PRELIMINARY PROSPECTUS

Biogen Inc.

Offer to Exchange

up to $700,731,000 of our outstanding unregistered 3.250% Senior Notes due 2051

for a like principal amount of 3.250% Senior Notes due 2051

that have been registered under the Securities Act of 1933, as amended

Biogen Inc. is offering $700,731,000 aggregate principal amount of new 3.250% Senior Notes due 2051 (the “New Notes”) in exchange for an equal amount of outstanding 3.250% Senior Notes due 2051 (the “Old Notes”).

Each broker-dealer that receives New Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of the New Notes. The letter of transmittal accompanying this prospectus states that, by so acknowledging and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with resales of New Notes received in exchange for Old Notes where such Old Notes were acquired by such broker-dealer as a result of market-making activities or other trading activities. We have agreed that, for a period ending on the earlier of (i) 90 days from the date on which this registration statement is declared effective and (ii) the date on which no participating broker-dealer is required to deliver a prospectus in connection with market-making or other trading activities, we will make this prospectus available to any broker-dealer for use in connection with any such resale. See “Plan of Distribution.”

Investing in the New Notes to be issued in the exchange offer involves certain risks. See “Risk Factors” beginning on page 9.

Neither the U.S. Securities and Exchange Commission nor any state securities commission has approved or disapproved of these securities or passed upon the adequacy or accuracy of this prospectus. Any representation to the contrary is a criminal offense.

RISK FACTORS

Participating in the exchange offer involves risks. You should carefully consider the following risk factors as well as the other information contained or incorporated by reference in this prospectus, including the discussion of risk factors in our Quarterly Report on Form 10-Q for the quarter ended March 31, 2022, which is incorporated by reference into this prospectus, before making a decision to participate in the exchange offer. Some of these factors relate principally to our business and the industry in which we operate. Other factors relate principally to your participation in the exchange offer. If any of the matters described in such risk factors were to occur, our business, financial condition, results of operations, cash flows or prospects could be materially adversely affected. The risks and uncertainties described below are not the only ones we face. Additional risks and uncertainties not presently known to us or that we currently deem immaterial may also materially adversely affect our business, financial condition, results of operations, cash flows or prospects. If any of these risks were to materialize, our ability to pay interest on the New Notes when due or to repay the New Notes at maturity could be adversely affected, and the trading prices of the New Notes could decline substantially.

Risks Related to the New Notes

Our indebtedness could adversely affect our business and limit our ability to plan for or respond to changes in our business.

We currently have indebtedness and significant contingent liabilities, including milestone and royalty payment obligations. We may also incur additional debt in the future. For example, we have the ability to draw down our $1.0 billion revolving credit facility in the ordinary course, which would have the effect of increasing our indebtedness. This indebtedness could have important consequences to our business; for example, such obligations could:

The New Notes are effectively junior to the existing and future liabilities of our subsidiaries, which include substantially all of our operating liabilities, and to any secured debt we may incur to the extent of the assets securing that debt.

Our subsidiaries, which generate the substantial majority of our revenues and carry substantially all of our operating liabilities, are separate and distinct legal entities. Biogen Inc., the issuer of the New Notes, is primarily a holding company with limited operations of its own. Accordingly, we depend on our subsidiaries’ earnings and advances or loans made by our subsidiaries to us to provide funds necessary to meet our obligations, including the payments of principal and interest on the New Notes. If we are unable to access the cash flows of our subsidiaries, we would be unable to meet our debt obligations. Our subsidiaries have no obligation to pay any amounts due on the New Notes. In addition, any payment of dividends, loans or advances to us by our subsidiaries could be subject to statutory or contractual restrictions. Payments to us by our subsidiaries will also be contingent upon the subsidiaries’ earnings and business considerations. Our right to receive any assets of any of our subsidiaries upon its bankruptcy, liquidation or reorganization, and therefore the right of the holders of the New Notes to participate in those assets, will be effectively subordinated to the claims of that subsidiary’s creditors, including trade creditors. In addition, even if we are a creditor of any of our subsidiaries, our right as a

9

creditor would be subordinate to any security interest in the assets of our subsidiaries and any indebtedness of our subsidiaries senior to that held by us. As of March 31, 2022, neither we nor our subsidiaries had any secured debt outstanding, and our subsidiaries had total liabilities of approximately $5.3 billion.

