ILLUMINA, INC.

AMENDED AND RESTATED 2015 STOCK AND INCENTIVE PLAN

PERFORMANCE STOCK UNIT AGREEMENT FOR EMPLOYEES

This PERFORMANCE STOCK UNIT AGREEMENT (this “Agreement”) made as of this _____ day of ___________, 20___ , between Illumina, Inc., a Delaware corporation (the “Company”), and ___________________ (the “Participant”), is made pursuant to the terms of the Company’s Amended and Restated 2015 Stock and Incentive Plan (the “Plan”).

Section 1. Definitions. With the exception of the following, capitalized terms used in this Agreement but not defined herein shall have the meanings set forth in the Plan:

(a)“Audit Committee” means the Audit Committee of the Board of Directors.

(b) “Adjusted EPS”, for purposes of this Agreement, shall mean the consolidated non-GAAP earnings per share of Illumina, Inc. and its wholly-owned Subsidiaries (whether direct or indirect) for its fiscal year ending on [•], as calculated pursuant to the Company’s Non-GAAP Measures Policy and as adjusted by the Compensation Committee to prevent dilution or enlargement of the benefits or potential benefits intended to be made available with respect to the Award by eliminating the effects of any material undue and/or unintended gains or losses arising from items that are deemed to be not directly related to on-going core operations and which are either isolated events or are not reasonably expected to occur again with any regularity or predictability, including, but not limited to, the impact of mergers, acquisitions and/or divestitures, share buybacks, currency, interest rates and significant changes in tax or other laws and accounting rules. For the avoidance of doubt, Adjusted EPS will include the Award expense at 100% achievement rather than the prevailing accrual rate, and shall exclude the results of, and transactions with, less than wholly-owned Subsidiaries, whether direct or indirect. To the extent subsequent events occur that cause non-GAAP earnings per share to be revised during the period after a Current Report on Form 8-K is filed with the SEC through the Annual Report on Form 10-K filing date, Adjusted EPS shall be adjusted accordingly. These items are identified and quantified in the Company’s public financial reports.

(c)“Compensation Committee” means the Compensation Committee of the Board of Directors.

(d) “GAAP” means Generally Accepted Accounting Principles.

(e)“SEC” means Securities and Exchange Commission.

Section 2. Performance Stock Unit Award. The Company hereby confirms the grant to the Participant of an award (the “Award”) of Performance Stock Units (the “PSUs”). The PSUs are notional, non-voting units of measurement based on the Fair Market Value of the Common Stock, which will entitle the Participant to receive a payment, subject to the terms of the Plan and this Agreement (including, if applicable, the appendices attached hereto), in Common Stock.

The number of PSUs subject to this Award and the effective date of such grant are as follows:

Number of PSUs Granted: _______________

Date of Grant: [•]

Section 3. Vesting Requirements. The Award will vest in its entirety, if not previously forfeited, on [•] in the amount set forth below, subject to the Participant’s continued employment with the Company or any of its Subsidiaries through such date (the “Vesting Date”); provided, however, the Common Stock will not be released until the Compensation Committee certifies in writing that the performance targets have been achieved, as noted in Section 5. In accordance with Sections 2(ll) of the Plan, the Company’s Adjusted EPS has been established as a “Performance Criteria” upon which this performance-based Award will be made.

•If the Company’s Adjusted EPS for the fiscal year ending on [•], is equal to or less than the low Adjusted EPS performance target as approved by the Compensation Committee on the Grant Date, then no shares of Common Stock will be received by the Participant; or

•If the Company’s Adjusted EPS for the fiscal year ending on [•], is equal to or greater than the high Adjusted EPS performance target as approved by the Compensation Committee on the Date of Grant, then the number of shares of Common Stock that will be received by the Participant will be equal to 150% of the Award; or

•If the Company’s Adjusted EPS for the fiscal year ending on [•], is less than the high Adjusted EPS performance target and greater than the low Adjusted EPS performance target, in each case as approved by the Compensation Committee on the Date of Grant, then the number of shares of Common Stock that will be received by the Participant will be equal to a number between 50% and 150% of the Award as determined by linear interpolation for Adjusted EPS figures between the low and the high Adjusted EPS performance targets.

Section 4. Termination of Employment.

