 (REVERSE OF NOTE) 

ILLUMINA, INC. 
 5.800% Notes due
2025 
 Interest. 
 Illumina, Inc. (the
“Issuer”) promises to pay interest on the principal amount of this Note at the rate per annum described above. Cash interest on the Notes will accrue from the most recent date to which interest has been paid; or, if no interest has
been paid, from December 13, 2022. Interest on this Note will be paid to but not including the relevant Interest Payment Date. The Issuer will pay interest semiannually in arrears on each Interest Payment Date, commencing on June 12, 2023.
Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months in a manner consistent with Rule 11620(b) of the FINRA Uniform Practice Code.

 The Issuer shall pay interest on overdue principal from time to time on demand at the rate borne by the Notes and on overdue installments
of interest (without regard to any applicable grace periods) to the extent lawful. 
 Paying Agent. 

Initially, U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee (the
“Trustee”), will act as paying agent. The Issuer may change any paying agent without notice to the Holders. 
 Indenture; Defined Terms.

 This Note is one of the 5.800% Notes due 2025 (the “Notes”) issued under an indenture dated as of March 12, 2021
(the “Base Indenture”) by and between the Issuer and the Trustee, and established pursuant to an Officer’s Certificate dated December 13, 2022, issued pursuant to Section 2.01 and Section 2.03 thereof (together,
the “Indenture”). This Note is a “Security” and the Notes are “Securities” under the Indenture. 
 For
purposes of this Note, unless otherwise defined herein, capitalized terms herein are used as defined in the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “TIA”) as in effect on the date on which the Indenture was qualified under the TIA; provided, however, that in the event the Trust Indenture Act of 1939 is amended after
such date, “Trust Indenture Act” means, to the extent required by any such amendment, the Trust Indenture Act of 1939 as so amended. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of
Notes are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Note are inconsistent, the terms of the Indenture shall govern. 

  
 R-1 












 Denominations; Transfer; Exchange. 

The Notes are in registered form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 thereafter. A Holder
shall register the transfer or exchange of Notes in accordance with the Indenture. The Issuer may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or similar
governmental charges payable in connection therewith as permitted by the Indenture. Neither the Issuer nor the Registrar need issue, authenticate, register the transfer of or exchange any Notes or portions thereof for a period of fifteen
(15) days before the mailing of a notice of redemption, nor need the Issuer register the transfer or exchange of any Note selected for redemption in whole or in part. 

Amendment; Supplement; Waiver. 
 Subject to
certain exceptions set forth in the Indenture, the Notes and the provisions of the Indenture relating to the Notes may be amended or supplemented and any existing default or Event of Default or compliance with certain provisions may be waived with
the written consent of the Holders of at least a majority in aggregate principal amount of all series of Outstanding Securities (including the Notes) under the Indenture that are affected by such amendment, supplement or waiver (voting together as a
single class). Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Notes as provided in Section 7.01 of the Indenture. 

Redemption. 
 Prior to the Par Call Date (as
defined below), the Issuer may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price calculated by the Issuer equal to the greater of: 

(i)     (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be
redeemed discounted to the redemption date (assuming such Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day
months) at the Treasury Rate (as defined below), plus 25 basis points, less (b) interest accrued to the date of redemption, and 

(ii)    100% of the principal amount of the Notes to be redeemed, 

plus any accrued and unpaid interest on the Notes to be redeemed to, but not including, the redemption date. 

At any time on or after the Par Call Date, the Notes may be redeemed, in whole or in part at any time and from time to time, at the
Issuer’s option, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest on the Notes to be redeemed to, but not including, the redemption date. 

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a
redemption date will be payable on the Interest 

  
 R-2 












 
Payment Date to the registered Holders as of the close of business on the relevant record date according to the Notes and the Indenture. 

“Business Day” means any day other than a Saturday, a Sunday, or any other day on which banking institutions in The City of
New York or, with respect to any payment on the Notes, a place of payment, are authorized or required by law, regulation, or executive order to close. 

“Par Call Date” means November 12, 2025 (the date that is one month prior to the maturity of the Notes). 

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Issuer in accordance with the
following two paragraphs. 
 The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as
yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the redemption date based upon the yield or yields for the most recent day that appear after such
time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication)
(“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Issuer shall
select, as applicable: (i) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (ii) if there is no such Treasury
constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15
immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (iii) if there is no
such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant
maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date. 

If on the third Business Day preceding the redemption date, H.15 TCM is no longer published, the Issuer shall calculate the Treasury Rate
based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such redemption date of the United States Treasury security maturing on, or with a maturity
that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call
Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or
more United States Treasury securities maturing on the Par 

  
 R-3 












 
Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury securities
the United States Treasury security that is trading closest to par based upon the average of the bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with
the terms of this paragraph, the semi-annual yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City
time, of such United States Treasury security, and rounded to three decimal places. 
 The Issuer’s actions and determinations in
determining the redemption price shall be conclusive and binding for all purposes, absent manifest error. 
 Notice of any redemption will
be mailed or electronically delivered (or otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each Holder of the Notes to be redeemed with a copy to the
Trustee. 
 In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method
as the trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the
portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original note. For
so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary. 

Unless the Issuer defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes or
portions thereof called for redemption. 
 Any redemption or notice of redemption may, at the Issuer’s discretion, be subject to one or
more conditions precedent, and, at the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied. The Issuer shall provide written notice to the Trustee and the Holders prior to the
close of business two Business Days prior to the redemption date if any such redemption has been rescinded or delayed. 
 Change of Control Triggering
Event. 
 If a Change of Control Triggering Event (as defined below) occurs, unless the Issuer shall have exercised its right to redeem the
Notes as described above, the Issuer shall be required to make an offer (the “Change of Control Offer”) to each Holder of Notes to purchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of
that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of the Notes purchased, plus accrued and unpaid interest, if any, on the Notes purchased to but not including the date of purchase (the
“Change of Control Payment”); provided that after giving effect to 

  
 R-4 












 
the purchase, any Notes that remain outstanding shall have a minimum denomination of $2,000 and integral multiples of $1,000 above that amount. 