The New Notes are our senior unsecured obligations and will rank equal in right of payment with our other existing and future senior unsecured obligations that are not, by their terms, expressly subordinated in right of payment to the New Notes, including $1.0 billion aggregate principal amount of our 3.625% Senior Notes due September 15, 2022, $1.75 billion aggregate principal amount of our 4.050% Senior Notes due September 15, 2025, $1.5 billion aggregate principal amount of our 2.250% Senior Notes due May 1, 2030, $1.125 billion aggregate principal amount of our 5.200% Senior Notes due September 15, 2045, and $1.5 billion aggregate principal amount of our 3.150% Senior Notes due May 1, 2050, as well as any outstanding Old Notes that may remain outstanding after the consummation of the exchange offer. The New Notes are not secured by any of our assets. Claims of secured lenders with respect to assets securing their loans will have priority over any claim of the holders of the New Notes with respect to those assets. See “Description of the New Notes—Ranking.”

An active trading market may not develop for the New Notes.

The New Notes constitute a new issue of securities with no established trading market. We do not intend to apply for listing of the New Notes on any national securities exchange or for inclusion of the New Notes on any automated dealer quotation system. Holders of Old Notes have no obligation to exchange their Old Notes for New Notes, and the exchange offer does not impose a condition regarding the minimum aggregate principal amount of Old Notes that must be tendered for exchange in order for the exchange offer to proceed. Accordingly, we cannot predict the aggregate principal amount of New Notes that we will issue in the exchange offer, and that aggregate principal amount might be small. We cannot ensure the liquidity of any trading market for the New Notes or that an active public market for the New Notes will develop. If an active public trading market for the New Notes does not develop, the market price and liquidity of the New Notes will be adversely affected. If the New Notes are traded, they may trade at a discount from their initial issuance price, depending on prevailing interest rates, the market for similar securities, our operating performance and financial condition, general economic conditions and other factors.

Changes in our credit ratings or the debt markets could adversely affect the trading price of the New Notes.

The trading price for the New Notes will depend on many factors, including:

The condition of the financial markets and prevailing interest rates have fluctuated significantly in the past and are likely to fluctuate in the future. Such fluctuations could have an adverse effect on the trading prices of the New Notes.

In addition, credit rating agencies continually review their ratings for the companies that they follow, including us. A negative change in our rating could have an adverse effect on the trading price of the New Notes.

Risks Related to the Exchange Offer

If you fail to exchange your Old Notes, they will continue to be restricted securities and may become less liquid.

After the exchange offer, any Old Notes that you do not tender or that we do not accept will remain restricted securities and may not be offered or sold except pursuant to an exemption from, or in a transaction not subject to, the registration requirements of the Securities Act and applicable state securities laws.

10

If a large aggregate principal amount of Old Notes are exchanged for New Notes in the exchange offer, we expect that the liquidity of the market for any Old Notes remaining after the exchange offer will be substantially limited. Any Old Notes tendered and exchanged in the exchange offer will reduce the aggregate principal amount of the Old Notes outstanding. After the exchange offer, if you do not tender your Old Notes, you generally will not have any further registration rights, and your Old Notes will continue to be subject to certain transfer restrictions. Accordingly, the liquidity of the market for the Old Notes could be adversely affected.

Late deliveries of Old Notes and other required documents could prevent a holder from exchanging its Old Notes.

Holders are responsible for complying with all exchange offer procedures. The issuance of New Notes in exchange for Old Notes will only occur upon completion of the procedures described in this prospectus under “The Exchange Offer.” Therefore, holders of Old Notes who wish to exchange them for New Notes should allow sufficient time for timely completion of the exchange offer procedures. Neither we nor the exchange agent are obligated to extend the offer or notify you of any failure to follow the proper procedures or waive any defect if you fail to follow the proper procedures.

If you are a broker-dealer, your ability to transfer the New Notes may be restricted.

A broker-dealer that purchased Old Notes for its own account as part of market-making or trading activities must comply with the prospectus delivery requirements of the Securities Act when it sells the New Notes. Our obligation to make this prospectus available to broker-dealers is limited. Consequently, we cannot guarantee that a proper prospectus will be available to broker-dealers wishing to resell their New Notes. See “Plan of Distribution.”

