than the earlier of 90 days following the Vesting Date or 2 1/2 months following the end of the calendar year in which such Vesting Date or vesting event occurs). After each Vesting Date the Company shall promptly cause to be issued (either in book-entry form or otherwise) to Holder or Holder’s beneficiaries, as the case may be, Shares with respect to PSUs that became vested on such Vesting Date.

3.Acceleration of Vesting. Notwithstanding Section 1 above, pursuant to Section 13.2(d) of the Plan, in the event of a Change in Control that occurs prior to March 31, 2025, the PSUs shall become fully vested upon the Change in Control based on an Achievement Factor of one (1.0), or if determinable and greater than (1.0), the actual Achievement Factor determined in accordance with Exhibit B.

4.Taxes.

(a)Regardless of any action the Company, or, if different, Holder’s employer (the “Employer”) takes with respect to any or all income tax, social insurance, payroll tax, fringe benefits tax, payment on account or other tax-related items related to Holder’s participation in the Plan and legally applicable to Holder (“Tax-Related Items”), Holder acknowledges and agrees that the ultimate liability for all Tax-Related Items is and remains Holder’s responsibility and may exceed the amount actually withheld by the Company or the Employer. Holder further acknowledges that the Company and/or the Employer (i) make no representations or undertakings regarding the treatment of any Tax-Related Items in connection with any aspect of the PSUs, including, but not limited to, the grant, vesting or settlement of the PSUs, the issuance of Shares upon settlement of the PSUs, the subsequent sale of Shares acquired under the Plan and the receipt of dividends or Dividend Equivalents, if any; and (ii) do not commit to and are under no obligation to structure the terms of the PSUs or any aspect of the PSUs to reduce or eliminate Holder’s liability for Tax-Related Items or achieve any particular tax result. Further, if Holder is subject to Tax-Related Items in more than one jurisdiction, Holder acknowledges that the Company

and/or the Employer (or former employer, as applicable) may be required to withhold or account for Tax-Related Items in more than one jurisdiction.

(b)Prior to any relevant taxable or tax withholding event, as applicable, Holder agrees to make adequate arrangements satisfactory to the Company and/or the Employer to satisfy any withholding obligation for Tax-Related Items. In this regard, except as set forth in any separate 10b5-1 plan entered into by Holder and approved by the Company, Holder authorizes the Company and/or the Employer, or their respective agents, at their discretion, to satisfy the withholding obligation for Tax-Related Items by one or any combination of the following:

(i)requiring Holder to pay an amount the Company determines to be an appropriate amount to satisfy the Tax-Related Items directly to the Company and/or the Employer in the form of cash, check or other cash equivalent;

(ii)withholding from proceeds of the sale of a number of Shares acquired upon settlement of the PSUs that the Company determines to be appropriate to generate cash proceeds sufficient to satisfy the withholding obligations for Tax-Related Items either through a voluntary sale or through a mandatory sale arranged by the Company (on Holder’s behalf pursuant to this authorization), provided that Holder will be responsible for all brokerage fees and other costs of the sale and agrees to indemnify and hold the Company harmless from any losses, costs, damages, or expenses related to any such sale and that no fractional Shares will be sold to cover the Tax-Related Items;

(iii)deducting an amount the Company determines to be an appropriate amount to satisfy the Tax-Related Items from wages or other cash compensation payable to Holder by the Company and/or the Employer;

(iv)    withholding a number of vested whole Shares subject to the PSUs otherwise issuable to Holder that have a Fair Market Value equal to the amount the Company determines to be an appropriate amount to satisfy the withholding obligations for Tax-Related Items; and/or

(v) any other method of withholding determined by the Company and, to the extent required by Applicable Law or the Plan, approved by the Committee.

(c)Notwithstanding anything to the contrary in this Section 4, if Holder is an officer of the Company within the meaning of Section 16 of the Exchange Act, the Board or Committee (as constituted to satisfy Rule 16b-3 of the Exchange Act) will determine which, if any, of the withholding methods set out in Section 4(b) will be used.