Within 30 days following any Change of Control Triggering Event or, at the Issuer’s option, prior to any Change of Control, but after
public announcement of the transaction that constitutes or may constitute the Change of Control, a notice will be mailed (or otherwise delivered in accordance with the applicable procedures of the Depositary) to Holders of the Notes with a copy to
the Trustee and the paying agent describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to purchase the Notes on the date specified in the notice, which date will be no earlier than 10 days
and no later than 60 days from the date such notice is mailed (or otherwise delivered in accordance with the applicable procedures of the Depositary) or, if the notice is mailed (or otherwise delivered) prior to the Change of Control, no earlier
than 10 days and no later than 60 days from the date on which the Change of Control Triggering Event occurs (the “Change of Control Payment Date”). The notice will, if mailed (or otherwise delivered) prior to the date of
consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. 

On the Change of Control Payment Date, the Issuer shall, to the extent lawful: 

 

	 	•	 	 accept or cause a third party to accept for payment all Notes or portions of Notes properly tendered pursuant to
the Change of Control Offer; 


  

	 	•	 	 deposit or cause a third party to deposit with the paying agent an amount equal to the Change of Control Payment
in respect of all Notes or portions of Notes properly tendered; and 


  

	 	•	 	 deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s
Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased. 


 The Issuer shall not
be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the
Issuer and the third party purchases all Notes properly tendered and not withdrawn under its offer in accordance with such requirements. In addition, the Issuer shall not purchase any Notes if there has occurred and is continuing on the Change of
Control Payment Date an Event of Default, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event. 

The Issuer shall comply in all material respects, to the extent applicable, with the requirements of Rule
14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the purchase of the Notes as a result of a
Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Issuer shall comply with those securities laws and regulations


  
 R-5 












 
and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict; rather, the Issuer shall be deemed to be in
compliance with those obligations if it complies with its obligation to purchase Notes upon a Change of Control Triggering Event in accordance with the Indenture, modified as necessary by the Issuer in good faith to permit compliance with any such
law or regulation. 
 Holders of Notes electing to have Notes purchased pursuant to a Change of Control Offer will be required to surrender
their Notes, with the form entitled “Purchase Exercise Notice Upon a Change of Control Triggering Event” on the reverse of the Note completed, to the paying agent at the address specified in the notice, or transfer their Notes to the
paying agent by book-entry transfer pursuant to the applicable procedures of the Depositary, prior to the close of business on the third Business Day prior to the Change of Control Payment Date. 

For purposes of these Change of Control Offer provisions of the Notes, the following terms are applicable: 

“Change of Control” means the occurrence of any of the following: 

(1)    the consummation of any transaction (including, without limitation, any merger or consolidation) the result of
which is that any “person” (as that term is used in Section 13(d) of the Exchange Act) (other than the Issuer or one of its Subsidiaries) becomes the beneficial owner (as defined in Rules 13d-3
and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the Issuer’s Voting Stock (as defined below) or other Voting Stock into which the Issuer’s Voting Stock is reclassified,
consolidated, exchanged, or changed, measured by voting power rather than number of shares; provided, however, that such person shall not be deemed the beneficial owner of, or to own beneficially, (A) any securities tendered
pursuant to a tender or exchange offer made by or on behalf of such person or any of such person’s affiliates until such tendered securities are accepted for purchase or exchange thereunder, or (B) any securities if such beneficial
ownership (i) arises solely as a result of a revocable proxy delivered in response to a proxy or consent solicitation made pursuant to the applicable rules and regulations under the Exchange Act, and (ii) is not also then reportable on
Schedule 13D (or any successor schedule) under the Exchange Act; 
 (2)    the direct or indirect sale, transfer,
conveyance, or other disposition (other than by way of merger or consolidation), in one or more series of related transactions, of all or substantially all of the Issuer’s assets and the assets of its Subsidiaries, taken as a whole, to one or
more “persons” (as that term is used in Section 13(d) of the Exchange Act) (other than to the Issuer or one of its Subsidiaries) (a “Transferee”), provided, however, that none of the circumstances in
this clause (2) will be a Change of Control if the persons that beneficially own the Issuer’s Voting Stock immediately prior to the transaction own, directly or indirectly, shares representing a majority of the total Voting Stock as
measured by voting power rather than number of shares of the Transferee in substantially the same proportions; 

(3)    the Issuer consolidates with, or merges with or into, any “person” (as that term is used in
Section 13(d) of the Exchange Act) or any such person consolidates with, or merges with or into, the Issuer, in either case, pursuant to a transaction in which any of the Issuer’s outstanding Voting Stock or the Voting Stock of such other
person is converted into or 

  
 R-6 












 
exchanged for cash, securities, or other property, other than pursuant to a transaction in which shares of the Issuer’s Voting Stock outstanding immediately prior to the transaction
constitute, or are converted into or exchanged for, a majority of the Voting Stock of the surviving person in substantially the same proportions immediately after giving effect to such transaction, in each case, measured by voting power rather than
number of shares; or 
 (4)    the adoption of a plan relating to the Issuer’s liquidation or dissolution by the
Board of Directors. 
 Notwithstanding clauses (1) through (3) above, a transaction will not be considered to be a Change of Control if
(a) the Issuer becomes a direct or indirect wholly-owned subsidiary of another entity and (b)(x) immediately following that transaction, the direct or indirect holders of the Voting Stock of such other entity are substantially the same as
the holders of the Issuer’s Voting Stock immediately prior to that transaction or (y) immediately following that transaction, no person is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such other
entity, in each case, measured by voting power rather than number of shares. 
 “Change of Control Triggering Event” means
the occurrence of both a Change of Control and a Rating Event. 
 “Investment Grade Rating” means a rating equal to or
higher than Baa3 (or the equivalent) by Moody’s (as defined below) and BBB- (or the equivalent) by S&P (as defined below) or the equivalent investment grade credit rating from any additional rating
agency or Rating Agencies (as defined below) selected by the Issuer. 
 “Moody’s” means Moody’s Investors
Service, Inc., or any successor thereto. 
 “Rating Agencies” means (1) each of Moody’s and S&P and
(2) if any of Moody’s and S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of its control, a “nationally recognized statistical rating organization” within the meaning
of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act selected by the Issuer as a replacement agency for Moody’s or S&P, or both of them, as the case may be, provided, that the Issuer shall give
notice of such appointment to the Trustee. 
 “Rating Event” means the rating on the Notes is lowered by each of the Rating
Agencies (or if there is only one Rating Agency, by such Rating Agency) and the Notes are rated below an Investment Grade Rating by each of the Rating Agencies (or if there is only one Rating Agency, by such Rating Agency), on any day during the
period commencing on the earlier of the date of the first public notice of the occurrence of a Change of Control or the Issuer’s intention to effect a Change of Control and ending 60 days following consummation of such Change of Control (which
period will be extended so long as the rating of the Notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies). 