Some holders who exchange their Old Notes may be deemed to be underwriters, and these holders will be required to comply with the registration and prospectus delivery requirements in connection with any resale transaction.

Some holders who exchange their Old Notes in the exchange offer for the purpose of participating in a distribution of the Old Notes may be deemed to have received securities that are not freely transferable and, if so, will be required to comply with the registration and prospectus delivery requirements of the Securities Act in connection with any resale transaction.

Each statement speaks only as of the date of this prospectus or, in the case of the documents incorporated by reference, the date of the applicable document (or any earlier date indicated in the statement). Unless required by law, we undertake no obligation to update or revise any of these statements, whether as a result of new information, future developments or otherwise.

THE EXCHANGE OFFER

Pursuant to the Registration Rights Agreement (as defined below), we agreed to prepare and file with the SEC a registration statement on an appropriate form under the Securities Act with respect to a proposed offer to the holders of the Old Notes (CUSIP Nos. 09062X AJ2 and U0901X AA2 and ISIN Nos. US09062XAJ28 and USU0901XAA29) to issue and deliver to such holders of Old Notes, in exchange for their Old Notes, a like aggregate principal amount of New Notes (CUSIP No. 09062X AK9 and ISIN No. US09062XAK90) that are identical in all material respects to the Old Notes, except for certain transfer restrictions on the Old Notes, provisions relating to additional interest, provisions relating to registration rights and certain other differences described below. See “Registration Rights.”

General

On February 16, 2021, pursuant to exemptions from the registration requirements of the Securities Act, we consummated a private offer to exchange (the “private exchange”) any and all of our outstanding 5.200% Senior Notes due 2045 for Old Notes and cash. We issued $700,731,000 aggregate principal amount of Old Notes in the private exchange.

In connection with the private exchange, we entered into the Registration Rights Agreement (the “Registration Rights Agreement”) with Deutsche Bank Securities Inc. and Citigroup Global Markets Inc., as dealer managers for the private exchange. Pursuant to the Registration Rights Agreement, we agreed that (1) we would use commercially reasonable efforts to consummate an exchange offer to exchange the Old Notes for registered notes containing terms substantially identical to the Old Notes, except that the offer and exchange of the New Notes are registered under the Securities Act, and the New Notes generally have no transfer restrictions, rights to additional interest or registration rights, and evidencing the same indebtedness as the Old Notes and (2) if we determine that a registered exchange offer is not available or other specified circumstances occur, we would use commercially reasonable efforts to have a shelf registration statement declared effective providing for resales of the Old Notes. If we fail to satisfy the foregoing obligations under the Registration Rights Agreement within 365 days of the issue date of the Old Notes, we will be required to pay additional interest to the holders of the Old Notes under certain circumstances.

Terms of the Exchange Offer; Period for Tendering Old Notes

This prospectus and the accompanying letter of transmittal (the “letter of transmittal”) contain the terms and conditions of the exchange offer (together, the “exchange offer”). Upon the terms and subject to the conditions included in this prospectus and the letter of transmittal, we will accept for exchange Old Notes which are properly tendered on or before 5:00 p.m., New York City time, on                , 2022, unless extended (the “expiration date”), unless you have previously withdrawn them. No alternative, conditional or contingent tenders will be accepted.

When you tender Old Notes as provided below, our acceptance of the Old Notes will constitute a binding agreement between you and us upon the terms and subject to the conditions in this prospectus and the letter of transmittal. In tendering Old Notes, you should note the following important information:

15

Procedures for Tendering Old Notes

What to Submit and How

If you, as a holder of any Old Notes, wish to tender your Old Notes for exchange in the exchange offer, then on or before the expiration date:

(1) You must transmit to the exchange agent either:

(a) if Old Notes are tendered in accordance with the book-entry procedures described under “—Book-Entry Transfer,” an agent’s message, as defined below, through the automatic tender offer program (“ATOP”) of The Depository Trust Company (“DTC”), or

(b) a properly completed and duly executed letter of transmittal, or a facsimile copy thereof, to the exchange agent’s address set forth below under “—Exchange Agent,” including all other documents required by the letter of transmittal;

and, in each case,

(2) you must timely send, and the exchange agent must actually receive timely confirmation of, a book-entry transfer of Old Notes into the exchange agent’s account at DTC using the procedure for book-entry transfer described under “—Book-Entry Transfer” (a “book-entry confirmation”).