(d) In determining the appropriate amount to satisfy any withholding obligation for Tax-Related Items, the Company may refer to minimum statutory withholding rates or other applicable withholding rates, including up to the maximum statutory tax rate for the tax jurisdiction(s) applicable to Holder, provided that Holder may be required to pay Tax-Related Items in the event that a minimum statutory withholding rate is used or Holder may receive a refund in cash of any amount that was over-withheld based on a rate that exceeds Holder’s actual tax rate and, in this case, Holder will have no entitlement to the Class A common stock equivalent.

(e)If the obligation for Tax-Related Items is satisfied by withholding a number of whole Shares as described in Section 4(b)(iv) above, for tax purposes, Holder is deemed to have been issued the full number of Shares subject to the vested PSUs, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items.

(f)The Company shall not be obligated to deliver any new certificate representing Shares issuable (or other indicia of Share ownership) with respect to the PSUs to Holder or Holder’s legal representative unless and until Holder or Holder’s legal representative shall have paid or otherwise satisfied in full the amount of all Tax-Related Items.

(g)This Agreement, the PSUs and payments made pursuant to this Agreement are intended to comply with or qualify for an exemption from Section 409A of the Code and the Treasury

Regulations thereunder (“Section 409A”) and shall be interpreted in a manner consistent with that intention. Notwithstanding any other provision of this Agreement, the Company reserves the right, to the extent the Company deems necessary or advisable, in its sole discretion, to unilaterally amend the Plan and/or this Agreement to ensure that all PSUs are awarded in a manner that qualifies for exemption from or complies with Section 409A. This Section 4(g) does not create an obligation on the part of the Company to modify the terms of this Agreement or the Plan or to mitigate any additional tax, interest and/or penalties or other adverse tax consequences that may apply under Code Section 409A if compliance is not practical and does not guarantee that the PSUs or the delivery of Shares upon vesting/settlement of the PSUs will not be subject to taxes, interest and penalties or any other adverse tax consequences under Section 409A of the Code. The Company will have no liability to the Holder or any other party if the PSU that is intended to be exempt from, or compliant with, Section 409A of the Code, is not so exempt or compliant or for any action taken by the Administrator with respect thereto.

5.Award Not Transferable. This grant of PSUs and the rights and privileges conferred hereby will not be transferred, assigned, pledged or hypothecated in any way (whether by operation of law or otherwise) and will not be subject to sale under execution, attachment or similar process. Upon any attempt to transfer, assign, pledge, hypothecate or otherwise dispose of this grant, or any right or privilege conferred hereby, or upon any attempted sale under any execution, attachment or similar process, this grant and the rights and privileges conferred hereby immediately will become null and void.

6.Rights as Stockholder. Neither Holder nor any person claiming under or through Holder will have any of the rights or privileges of a stockholder of the Company with respect to any Shares deliverable hereunder unless and until certificates representing such Shares (which may be in book entry form) will have been issued and recorded on the records of the Company or its transfer agents or registrars, and delivered to Holder (including through electronic delivery to a brokerage account). After such issuance, recordation and delivery, Holder will have all the rights of a stockholder of the Company with respect to voting such Shares and receipt of dividends and distributions on such Shares.

7.Conditions to Issuance of Certificates. Notwithstanding any other provision of this Agreement, unless there is an available exemption from any registration, qualification or other legal requirement applicable to the Shares, the Company shall not be required to issue or deliver any certificate or certificates for any Shares prior to the fulfillment of all of the following conditions: (a) the admission of the Shares to listing on all stock exchanges on which such Shares are then listed, (b) the completion of any registration or other qualification of the Shares under any state, federal, or local law or under rulings or regulations of the U.S. Securities and Exchange Commission (“SEC”) or other governmental regulatory body, which the Company shall, in its sole and absolute discretion, deem necessary and advisable, (c) the obtaining of any approval or other clearance from any governmental agency that the Company shall, in its absolute discretion, determine to be necessary or advisable, and (d) the lapse of any such reasonable period of time following the date the PSUs vest as the Company may from time to time establish for reasons of administrative convenience. Holder understands that the Company is under no obligation to register or qualify the Shares with the SEC or any state or foreign securities commission or to seek approval or clearance from any governmental authority for the issuance or sale of the Shares. Further, Holder agrees that the Company shall have unilateral authority to amend the Plan and this Agreement without Holder’s consent to the extent necessary to facilitate compliance with securities or other laws applicable to the issuance of Shares.