“S&P” means S&P Global Ratings, a division of S&P Global Inc., or any successor thereto. 

  
 R-7 












 “Voting Stock” means, with respect to any specified “person” (as
that term is used in Section 13(d) of the Exchange Act) as of any date, the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person. 

Limitation on Liens. 
 Other than as provided in
this section or as provided in Section 3.08 of the Indenture, the Issuer will not, and will not permit any Subsidiary to, create or assume any Indebtedness secured by any Lien on any of its or their respective Principal Properties unless the
Notes are secured by such Lien equally and ratably with, or prior to, the Indebtedness secured by such Lien (together with, if the Issuer shall so determine, any of its other Indebtedness ranking equally with the Notes, it being understood that for
purposes hereof, Indebtedness which is secured by a Lien and Indebtedness which is not so secured shall not, solely by reason of such Lien, be deemed to be of different ranking) for so long as such other Indebtedness shall be so secured. This
restriction does not apply to Indebtedness that is secured by: 
  

	 	(1)	 Liens existing as of the initial issue date of the Notes; 



 

	 	(2)	 Liens securing only the Notes; 



 

	 	(3)	 Liens on property or shares of stock in respect of Indebtedness or any other obligations of a Person existing
at the time such Person becomes a Subsidiary of the Issuer or is merged into or consolidated with, or its assets are acquired by, the Issuer or any Subsidiary of the Issuer, or within 120 days thereafter (provided that such Lien was not incurred in
anticipation of such transaction and was in existence prior to such transaction) so long as such Lien extends only to such property thereon and the Indebtedness so secured is not increased; 



 

	 	(4)	 Liens to secure Indebtedness incurred for the purpose of all or any part of a property’s purchase price or
cost of construction or additions, repairs, alterations, or other improvements; provided that (a) the principal amount of any Indebtedness secured by such Lien does not exceed 100% of such property’s purchase price or cost, (b) such
Lien does not extend to or cover any other property other than the property so purchased, constructed, or on which such additions, repairs, alterations, or other improvements were so made and (c) such Lien is incurred prior to or within 270
days after the acquisition of such property or the completion of construction or such additions, repairs, alterations, or other improvements and the full operation of such property thereafter; 



 

	 	(5)	 Liens in favor of the U.S. or any state thereof or other political subdivision, or any agency or
instrumentality of any of the foregoing, to secure certain payments pursuant to any contract or statute; 


  

	 	(6)	 Liens for taxes or assessments or other governmental charges or levies which are not overdue for a period
exceeding 60 days unless such Liens are being contested in good faith and for which adequate reserves are being maintained, to the extent required by GAAP; 



  
 R-8 













	 	(7)	 title exceptions, easements, licenses, leases, and other similar Liens imposed by law or arising in the
ordinary course of business and that do not materially impair the use of the property subject thereto; 


  

	 	(8)	 Liens to secure obligations under worker’s compensation laws, unemployment compensation, old-age pensions, and other social security benefits or similar legislation; 


  

	 	(9)	 Liens arising out of legal proceedings, including Liens arising out of judgments or awards;

overdue for a period exceeding 60 days unless such Liens are being contested in good faith and for which adequate reserves are being maintained, to the extent required by GAAP; 



 

	 	(11)	 Liens incurred to secure the performance of statutory obligations, surety or appeal bonds, performance or return-of-money bonds, insurance, self-insurance, or other obligations of a like nature incurred in the ordinary course of business; 



 

	 	(12)	 Liens that are rights of set-off relating to the establishment of
depository relations with banks not given in connection with the issuance of Indebtedness; 


  

	 	(13)	 Liens arising out of conditional sale, title retention, consignment, or similar arrangements for the sale of
goods entered into by the Issuer or any of its Subsidiaries in the ordinary course of business; 


  

	 	(14)	 Liens in the Issuer’s favor or the favor of any of the Issuer’s Subsidiaries; or



  

	 	(15)	 Liens to secure any extension, renewal, refinancing, or refunding (or successive extensions, renewals,
refinancings, or refundings), in whole or in part, of any Indebtedness secured by Liens referred to in (1) through (14) above or Liens created in connection with any amendment, consent, or waiver relating to such Indebtedness, so long as such
Lien does not extend to any other property and the Indebtedness so secured does not exceed the fair market value (as determined by the Issuer’s board of directors) of the assets subject to such Liens at the time of such extension, renewal,
refinancing, or refunding, or such amendment, consent, or waiver, as the case may be. 


 Notwithstanding the foregoing,
any Liens securing the Notes granted pursuant to this section or as provided under Section 3.08 of the Indenture shall be automatically released and discharged upon the release by all holders of the Indebtedness secured by the Lien giving rise
to the Lien securing the Notes (including any deemed release upon payment in full of all obligations under such Indebtedness), or, with respect to any particular Principal Property, upon any sale, exchange or transfer of such Principal Property to
any Person that is not an affiliate of the Issuer. 

  
 R-9

and its Subsidiaries on a consolidated basis less (a) all current liabilities and (b) the value of all goodwill, trade names, trademarks, service marks, patents, unamortized debt discount and expense and other intangible assets, all as
shown on or reflected in the Issuer’s most recent consolidated balance sheet (including, without duplication, the notes related thereto) prepared in accordance with GAAP. 

“Finance Lease” means any Indebtedness represented by a lease obligation of a Person incurred with respect to real property
or equipment acquired or leased by such Person and used in its business that is required to be recorded as a finance lease in accordance with GAAP. 

“GAAP” means generally accepted accounting principles set forth in the opinions and pronouncements of the Public Company
Accounting Oversight Board (United States) and statements and pronouncements of the Financial Accounting Standards Board or in such other statements by such other entity as have been approved by a significant segment of the accounting profession,
which are in effect as of the date of determination. 
 “Indebtedness” of any Person means, without duplication
(1) any obligation of such Person for money borrowed, (2) any obligation of such Person evidenced by bonds, debentures, notes, or other similar instruments, (3) any reimbursement obligation of such Person in respect of letters of
credit or other similar instruments which support financial obligations which would otherwise become Indebtedness, and (4) any obligation of such Person under any Finance Lease; provided, however, that “Indebtedness” of such
Person shall not include any obligation of such Person to any Subsidiary of such Person or to any Person with respect to which such Person is a Subsidiary. 