The term “agent’s message” means a message, transmitted through ATOP by DTC, to, and received by, the exchange agent and forming a part of a book-entry confirmation, that states that DTC has received an express acknowledgement that the tendering holder has received and agrees to be bound by the letter of transmittal and that we may enforce the letter of transmittal against such holder.

If you are a beneficial owner whose Old Notes are registered in the name of a broker, dealer, commercial bank, trust company or other nominee and wish to tender your Old Notes, you should promptly instruct the registered holder to tender such Old Notes on your behalf and comply with the ATOP procedures for book-entry transfer described under “—Book-Entry Transfer” on or before the expiration date.

The method of delivery of Old Notes, letters of transmittal and all other required documentation, including delivery of Old Notes through book-entry transfer and transmission of agent’s messages through DTC’s ATOP, is at your election and risk. Delivery will be deemed made only when all required documentation is actually received by the exchange agent. Delivery of documents or instructions to DTC does not constitute delivery to the exchange agent. If delivery is by mail, we recommend that registered mail, properly insured, with return receipt requested, be used. In all cases, sufficient time should be allowed to assure timely delivery to the exchange agent. Holders tendering Old Notes or transmitting agent’s messages through DTC’s ATOP must allow sufficient time for completion of ATOP procedures during DTC’s normal business hours. No Old Notes, agent’s messages, letters of transmittal or any other required documentation should be sent to us.

16

How to Sign Your Letter of Transmittal and Other Documents

Signatures on a letter of transmittal or a notice of withdrawal, as the case may be, must be guaranteed, unless the Old Notes being surrendered for exchange are tendered:

If signatures on a letter of transmittal or a notice of withdrawal, as the case may be, are required to be guaranteed, the guarantees must be by an eligible institution.

If the letter of transmittal is signed by a person or persons other than the registered holder or holders of Old Notes, the Old Notes must be endorsed or accompanied by appropriate powers of attorney, in either case signed exactly as the name or names of the registered holder or holders appear on the Old Notes and with the signatures guaranteed.

If the letter of transmittal or any Old Notes or powers of attorney are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, the person should so indicate when signing and, unless waived by us, proper evidence satisfactory to us of such person’s authority to so act must be submitted.

Acceptance of Old Notes for Exchange; Delivery of New Notes

Once all of the conditions to the exchange offer are satisfied or waived, we will accept all Old Notes properly tendered and not properly withdrawn, and will issue the New Notes, promptly after the expiration date. See “—Conditions to the Exchange Offer” below. For purposes of the exchange offer, our giving of oral (promptly followed in writing) or written notice of acceptance to the exchange agent will be considered our acceptance of the tendered Old Notes.

In all cases, we will issue New Notes in exchange for Old Notes that are accepted for exchange only after timely receipt by the exchange agent of:

If we do not accept any tendered Old Notes for any reason included in the terms and conditions of the exchange offer, we will return any unaccepted, non-exchanged or properly withdrawn Old Notes, as the case may be, without expense to the tendering holder. In the case of Old Notes tendered by book-entry transfer into the exchange agent’s account at DTC using the book-entry transfer procedures described below, unaccepted, non-exchanged or properly withdrawn Old Notes will be credited to an account maintained with DTC. We will have the Old Notes credited to the DTC account promptly after the expiration or termination of the exchange offer.

17

Book-Entry Transfer

The exchange agent will make a request to establish an account with respect to the Old Notes at DTC for purposes of the exchange offer promptly after the date of this prospectus. Any financial institution that is a participant in DTC’s systems, including Euroclear Bank, S.A./N.V., as operator of the Euroclear System (“Euroclear”), or Clearstream Luxembourg, société anonyme (“Clearstream Luxembourg”), may make book-entry delivery of Old Notes by causing DTC to transfer Old Notes into the exchange agent’s account at DTC in accordance with DTC’s ATOP procedures for transfer. However, the exchange for the Old Notes so tendered will only be made after timely confirmation of book-entry transfer of Old Notes into the exchange agent’s account, and timely receipt by the exchange agent of an agent’s message and all other documents required by the letter of transmittal. Only participants in DTC may deliver Old Notes by book-entry transfer.