8.Not a Contract of Employment. Nothing in this Agreement or in the Plan, or Holder’s participation in the Plan, shall confer upon Holder any right to continue to serve as an Employee or other service provider of the Company, any Subsidiary or the Employer and shall not interfere with the ability of the Company, any Subsidiary or the Employer to terminate Holder’s employment or service relationship at any time. Further, the grant of PSUs and Holder’s participation in the Plan will not be interpreted to form or amend an employment contract or relationship with the Company or any Subsidiary.

9.Nature of Grant. In accepting the PSUs, Holder acknowledges, understands and agrees that:

(a)the Plan is established voluntarily by the Company, it is discretionary in nature and it may be modified, amended, suspended or terminated by the Company at any time to the extent permitted by the Plan;

(b)the grant of the PSUs is exceptional, voluntary and occasional and does not create any contractual or other right to receive future grants of PSUs, or benefits in lieu of PSUs even if PSUs have been granted in the past;

(c)all decisions with respect to future awards of PSUs, if any, will be at the sole discretion of the Company;

(d)Holder’s participation in the Plan is voluntary;

(e)the PSUs and the Shares subject to the PSUs, and the income and value of same, are not intended to replace any pension rights or compensation;

(h)the future value of the underlying Shares is unknown, indeterminable and cannot be predicted with certainty;

(i)no claim or entitlement to compensation or damages shall arise from forfeiture of the PSUs resulting from termination of Holder’s employment relationship (for any reason whatsoever and whether or not later found to be invalid or in breach of employment laws in the jurisdiction where Holder is employed or the terms of Holder’s employment agreement, if any);

(j)for purposes of the PSUs, Holder's employment will be considered terminated as of the date Holder is no longer actively providing services as an employee to the Company, the Employer or any other Subsidiary of the Company (regardless of the reason for the termination and whether or not such termination is later to be found invalid or in breach of employment laws in the jurisdiction where Holder is employed or the terms of Holder’s employment agreement, if any), and unless otherwise expressly provided in this Agreement or determined by the Company, Holder’s right to vest in the PSUs under the Plan, if any, will terminate as of such date and will not be extended by any notice period (e.g., Holder's period of active service would not include any contractual notice period or any period of “garden leave” or similar period mandated under employment laws in the jurisdiction where Holder is employed or the terms of Holder’s employment, if any) and Holder will not earn or be entitled to any pro-rated vesting for that portion of time before the date on which Holder’s right to vest terminates (as determined under this provision) nor will Holder be entitled to any compensation for lost vesting; the Company shall have the exclusive discretion to determine when Holder is no longer actively providing services as an employee for purposes of the PSU Award while on a leave of absence;

(k)unless otherwise provided in the Plan or by the Company in its discretion, the PSUs and the benefits evidenced by this Agreement do not create any entitlement to have the PSUs or any such benefits transferred to, or assumed by, another company nor be exchanged, cashed-out or substituted for, in connection with any corporate transaction affecting the shares of the Company; and

(l)neither the Company, the Employer nor any Subsidiary shall be liable for any foreign exchange rate fluctuation between Holder’s local currency and the United States Dollar that may affect the value of the PSUs or of any amounts due to Holder pursuant to the settlement of the PSUs or the subsequent sale of any Shares acquired upon settlement.