“Lien” means any pledge, mortgage, lien, encumbrance, or other security interest. 

“Person” means any individual, corporation, limited liability company, partnership, joint venture, association, joint stock
company, trust, unincorporated organization, or government or any agency or political subdivision thereof or other similar entity. 

“Principal Property” means (1) any manufacturing or research and development facility, together with the land upon which
it is erected and fixtures comprising a part thereof, owned or leased by the Issuer or any Subsidiary and located within the continental U.S. and having a net book value which, on the date the determination as to whether a property is a Principal
Property is being made, exceeds 1.5% of the Issuer’s Consolidated Net Tangible Assets other than any such facility or a portion thereof which the Issuer’s board of directors determines in good faith, at any time on or prior to such date,
is not of material importance to the total business conducted, or assets owned, by the Issuer and its Subsidiaries as an entirety or (2) any shares of stock or Indebtedness of any Subsidiary owning a Principal Property. 

“property” means any property or asset, whether real, personal or mixed, or tangible or intangible, including shares of
capital stock. 

  
 R-10 












 “Subsidiary” of any specified Person means any corporation, limited
liability company, limited partnership, association or other business entity of which more than 50% of the total voting power of shares of capital stock entitled (without regard to the occurrence of any contingency) to vote in the election of
directors, managers or trustees thereof is at the time owned or controlled, directly or indirectly, by such Person or one or more of the other Subsidiaries of that Person or a combination thereof. 

Defaults and Remedies. 
 If an Event of Default
(other than certain bankruptcy Events of Default with respect to the Issuer) under the Indenture occurs with respect to the Notes and is continuing, then the Trustee may and, at the direction of the Holders of at least 25% in principal amount of the
outstanding Notes, shall by written notice, require the Issuer to repay immediately the entire principal amount of the Outstanding Notes, together with all accrued and unpaid interest and premium, if any. If a bankruptcy Event of Default with
respect to the Issuer occurs and is continuing, then the entire principal amount of the Outstanding Notes will automatically become due immediately and payable without any declaration or other act on the part of the Trustee or any Holder. Holders of
Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee is not obligated to enforce the Indenture or the Notes unless it has received indemnity or security as it requires. The Indenture permits, subject to
certain limitations therein provided, Holders of a majority in aggregate principal amount of the Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of certain
continuing defaults or Events of Default if it determines that withholding notice is in their interest. 
 For the avoidance of doubt, the
Issuer’s failure to purchase Notes tendered for purchase following the occurrence of a Change of Control Triggering Event in accordance with the provisions of Section 7 hereof shall constitute an Event of Default pursuant to
Section 4.01(b) of the Indenture. 
 Authentication. 

This Note shall not be valid until the Trustee manually signs the certificate of authentication on this Note. 

Abbreviations and Defined Terms. 
 Customary
abbreviations may be used in the name of a Holder of a Note or an assignee, such as: TEN COM (= tenants in common), TEN ENT (= tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (=
Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 
 CUSIP Numbers. 

Pursuant to a recommendation promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to

 (REVERSE OF NOTE) 

ILLUMINA, INC. 
 5.750% Notes due
2027 
 Interest. 
 Illumina, Inc. (the
“Issuer”) promises to pay interest on the principal amount of this Note at the rate per annum described above. Cash interest on the Notes will accrue from the most recent date to which interest has been paid; or, if no interest has
been paid, from December 13, 2022. Interest on this Note will be paid to but not including the relevant Interest Payment Date. The Issuer will pay interest semiannually in arrears on each Interest Payment Date, commencing on June 13, 2023.
Interest will be computed on the basis of a 360-day year consisting of twelve 30-day months in a manner consistent with Rule 11620(b) of the FINRA Uniform Practice Code.

 The Issuer shall pay interest on overdue principal from time to time on demand at the rate borne by the Notes and on overdue installments
of interest (without regard to any applicable grace periods) to the extent lawful. 
 Paying Agent. 

Initially, U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee (the
“Trustee”), will act as paying agent. The Issuer may change any paying agent without notice to the Holders. 
 Indenture; Defined Terms.

 This Note is one of the 5.750% Notes due 2027 (the “Notes”) issued under an indenture dated as of March 12, 2021
(the “Base Indenture”) by and between the Issuer and the Trustee, and established pursuant to an Officer’s Certificate dated December 13, 2022, issued pursuant to Section 2.01 and Section 2.03 thereof (together,
the “Indenture”). This Note is a “Security” and the Notes are “Securities” under the Indenture. 
 For
purposes of this Note, unless otherwise defined herein, capitalized terms herein are used as defined in the Indenture. The terms of the Notes include those stated in the Indenture and those made part of the Indenture by reference to the Trust
Indenture Act of 1939 (15 U.S.C. Sections 77aaa-77bbbb) (the “TIA”) as in effect on the date on which the Indenture was qualified under the TIA; provided, however, that in the event the Trust Indenture Act of 1939 is amended after
such date, “Trust Indenture Act” means, to the extent required by any such amendment, the Trust Indenture Act of 1939 as so amended. Notwithstanding anything to the contrary herein, the Notes are subject to all such terms, and Holders of
Notes are referred to the Indenture and the TIA for a statement of them. To the extent the terms of the Indenture and this Note are inconsistent, the terms of the Indenture shall govern. 

Denominations; Transfer; Exchange. 
 The Notes
are in registered form, without coupons, in minimum denominations of $2,000 and integral multiples of $1,000 thereafter. A Holder shall register the transfer or exchange of 

  
 R-1 












 
Notes in accordance with the Indenture. The Issuer may require a Holder, among other things, to furnish appropriate endorsements and transfer documents and to pay certain transfer taxes or
similar governmental charges payable in connection therewith as permitted by the Indenture. Neither the Issuer nor the Registrar need issue, authenticate, register the transfer of or exchange any Notes or portions thereof for a period of fifteen
(15) days before the mailing of a notice of redemption, nor need the Issuer register the transfer or exchange of any Note selected for redemption in whole or in part. 

Amendment; Supplement; Waiver. 
 Subject to
certain exceptions set forth in the Indenture, the Notes and the provisions of the Indenture relating to the Notes may be amended or supplemented and any existing default or Event of Default or compliance with certain provisions may be waived with
the written consent of the Holders of at least a majority in aggregate principal amount of all series of Outstanding Securities (including the Notes) under the Indenture that are affected by such amendment, supplement or waiver (voting together as a
single class). Without notice to or consent of any Holder, the parties thereto may amend or supplement the Indenture and the Notes as provided in Section 7.01 of the Indenture. 