Although delivery of Old Notes may be effected through book-entry transfer into the exchange agent’s account at DTC, the letter of transmittal, or a facsimile copy thereof, properly completed and duly executed, with any required signature guarantees, or an agent’s message, with all other required documentation, must in any case be transmitted to and received by the exchange agent at its address listed under “—Exchange Agent” on or before the expiration date. Please note that delivery of documents or instructions to DTC does not constitute delivery to the exchange agent, and we will not be able to accept your tender of Old Notes until the exchange agent actually receives from DTC the information and documentation described under “—Acceptance of Old Notes for Exchange; Delivery of New Notes.”

Withdrawal Rights

You can withdraw your tender of Old Notes at any time on or before 5:00 p.m., New York City time, on the expiration date.

For a withdrawal to be effective, a written notice of withdrawal must be actually received by the exchange agent before such time, properly transmitted either through DTC’s ATOP or to the exchange agent at the address listed below under “—Exchange Agent.” Any notice of withdrawal must:

Please note that all questions as to the validity, form, eligibility and time of receipt of notices of withdrawal will be determined by us, and our determination shall be final and binding on all parties. Any Old Notes so withdrawn will be considered not to have been properly tendered for exchange for purposes of the exchange offer. New Notes will not be issued in exchange for such withdrawn Old Notes unless the Old Notes so withdrawn are properly re-tendered.

If you have properly withdrawn Old Notes and wish to re-tender them, you may do so by following one of the procedures described under “—Procedures for Tendering Old Notes” above at any time on or before the expiration date.

18

Any Old Notes that have been tendered for exchange, but which are not exchanged for any reason, will be credited to an account maintained with DTC for the Old Notes promptly after withdrawal, rejection of tender or termination of the exchange offer.

Conditions to the Exchange Offer

Notwithstanding any other provisions of the exchange offer, we will not be required to accept for exchange, or to issue New Notes in exchange for, any Old Notes and may terminate or amend the exchange offer, if we determine in our reasonable judgment at any time before the expiration date that:

The foregoing conditions are for our sole benefit and may be waived by us regardless of the circumstances giving rise to any condition. Our failure at any time to exercise the foregoing rights shall not be considered a waiver by us of that right. The rights described in the prior paragraph are ongoing rights which we may assert at any time and from time to time.

In addition, we will not accept for exchange any Old Notes tendered, and no New Notes will be issued in exchange for any such Old Notes, if at any time any stop order is threatened or in effect with respect to the

19

registration statement of which this prospectus constitutes a part or the qualification of the indenture under the Trust Indenture Act of 1939, as amended (the “Trust Indenture Act”).

We reserve the right to terminate or amend the exchange offer at any time before the expiration date upon the occurrence of any of the foregoing events.

Exchange Agent

Global Bondholder Services Corporation has been appointed as the exchange agent for the exchange offer. All executed letters of transmittal, notices of withdrawal and any other required documentation should be directed to the exchange agent at the address set forth below. Questions and requests for assistance, requests for additional copies of this prospectus or of the letter of transmittal should be directed to the exchange agent, addressed as follows:

By Regular, Registered or Certified Mail,

By Overnight Courier or By Hand:

Delivery to an address other than the address of the exchange agent as listed above or transmission of instructions via facsimile other than as listed above does not constitute a valid delivery.

Fees and Expenses

The principal solicitation is being made by mail; however, additional solicitation may be made by facsimile, email, telephone or in person by our officers, regular employees or affiliates. We will not pay any additional compensation to any of our officers or employees who engage in soliciting tenders. We will not make any payment to brokers, dealers or others soliciting acceptances of the exchange offer. However, we will pay the exchange agent reasonable and customary fees for its services and will reimburse it for its reasonable out-of-pocket expenses in connection with the exchange offer.

The expenses to be incurred in connection with the exchange offer, including legal, accounting, SEC filing, printing and exchange agent expenses, will be paid by us.

Accounting Treatment

We will record the New Notes at the same carrying value as the Old Notes, as reflected in our accounting records on the date of the exchange. Accordingly, we will not recognize any gain or loss for accounting purposes. Payments made to third parties in connection with the exchange offer will be expensed as incurred in accordance with U.S. generally accepted accounting principles.