(a) General. [Except as otherwise provided in Section 4(b),] in the event of the termination of the Participant’s employment with the Company or any of its Subsidiaries for any reason, any unvested portion of any Award shall be immediately forfeited and automatically cancelled without further action of the Company. No Shares shall be issued or issuable with respect to any portion of the Award that terminates unvested and is forfeited.

(b) [Corporate Transactions. In the event that, during the 24-month period following a Corporate Transaction, the Participant’s employment is terminated by the Company (or other employer) for any reason other than death, disability or Cause, any PSUs that are unvested as of immediately prior to the date of the Corporate Transaction shall immediately vest in full at such time in an amount equal to 100% of the Number of PSUs Granted. For the purpose of this Section 4(b), “Cause” shall mean a termination of Participant’s employment in the event of (A) the Participant’s repeated failure or refusal to materially perform the Participant’s duties to the Company (other than by reason of temporary illness or other excused absence), as such duties existed immediately prior to the Corporate Transaction, (B) the Participant’s criminal conviction or a plea of nolo contendere with respect to a crime constituting a felony or crime of moral turpitude, or (C) the Participant’s engagement in an act of malfeasance, fraud, or dishonesty in connection with the Company that materially damages the business or reputation of the Company.]1

(c) For purposes of any applicable Change in Control Severance Agreement between the Participant and the Company (as the same may be amended or replaced), if in effect and applicable at the time of the termination of the Participant’s employment with the Company, “fully vested” with respect to any acceleration of vesting shall mean an amount equal to 100% of the Number of PSUs Granted, as set forth in Section 2.

Section 5. Payment of PSUs.

(a) General. Payment in respect of the PSUs hereunder shall be made in Common Stock as soon as practicable after such time the Compensation Committee determines that the applicable performance targets have been achieved and the Company’s Annual Report on Form 10-K is approved by the Audit Committee and filed with the SEC, but in any event by [•]. The number of Shares to be distributed in respect of the PSUs will be determined in accordance with the terms of this Agreement and the Plan, including, if applicable, the appendices attached hereto. [However, in the event the 2023 Share Reserve Increase is not approved by stockholders prior to a Vesting Date, the RSUs hereunder shall be settled in the form of a cash payment equal to the number of RSUs that vest on a Vesting Date, multiplied by the Fair Market Value of a Share on the Vesting Date.]2

(b) Withholding. The Participant hereby authorizes the Company to satisfy the obligations with regard to all income or withholding taxes (including federal, state and local tax) (the “Tax-Related Items”) by withholding otherwise deliverable Shares with respect to PSUs, provided, however, that (i) the Company shall only withhold the amount of Shares necessary to satisfy the withholding amount or such other amount determined by the Company, and (ii) no fraction of a Share shall be withheld to satisfy such Tax-Related Items. Subject to the provisions of this Section 5(b), the Participant will be deemed to have been issued the full number of Shares subject to the vested Award, notwithstanding that a number of the Shares are held back solely for the purpose of paying the Tax-Related Items due as a result of any aspect of the Award. If Shares are withheld pursuant to the foregoing provisions of this Section 5(b), then the amount of the Tax-Related Items equal to the value of a fraction of a Share shall be satisfied either by (i) the Participant through a payment to the Company by way of cash, check or other cash equivalent acceptable to the Company equal in value to such fraction of a Share, (ii) express authorization from the Participant to the Company to deduct such amount equal to such value from any amount then or thereafter payable by the Company to the Participant, or (iii) withholding from proceeds of the sale of Shares acquired upon settlement of the PSUs either through a voluntary sale or through a mandatory sale arranged by the Company (on the Participant’s behalf pursuant to the authorization without further consent). Notwithstanding the foregoing, the Compensation Committee may, in its sole discretion and without any further authorization by the Participant, elect to satisfy the obligations with regard to the Tax-Related Items by requiring that the Participant pay in whole or in part, by way of cash, check or other cash equivalent acceptable to the Company any amount of the Tax-Related Items. If the Participant shall fail to advance any payment under this Section 5(b) after a request by the Company, the Company is hereby expressly authorized by the Participant to deduct, in the Company’s discretion, any required payment for the Tax-Related Items from any amount then or thereafter payable by the Company to the Participant.