10.No Advice Regarding Grant. The Company is not providing any tax, legal or financial advice, nor is the Company making any recommendations regarding Holder’s participation in the Plan, or Holder’s acquisition or sale of the underlying Shares.

22.Waiver. Holder acknowledges that a waiver by the Company of breach of any provision of the Agreement shall not operate or be construed as a waiver of any other provision of this Agreement, or of any subsequent breach by Holder or any other Holder.

23.Insider Trading/Market Abuse Laws. Holder acknowledges that he or she may be subject to insider trading restrictions and/or market abuse laws based on the exchange (if any) on which Shares are listed, and in applicable jurisdictions, including but not limited to the United States, Holder’s country and the designated broker’s country, which may affect Holder’s ability to accept, acquire, sell or otherwise dispose of Shares, rights to Shares (e.g., RSUs) or rights linked to the value of Shares under the Plan during such times as Holder is considered to have “inside information” regarding the Company (as defined by the laws in applicable jurisdictions). Local insider trading laws and regulations may prohibit the cancellation or amendment of orders Holder placed before he or she possessed inside information. Further, Holder could be prohibited from (i) disclosing the inside information to any third party, which may include fellow employees and (ii) “tipping” third parties or causing them otherwise to buy or sell securities. Any restrictions under these laws or regulations are separate from and in addition to any restrictions that may be imposed under any applicable Company insider trading policy. Holder acknowledges he or she is responsible for complying with any applicable restrictions and is encouraged to speak to his or her personal legal advisor for further details regarding any applicable insider trading and/or market abuse laws in Holder’s country.

24.Foreign Asset / Account Reporting Requirements, Exchange Controls and Tax Requirements. Holder acknowledges that his or her country may have certain foreign asset and/or account reporting requirements and exchange controls which may affect his or her ability to acquire or hold Shares under the Plan or cash received from participating in the Plan (including from any dividends or Dividend Equivalents received or sale proceeds arising from the sale of Shares) in a brokerage or bank account outside his or her country. Holder understands that he or she may be required to report such accounts, assets or transactions to the tax or other authorities in his or her country. Holder also may be required to repatriate sale proceeds or other funds received as a result of Holder's participation in the Plan to his or her country through a designated bank or broker and/or within a certain time after receipt. In addition, Holder may be subject to tax payment and/or reporting obligations in connection with any income realized under the Plan and/or from the sale of Shares. Holder acknowledges that it is his or her responsibility to be compliant with all such requirements, and that Holder should consult his or her personal legal and tax advisors, as applicable, to ensure Holder's compliance.

25.Recovery of Erroneously Awarded Compensation. As an additional condition of receiving this Award, Holder agrees that the PSU and any proceeds or other benefits Holder may receive hereunder shall be subject to forfeiture and/or repayment to the Company to the extent and in the manner required (i) to comply with any requirements imposed under Applicable Law and/or the rules and regulations of the securities exchange or inter-dealer quotation system on which the Shares are listed or quoted, including, without limitation, pursuant to Section 954 of the Dodd-Frank Wall Street Reform and Consumer Protection Act of 2010 (collectively, the “Rules and Regulations”) and (ii) under the terms of

any policy adopted by the Company as of the date hereof or as may be amended from time to time to comply with Applicable Law or the Rules and Regulations(and such requirements shall be deemed incorporated into this Agreement without the consent of Holder). Further, if Holder receives any amount in excess of what Holder should have received under the terms of the PSU for any reason (including without limitation by reason of a financial restatement, mistake in calculations or administrative error), all as determined by the Administrator, then Holder shall be required to promptly repay any such excess amount to the Company. For purposes of the foregoing, Holder expressly and explicitly authorizes the Company to issue instructions, on Holder’s behalf, to any brokerage firm and/or third party administrator engaged by the Company to hold Holder’s Shares and other amounts acquired under the Plan to re-convey, transfer or otherwise return such Shares and/or other amounts to the Company. This Section 25 is not the Company’s exclusive remedy with respect to such matters.