Redemption. 
 Prior to the Par Call Date (as
defined below), the Issuer may redeem the Notes at its option, in whole or in part, at any time and from time to time, at a redemption price calculated by the Issuer equal to the greater of: 

(i)     (a) the sum of the present values of the remaining scheduled payments of principal and interest on the Notes to be
redeemed discounted to the redemption date (assuming such Notes matured on the Par Call Date) on a semi-annual basis (assuming a 360-day year consisting of twelve 30-day
months) at the Treasury Rate (as defined below), plus 30 basis points, less (b) interest accrued to the date of redemption, and 

(ii)    100% of the principal amount of the Notes to be redeemed, 

plus any accrued and unpaid interest on the Notes to be redeemed to, but not including, the redemption date. 

At any time on or after the Par Call Date, the Notes may be redeemed, in whole or in part at any time and from time to time, at the
Issuer’s option, at a redemption price equal to 100% of the principal amount thereof, plus accrued and unpaid interest on the Notes to be redeemed to, but not including, the redemption date. 

Notwithstanding the foregoing, installments of interest on Notes that are due and payable on Interest Payment Dates falling on or prior to a
redemption date will be payable on the Interest Payment Date to the registered Holders as of the close of business on the relevant record date according to the Notes and the Indenture.

 “Business Day” means any day other than a Saturday, a Sunday, or any other
day on which banking institutions in The City of New York or, with respect to any payment on the Notes, a place of payment, are authorized or required by law, regulation, or executive order to close. 

“Par Call Date” means November 13, 2027 (the date that is one month prior to the maturity of the Notes). 

“Treasury Rate” means, with respect to any redemption date, the yield determined by the Issuer in accordance with the
following two paragraphs. 
 The Treasury Rate shall be determined by the Issuer after 4:15 p.m., New York City time (or after such time as
yields on U.S. government securities are posted daily by the Board of Governors of the Federal Reserve System), on the third Business Day preceding the redemption date based upon the yield or yields for the most recent day that appear after such
time on such day in the most recent statistical release published by the Board of Governors of the Federal Reserve System designated as “Selected Interest Rates (Daily) - H.15” (or any successor designation or publication)
(“H.15”) under the caption “U.S. government securities–Treasury constant maturities–Nominal” (or any successor caption or heading) (“H.15 TCM”). In determining the Treasury Rate, the Issuer shall
select, as applicable: (i) the yield for the Treasury constant maturity on H.15 exactly equal to the period from the redemption date to the Par Call Date (the “Remaining Life”); or (ii) if there is no such Treasury
constant maturity on H.15 exactly equal to the Remaining Life, the two yields – one yield corresponding to the Treasury constant maturity on H.15 immediately shorter than and one yield corresponding to the Treasury constant maturity on H.15
immediately longer than the Remaining Life – and shall interpolate to the Par Call Date on a straight-line basis (using the actual number of days) using such yields and rounding the result to three decimal places; or (iii) if there is no
such Treasury constant maturity on H.15 shorter than or longer than the Remaining Life, the yield for the single Treasury constant maturity on H.15 closest to the Remaining Life. For purposes of this paragraph, the applicable Treasury constant
maturity or maturities on H.15 shall be deemed to have a maturity date equal to the relevant number of months or years, as applicable, of such Treasury constant maturity from the redemption date. 

If on the third Business Day preceding the redemption date, H.15 TCM is no longer published, the Issuer shall calculate the Treasury Rate
based on the rate per annum equal to the semi-annual equivalent yield to maturity at 11:00 a.m., New York City time, on the second Business Day preceding such redemption date of the United States Treasury security maturing on, or with a maturity
that is closest to, the Par Call Date, as applicable. If there is no United States Treasury security maturing on the Par Call Date but there are two or more United States Treasury securities with a maturity date equally distant from the Par Call
Date, one with a maturity date preceding the Par Call Date and one with a maturity date following the Par Call Date, the Issuer shall select the United States Treasury security with a maturity date preceding the Par Call Date. If there are two or
more United States Treasury securities maturing on the Par Call Date or two or more United States Treasury securities meeting the criteria of the preceding sentence, the Issuer shall select from among these two or more United States Treasury
securities the United States Treasury security that is trading closest to par based upon the average of the 

  
 R-3 












 
bid and asked prices for such United States Treasury securities at 11:00 a.m., New York City time. In determining the Treasury Rate in accordance with the terms of this paragraph, the semi-annual
yield to maturity of the applicable United States Treasury security shall be based upon the average of the bid and asked prices (expressed as a percentage of principal amount) at 11:00 a.m., New York City time, of such United States Treasury
security, and rounded to three decimal places. 
 The Issuer’s actions and determinations in determining the redemption price shall be
conclusive and binding for all purposes, absent manifest error. 
 Notice of any redemption will be mailed or electronically delivered (or
otherwise transmitted in accordance with the depositary’s procedures) at least 10 days but not more than 60 days before the redemption date to each Holder of the Notes to be redeemed with a copy to the Trustee. 

In the case of a partial redemption, selection of the Notes for redemption will be made pro rata, by lot or by such other method as the
trustee in its sole discretion deems appropriate and fair. No Notes of a principal amount of $2,000 or less will be redeemed in part. If any Note is to be redeemed in part only, the notice of redemption that relates to the Note will state the
portion of the principal amount of the Note to be redeemed. A new Note in a principal amount equal to the unredeemed portion of the Note will be issued in the name of the Holder of the Note upon surrender for cancellation of the original note. For
so long as the Notes are held by DTC (or another depositary), the redemption of the Notes shall be done in accordance with the policies and procedures of the depositary. 

Unless the Issuer defaults in payment of the redemption price, on and after the redemption date interest will cease to accrue on the Notes or
portions thereof called for redemption. 
 Any redemption or notice of redemption may, at the Issuer’s discretion, be subject to one or
more conditions precedent, and, at the Issuer’s discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied. The Issuer shall provide written notice to the Trustee and the Holders prior to the
close of business two Business Days prior to the redemption date if any such redemption has been rescinded or delayed. 
 Change of Control Triggering
Event. 
 If a Change of Control Triggering Event (as defined below) occurs, unless the Issuer shall have exercised its right to redeem the
Notes as described above, the Issuer shall be required to make an offer (the “Change of Control Offer”) to each Holder of Notes to purchase all or any part (equal to $2,000 or an integral multiple of $1,000 in excess thereof) of
that Holder’s Notes at a purchase price in cash equal to 101% of the aggregate principal amount of the Notes purchased, plus accrued and unpaid interest, if any, on the Notes purchased to but not including the date of purchase (the
“Change of Control Payment”); provided that after giving effect to the purchase, any Notes that remain outstanding shall have a minimum denomination of $2,000 and integral multiples of $1,000 above that amount. 