Transfer Taxes

Holders who tender their Old Notes for exchange will not be obligated to pay any transfer taxes in connection therewith, except that holders who instruct us to register New Notes in the name of, or request that Old Notes not tendered or not accepted in the exchange offer be returned to, a person other than the registered tendering holder will be responsible for the payment of any applicable transfer tax.

20

Resale of the New Notes

Under existing interpretations of the staff of the SEC contained in several no-action letters to third parties, the New Notes would in general be freely transferable by holders thereof, other than our affiliates (as defined below), after the exchange offer without further registration under the Securities Act (subject to certain representations required to be made by each holder of Old Notes participating in the exchange offer, as set forth below). The relevant no-action letters include the Exxon Capital Holdings Corporation letter, which was made available by the SEC on May 13, 1988, the Morgan Stanley & Co. Incorporated letter, which was made available by the SEC on June 5, 1991, the K-III Communications Corporation letter, which was made available by the SEC on May 14, 1993, and the Shearman & Sterling letter, which was made available by the SEC on July 2, 1993. We have not entered into any arrangement or understanding with any person who will receive New Notes in the exchange offer to distribute those securities following completion of the exchange offer. To our knowledge, each person eligible to participate in the exchange offer is (i) neither an affiliate of ours within the meaning of Rule 405 under the Securities Act (an “affiliate”), nor a broker-dealer acquiring New Notes in exchange for Old Notes acquired directly from us for its own account, (ii) acquiring New Notes in the ordinary course of its business, and (iii) is not engaged in, and does not intend to engage in, a distribution of the New Notes to be received in the exchange offer and has no arrangement or understanding with any person to participate in the distribution of the New Notes to be received in the exchange offer.

However, any person participating in the exchange offer who is an affiliate of ours, who is not acquiring New Notes in the ordinary course of its business or who intends to acquire New Notes for the purpose of distributing them:

We acknowledge that such secondary resale transactions should be covered by an effective registration statement containing the selling security holder information required by Item 507 of Regulation S-K promulgated under the Securities Act.

By executing, or otherwise becoming bound by, the letter of transmittal, each tendering holder of Old Notes will generally represent that:

We have not sought, and do not intend to seek, a no-action letter from the SEC with respect to the effects of the exchange offer, and there can be no assurance that the SEC staff would make a similar determination with respect to the New Notes as it has made in previous no-action letters.

In addition, in connection with any resales of New Notes acquired in the exchange offer, any broker-dealer receiving New Notes for its own account in exchange for Old Notes acquired by such broker-dealer as a result of market-making activities or other trading activities must acknowledge that it may be a statutory underwriter and that it must deliver a prospectus meeting the requirements of the Securities Act to purchasers in connection with

21

any resale of such New Notes. See “Plan of Distribution.” By making such acknowledgement and delivering such a prospectus in connection with any such resale, a broker-dealer does not thereby admit that it is an underwriter within the meaning of the Securities Act with respect to such resale.

The SEC has taken the position in the Shearman & Sterling no-action letter, which it made available on July 2, 1993, that broker-dealers may fulfill their prospectus delivery requirements with respect to the New Notes, other than a resale of New Notes received in exchange for an unsold allotment from the original sale of the Old Notes, by delivery of the prospectus contained in the exchange offer registration statement.

22

USE OF PROCEEDS

The exchange offer is intended to satisfy our obligations under the Registration Rights Agreement we entered into in connection with the private exchange of the Old Notes. We will not receive any cash proceeds from the issuance of the New Notes under the exchange offer. In consideration for issuing the New Notes as contemplated by this prospectus, we will receive Old Notes in like principal amounts, the terms of which are identical in all material respects to the New Notes, subject to limited exceptions. Old Notes surrendered in exchange for New Notes will be retired and canceled and cannot be reissued. Accordingly, the issuance of the New Notes will not result in any increase in our indebtedness.

23

DESCRIPTION OF THE NEW NOTES

The Old Notes were issued on February 16, 2021 in a private exchange offer exempt from the registration requirements of the Securities Act.

The New Notes are a series of debt securities to be issued under an indenture, dated as of September 15, 2015, between the Company and U.S. Bank Trust Company, National Association (as successor in interest to U.S. Bank National Association), as trustee, as supplemented by the supplemental indenture under which the Old Notes were also issued on February 16, 2021, between the Company and the trustee. We refer to this indenture, as so supplemented, as the “indenture.” The terms of the New Notes include those stated in the indenture and those made part of the indenture by reference to the Trust Indenture Act. A copy of the indenture is available for inspection at the corporate trust office of the trustee.