  
 R-4 












 Within 30 days following any Change of Control Triggering Event or, at the Issuer’s
option, prior to any Change of Control, but after public announcement of the transaction that constitutes or may constitute the Change of Control, a notice will be mailed (or otherwise delivered in accordance with the applicable procedures of the
Depositary) to Holders of the Notes with a copy to the Trustee and the paying agent describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to purchase the Notes on the date specified in the
notice, which date will be no earlier than 10 days and no later than 60 days from the date such notice is mailed (or otherwise delivered in accordance with the applicable procedures of the Depositary) or, if the notice is mailed (or otherwise
delivered) prior to the Change of Control, no earlier than 10 days and no later than 60 days from the date on which the Change of Control Triggering Event occurs (the “Change of Control Payment Date”). The notice will, if mailed (or
otherwise delivered) prior to the date of consummation of the Change of Control, state that the offer to purchase is conditioned on the Change of Control Triggering Event occurring on or prior to the Change of Control Payment Date. 

On the Change of Control Payment Date, the Issuer shall, to the extent lawful: 

 

	 	•	 	 accept or cause a third party to accept for payment all Notes or portions of Notes properly tendered pursuant to
the Change of Control Offer; 


  

	 	•	 	 deposit or cause a third party to deposit with the paying agent an amount equal to the Change of Control Payment
in respect of all Notes or portions of Notes properly tendered; and 


  

	 	•	 	 deliver or cause to be delivered to the Trustee the Notes properly accepted together with an Officer’s
Certificate stating the aggregate principal amount of Notes or portions of Notes being purchased. 


 The Issuer shall not
be required to make a Change of Control Offer upon the occurrence of a Change of Control Triggering Event if a third party makes such an offer in the manner, at the times and otherwise in compliance with the requirements for an offer made by the
Issuer and the third party purchases all Notes properly tendered and not withdrawn under its offer in accordance with such requirements. In addition, the Issuer shall not purchase any Notes if there has occurred and is continuing on the Change of
Control Payment Date an Event of Default, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event. 

The Issuer shall comply in all material respects, to the extent applicable, with the requirements of Rule
14e-1 under the Exchange Act, and any other securities laws and regulations thereunder to the extent those laws and regulations are applicable in connection with the purchase of the Notes as a result of a
Change of Control Triggering Event. To the extent that the provisions of any such securities laws or regulations conflict with the Change of Control Offer provisions of the Notes, the Issuer shall comply with those securities laws and regulations
and shall not be deemed to have breached its obligations under the Change of Control Offer provisions of the Notes by virtue of any such conflict; rather, the Issuer shall be deemed to be in compliance with those obligations if it complies with its
obligation to purchase Notes upon a 

  
 R-5 












 
Change of Control Triggering Event in accordance with the Indenture, modified as necessary by the Issuer in good faith to permit compliance with any such law or regulation. 

Holders of Notes electing to have Notes purchased pursuant to a Change of Control Offer will be required to surrender their Notes, with the
form entitled “Purchase Exercise Notice Upon a Change of Control Triggering Event” on the reverse of the Note completed, to the paying agent at the address specified in the notice, or transfer their Notes to the paying agent by book-entry
transfer pursuant to the applicable procedures of the Depositary, prior to the close of business on the third Business Day prior to the Change of Control Payment Date. 

For purposes of these Change of Control Offer provisions of the Notes, the following terms are applicable: 

“Change of Control” means the occurrence of any of the following: 

(1)    the consummation of any transaction (including, without limitation, any merger or consolidation) the result of
which is that any “person” (as that term is used in Section 13(d) of the Exchange Act) (other than the Issuer or one of its Subsidiaries) becomes the beneficial owner (as defined in Rules 13d-3
and 13d-5 under the Exchange Act), directly or indirectly, of more than 50% of the Issuer’s Voting Stock (as defined below) or other Voting Stock into which the Issuer’s Voting Stock is reclassified,
consolidated, exchanged, or changed, measured by voting power rather than number of shares; provided, however, that such person shall not be deemed the beneficial owner of, or to own beneficially, (A) any securities tendered
pursuant to a tender or exchange offer made by or on behalf of such person or any of such person’s affiliates until such tendered securities are accepted for purchase or exchange thereunder, or (B) any securities if such beneficial
ownership (i) arises solely as a result of a revocable proxy delivered in response to a proxy or consent solicitation made pursuant to the applicable rules and regulations under the Exchange Act, and (ii) is not also then reportable on
Schedule 13D (or any successor schedule) under the Exchange Act; 
 (2)    the direct or indirect sale, transfer,
conveyance, or other disposition (other than by way of merger or consolidation), in one or more series of related transactions, of all or substantially all of the Issuer’s assets and the assets of its Subsidiaries, taken as a whole, to one or
more “persons” (as that term is used in Section 13(d) of the Exchange Act) (other than to the Issuer or one of its Subsidiaries) (a “Transferee”), provided, however, that none of the circumstances in
this clause (2) will be a Change of Control if the persons that beneficially own the Issuer’s Voting Stock immediately prior to the transaction own, directly or indirectly, shares representing a majority of the total Voting Stock as
measured by voting power rather than number of shares of the Transferee in substantially the same proportions; 

(3)    the Issuer consolidates with, or merges with or into, any “person” (as that term is used in
Section 13(d) of the Exchange Act) or any such person consolidates with, or merges with or into, the Issuer, in either case, pursuant to a transaction in which any of the Issuer’s outstanding Voting Stock or the Voting Stock of such other
person is converted into or exchanged for cash, securities, or other property, other than pursuant to a transaction in which shares of the Issuer’s Voting Stock outstanding immediately prior to the transaction constitute, or are converted into
or exchanged for, a majority of the Voting Stock of the surviving person in 

  
 R-6 












 
substantially the same proportions immediately after giving effect to such transaction, in each case, measured by voting power rather than number of shares; or 

(4)    the adoption of a plan relating to the Issuer’s liquidation or dissolution by the Board of Directors. 

Notwithstanding clauses (1) through (3) above, a transaction will not be considered to be a Change of Control if (a) the Issuer
becomes a direct or indirect wholly-owned subsidiary of another entity and (b)(x) immediately following that transaction, the direct or indirect holders of the Voting Stock of such other entity are substantially the same as the holders of the
Issuer’s Voting Stock immediately prior to that transaction or (y) immediately following that transaction, no person is the beneficial owner, directly or indirectly, of more than 50% of the Voting Stock of such other entity, in each case,
measured by voting power rather than number of shares. 
 “Change of Control Triggering Event” means the occurrence of both
a Change of Control and a Rating Event. 
 “Investment Grade Rating” means a rating equal to or higher than Baa3 (or the
equivalent) by Moody’s (as defined below) and BBB- (or the equivalent) by S&P (as defined below) or the equivalent investment grade credit rating from any additional rating agency or Rating Agencies
(as defined below) selected by the Issuer. 
 “Moody’s” means Moody’s Investors Service, Inc., or any successor
thereto. 
 “Rating Agencies” means (1) each of Moody’s and S&P and (2) if any of Moody’s and
S&P ceases to rate the Notes or fails to make a rating of the Notes publicly available for reasons outside of its control, a “nationally recognized statistical rating organization” within the meaning of Rule 15c3-1(c)(2)(vi)(F) under the Exchange Act selected by the Issuer as a replacement agency for Moody’s or S&P, or both of them, as the case may be, provided, that the Issuer shall give notice of such
appointment to the Trustee. 
 “Rating Event” means the rating on the Notes is lowered by each of the Rating Agencies (or
if there is only one Rating Agency, by such Rating Agency) and the Notes are rated below an Investment Grade Rating by each of the Rating Agencies (or if there is only one Rating Agency, by such Rating Agency), on any day during the period
commencing on the earlier of the date of the first public notice of the occurrence of a Change of Control or the Issuer’s intention to effect a Change of Control and ending 60 days following consummation of such Change of Control (which period
will be extended so long as the rating of the Notes is under publicly announced consideration for a possible downgrade by any of the Rating Agencies). 

“S&P” means S&P Global Ratings, a division of S&P Global Inc., or any successor thereto. 

“Voting Stock” means, with respect to any specified “person” (as that term is used in Section 13(d) of the
Exchange Act) as of any date, the capital stock of such person that is at the time entitled to vote generally in the election of the board of directors of such person. 

  
 R-7 












 Limitation on Liens. 

Other than as provided in this section or as provided in Section 3.08 of the Indenture, the Issuer will not, and will not permit any
Subsidiary to, create or assume any Indebtedness secured by any Lien on any of its or their respective Principal Properties unless the Notes are secured by such Lien equally and ratably with, or prior to, the Indebtedness secured by such Lien
(together with, if the Issuer shall so determine, any of its other Indebtedness ranking equally with the Notes, it being understood that for purposes hereof, Indebtedness which is secured by a Lien and Indebtedness which is not so secured shall not,
solely by reason of such Lien, be deemed to be of different ranking) for so long as such other Indebtedness shall be so secured. This restriction does not apply to Indebtedness that is secured by: 

 

	 	(1)	 Liens existing as of the initial issue date of the Notes; 



 

	 	(2)	 Liens securing only the Notes; 



 

	 	(3)	 Liens on property or shares of stock in respect of Indebtedness or any other obligations of a Person existing
at the time such Person becomes a Subsidiary of the Issuer or is merged into or consolidated with, or its assets are acquired by, the Issuer or any Subsidiary of the Issuer, or within 120 days thereafter (provided that such Lien was not incurred in
anticipation of such transaction and was in existence prior to such transaction) so long as such Lien extends only to such property thereon and the Indebtedness so secured is not increased; 



 

	 	(4)	 Liens to secure Indebtedness incurred for the purpose of all or any part of a property’s purchase price or
cost of construction or additions, repairs, alterations, or other improvements; provided that (a) the principal amount of any Indebtedness secured by such Lien does not exceed 100% of such property’s purchase price or cost, (b) such
Lien does not extend to or cover any other property other than the property so purchased, constructed, or on which such additions, repairs, alterations, or other improvements were so made and (c) such Lien is incurred prior to or within 270
days after the acquisition of such property or the completion of construction or such additions, repairs, alterations, or other improvements and the full operation of such property thereafter; 



 

	 	(5)	 Liens in favor of the U.S. or any state thereof or other political subdivision, or any agency or
instrumentality of any of the foregoing, to secure certain payments pursuant to any contract or statute; 


  

	 	(6)	 Liens for taxes or assessments or other governmental charges or levies which are not overdue for a period
exceeding 60 days unless such Liens are being contested in good faith and for which adequate reserves are being maintained, to the extent required by GAAP; 


  

	 	(7)	 title exceptions, easements, licenses, leases, and other similar Liens imposed by law or arising in the
ordinary course of business and that do not materially impair the use of the property subject thereto; 



  
 R-8 













	 	(8)	 Liens to secure obligations under worker’s compensation laws, unemployment compensation, old-age pensions, and other social security benefits or similar legislation; 


  

	 	(9)	 Liens arising out of legal proceedings, including Liens arising out of judgments or awards;

overdue for a period exceeding 60 days unless such Liens are being contested in good faith and for which adequate reserves are being maintained, to the extent required by GAAP; 



 

	 	(11)	 Liens incurred to secure the performance of statutory obligations, surety or appeal bonds, performance or return-of-money bonds, insurance, self-insurance, or other obligations of a like nature incurred in the ordinary course of business; 



 

	 	(12)	 Liens that are rights of set-off relating to the establishment of
depository relations with banks not given in connection with the issuance of Indebtedness; 


  

	 	(13)	 Liens arising out of conditional sale, title retention, consignment, or similar arrangements for the sale of
goods entered into by the Issuer or any of its Subsidiaries in the ordinary course of business; 


  

	 	(14)	 Liens in the Issuer’s favor or the favor of any of the Issuer’s Subsidiaries; or



  

	 	(15)	 Liens to secure any extension, renewal, refinancing, or refunding (or successive extensions, renewals,
refinancings, or refundings), in whole or in part, of any Indebtedness secured by Liens referred to in (1) through (14) above or Liens created in connection with any amendment, consent, or waiver relating to such Indebtedness, so long as such
Lien does not extend to any other property and the Indebtedness so secured does not exceed the fair market value (as determined by the Issuer’s board of directors) of the assets subject to such Liens at the time of such extension, renewal,
refinancing, or refunding, or such amendment, consent, or waiver, as the case may be. 