The New Notes will be treated as a single class with any Old Notes that remain outstanding after the completion of the exchange offer. In determining whether holders of the requisite percentage of aggregate principal amount of debt securities of a series have given any notice, consent or waiver or taken any other action permitted under the indenture, any Old Notes that remain outstanding after the completion of the exchange offer will be aggregated with the New Notes, and the holders of these Old Notes and New Notes will vote together as a single class for all such purposes. Accordingly, all references in this “Description of the New Notes” to specified percentages in aggregate principal amount of outstanding notes mean, at any time after the completion of the exchange offer, such percentage in aggregate principal amount of the Old Notes and the New Notes then outstanding. We refer to the New Notes and any Old Notes outstanding after the completion of the exchange offer as the “Notes.”

As used in this “Description of the New Notes,” the terms “the Company,” “we,” “our,” “us” and other similar references refer only to Biogen Inc. and not to any of its subsidiaries.

General

There will be no accrued interest paid on the settlement date of the exchange offer. The Notes will mature and become due and payable, together with any accrued and unpaid interest thereon, on February 15, 2051. Interest will be payable semiannually on February 15 and August 15 of each year, beginning August 15, 2021 (or, if later, the first interest payment date after issuance of the New Notes). Interest on the Notes will be paid to holders of record at the close of business on February 1 or August 1, whether or not a business day, immediately before the applicable interest payment date. The amount of interest payable on the Notes will be computed on the basis of a 360-day year consisting of twelve 30-day months.

The Notes will be issued only in fully registered form, without coupons, in minimum denominations of $2,000 in principal amount and integral multiples of $1,000 in excess thereof.

If any interest payment date or the maturity date of the Notes is not a business day, then the related payment of interest and/or principal payable on such date will be paid on the next succeeding business day with the same force and effect as if made on such interest payment date or maturity date and no further interest will accrue in respect of the delay. The term “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 are authorized or required by law, regulation or executive order to close.

Further Issues

We may from time to time, without notice to or the consent of the holders or beneficial owners of the Notes, create and issue additional notes having the same ranking and the same interest rate, maturity and other terms as the Notes. Any additional notes having such similar terms could be considered part of the same series of notes under the indenture, provided that if the additional notes are not fungible with the Notes for U.S. federal income tax purposes, the additional notes will have a separate CUSIP number.

24

Ranking

The New Notes will be our senior unsecured obligations and will rank equal in right of payment with the Old Notes and our other existing and future senior unsecured obligations that are not, by their terms, expressly subordinated in right of payment to the New Notes, and senior in right of payment to any of our future subordinated indebtedness.

The New Notes will be effectively subordinated to all of our existing and future secured indebtedness and other secured liabilities to the extent of the value of the assets securing such indebtedness and liabilities. The indenture limits the amount of secured indebtedness that we or our Subsidiaries (as defined below) may incur pursuant to the covenant described under the heading “—Limitation on Liens.” This covenant is subject to important exceptions described under such heading. As of March 31, 2022, we had no secured debt outstanding.

We conduct substantially all of our operations through subsidiaries, which generate a substantial portion of our operating income and cash. As a result, distributions or advances from our subsidiaries are a major source of funds necessary to meet our debt service and other obligations. Contractual provisions, laws or regulations, as well as any subsidiary’s financial condition and operating requirements, may limit our ability to obtain cash required to service our debt obligations, including making payments on the Notes.

The New Notes will be structurally subordinated to all existing and future obligations of our subsidiaries, including claims with respect to trade payables. This means that holders of the New Notes will have a junior position to the claims of creditors of our direct and indirect subsidiaries on the assets and earnings of such subsidiaries. The indenture does not limit the amount of debt that our subsidiaries are permitted to incur. As of March 31, 2022, neither we nor our subsidiaries had any secured debt outstanding, and our subsidiaries had total liabilities of approximately $5.3 billion.