 Notwithstanding the foregoing,
any Liens securing the Notes granted pursuant to this section or as provided under Section 3.08 of the Indenture shall be automatically released and discharged upon the release by all holders of the Indebtedness secured by the Lien giving rise
to the Lien securing the Notes (including any deemed release upon payment in full of all obligations under such Indebtedness), or, with respect to any particular Principal Property, upon any sale, exchange or transfer of such Principal Property to
any Person that is not an affiliate of the Issuer. 
 For purposes of these Limitation on Liens provisions of the Notes, the following terms
are applicable: 

  
 R-9 












 “Consolidated Net Tangible Assets” means, as of any date of determination,
the total assets of the Issuer and its Subsidiaries on a consolidated basis less (a) all current liabilities and (b) the value of all goodwill, trade names, trademarks, service marks, patents, unamortized debt discount and expense and
other intangible assets, all as shown on or reflected in the Issuer’s most recent consolidated balance sheet (including, without duplication, the notes related thereto) prepared in accordance with GAAP. 

“Finance Lease” means any Indebtedness represented by a lease obligation of a Person incurred with respect to real property
or equipment acquired or leased by such Person and used in its business that is required to be recorded as a finance lease in accordance with GAAP. 

“GAAP” means generally accepted accounting principles set forth in the opinions and pronouncements of the Public Company
Accounting Oversight Board (United States) and statements and pronouncements of the Financial Accounting Standards Board or in such other statements by such other entity as have been approved by a significant segment of the accounting profession,
which are in effect as of the date of determination. 
 “Indebtedness” of any Person means, without duplication
(1) any obligation of such Person for money borrowed, (2) any obligation of such Person evidenced by bonds, debentures, notes, or other similar instruments, (3) any reimbursement obligation of such Person in respect of letters of
credit or other similar instruments which support financial obligations which would otherwise become Indebtedness, and (4) any obligation of such Person under any Finance Lease; provided, however, that “Indebtedness” of such
Person shall not include any obligation of such Person to any Subsidiary of such Person or to any Person with respect to which such Person is a Subsidiary. 

“Lien” means any pledge, mortgage, lien, encumbrance, or other security interest. 

“Person” means any individual, corporation, limited liability company, partnership, joint venture, association, joint stock
company, trust, unincorporated organization, or government or any agency or political subdivision thereof or other similar entity. 

“Principal Property” means (1) any manufacturing or research and development facility, together with the land upon which
it is erected and fixtures comprising a part thereof, owned or leased by the Issuer or any Subsidiary and located within the continental U.S. and having a net book value which, on the date the determination as to whether a property is a Principal
Property is being made, exceeds 1.5% of the Issuer’s Consolidated Net Tangible Assets other than any such facility or a portion thereof which the Issuer’s board of directors determines in good faith, at any time on or prior to such date,
is not of material importance to the total business conducted, or assets owned, by the Issuer and its Subsidiaries as an entirety or (2) any shares of stock or Indebtedness of any Subsidiary owning a Principal Property. 

“property” means any property or asset, whether real, personal or mixed, or tangible or intangible, including shares of
capital stock. 
 “Subsidiary” of any specified Person means any corporation, limited liability company, limited
partnership, association or other business entity of which more than 50% of the total 

  
 R-10 












 
voting power of shares of capital stock entitled (without regard to the occurrence of any contingency) to vote in the election of directors, managers or trustees thereof is at the time owned or
controlled, directly or indirectly, by such Person or one or more of the other Subsidiaries of that Person or a combination thereof. 
 Defaults and
Remedies. 
 If an Event of Default (other than certain bankruptcy Events of Default with respect to the Issuer) under the Indenture occurs
with respect to the Notes and is continuing, then the Trustee may and, at the direction of the Holders of at least 25% in principal amount of the outstanding Notes, shall by written notice, require the Issuer to repay immediately the entire
principal amount of the Outstanding Notes, together with all accrued and unpaid interest and premium, if any. If a bankruptcy Event of Default with respect to the Issuer occurs and is continuing, then the entire principal amount of the Outstanding
Notes will automatically become due immediately and payable without any declaration or other act on the part of the Trustee or any Holder. Holders of Notes may not enforce the Indenture or the Notes except as provided in the Indenture. The Trustee
is not obligated to enforce the Indenture or the Notes unless it has received indemnity or security as it requires. The Indenture permits, subject to certain limitations therein provided, Holders of a majority in aggregate principal amount of the
Notes then outstanding to direct the Trustee in its exercise of any trust or power. The Trustee may withhold from Holders of Notes notice of certain continuing defaults or Events of Default if it determines that withholding notice is in their
interest. 
 For the avoidance of doubt, the Issuer’s failure to purchase Notes tendered for purchase following the occurrence of a
Change of Control Triggering Event in accordance with the provisions of Section 7 hereof shall constitute an Event of Default pursuant to Section 4.01(b) of the Indenture. 

Authentication. 
 This Note shall not be valid
until the Trustee manually signs the certificate of authentication on this Note. 
 Abbreviations and Defined Terms. 

Customary abbreviations may be used in the name of a Holder of a Note or an assignee, such as: TEN COM (= tenants in common), TEN ENT (=
tenants by the entireties), JT TEN (= joint tenants with right of survivorship and not as tenants in common), CUST (= Custodian), and U/G/M/A (= Uniform Gifts to Minors Act). 

CUSIP Numbers. 
 Pursuant to a recommendation
promulgated by the Committee on Uniform Security Identification Procedures, the Issuer has caused CUSIP numbers to be printed on the Notes as a convenience to the Holders of the Notes. No representation is made as to the accuracy of such numbers as
printed on the Notes and reliance may be placed only on the other identification numbers printed hereon. 

  
 R-11

The laws of the State of New York shall govern the Indenture and this Note thereof. 

Miscellaneous. 
 The Issuer shall not be required
to pay any additional amounts on any of the Notes to any Person in respect of any tax, assessment or governmental charge withheld or deducted. The Issuer or the Trustee may require payment of a sum sufficient to cover any tax or governmental charge
that may be imposed in connection with any exchange or registration of Notes. No service charge shall be made for any such transaction. 
 The Notes shall
not be entitled to the benefit of any sinking fund.