Optional Redemption

At any time prior to the Par Call Date (as defined below), from time to time, the Notes are redeemable, as a whole or in part, at our option, on at least 10 days, but not more than 60 days, prior notice mailed to the registered address of each holder of the Notes to be redeemed (or otherwise delivered in accordance with the applicable procedures of DTC), at a redemption price equal to the greater of:

plus accrued and unpaid interest to, but not including, the date of redemption.

In addition, at any time on or after the Par Call Date, the Notes may be redeemed, as a whole or in part, at our option, on at least 10 days, but not more than 60 days, prior notice mailed to the registered address of each holder of the Notes to be redeemed (or otherwise delivered in accordance with the applicable procedures of DTC), at a redemption price equal to 100% of the principal amount of the Notes to be redeemed on the redemption date plus accrued and unpaid interest to, but not including, the date of redemption.

“Comparable Treasury Issue” means the U.S. Treasury security or securities selected by an Independent Investment Banker (as defined below) as having an actual or interpolated maturity comparable to the remaining term of the Notes (“Remaining Life”) to be redeemed that would be utilized, at the time of selection and in accordance with customary financial practice, in pricing new issues of corporate debt securities of a comparable maturity to the remaining term of the Notes.

25

“Comparable Treasury Price” means, with respect to any Notes on any redemption date, (A) the average of the Reference Treasury Dealer Quotations (as defined below) for such redemption date, after excluding the highest and lowest such Reference Treasury Dealer Quotations, or (B) if the Independent Investment Banker obtains fewer than four such Reference Treasury Dealer Quotations, the average of all such quotations.

“Independent Investment Banker” means one of the Reference Treasury Dealers (as defined below) appointed by us.

“Par Call Date” means August 15, 2050 (six months prior to the maturity date of the Notes).

“Reference Treasury Dealer” means each of Deutsche Bank Securities Inc. and Citigroup Global Markets Inc. or their respective affiliates, which are primary U.S. Government securities dealers in The City of New York, and their respective successors plus three other primary U.S. Government securities dealers in The City of New York selected by us; provided, however, that if any of the foregoing or their affiliates shall cease to be a primary U.S. Government securities dealer in The City of New York (a “Primary Treasury Dealer”), we will substitute therefor another Primary Treasury Dealer.

“Reference Treasury Dealer Quotations” means, with respect to each Reference Treasury Dealer and any redemption date, the average, as determined by the Independent Investment Banker, of the bid and asked prices for the applicable Comparable Treasury Issue (expressed in each case as a percentage of its principal amount) quoted in writing to the Independent Investment Banker by the Reference Treasury Dealers at 3:30 p.m. New York time on the third business day preceding such redemption date.

“Treasury Rate” means, with respect to a redemption date: (1) the rate per annum equal to the yield, under the heading which represents the average for the immediately preceding week, appearing in the most recently published statistical release designated “H.15(519)” or any successor publication which is published weekly by the Board of Governors of the Federal Reserve System and which establishes yields on actively traded U.S. Treasury securities adjusted to constant maturity under the caption “Treasury Constant Maturities” for the maturity corresponding to the Comparable Treasury Issue; provided that, if no maturity is within three months before or after the Remaining Life of the Notes to be redeemed, yields for the two published maturities most closely corresponding to the Comparable Treasury Issue shall be determined and the Treasury Rate shall be interpolated or extrapolated from those yields on a straight-line basis, rounding to the nearest month; or (2) if such release (or any successor release) is not published during the week preceding the calculation date or does not contain such yields, the rate per year equal to the semiannual equivalent yield to maturity or interpolated (on a day count basis) of the Comparable Treasury Issue, assuming a price for the applicable Comparable Treasury Issue (expressed as a percentage of its principal amount) equal to the applicable Comparable Treasury Price for such redemption date. The Treasury Rate shall be calculated on the third business day preceding the redemption date.

On and after the redemption date, interest will cease to accrue on the Notes or any portion thereof called for redemption, unless we default in the payment of the redemption price. On or before the redemption date, we will deposit with a paying agent, or the trustee, funds sufficient to pay the redemption price of and accrued and unpaid interest on the Notes to be redeemed on such date. If less than all of the Notes are to be redeemed, the Notes to be redeemed will be selected by DTC in accordance with its standard procedures. If the Notes to be redeemed are not global notes then held by DTC, or DTC prescribes no method of selection, the trustee will select the Notes to be redeemed on a pro rata basis, by lot, or by any other method the trustee deems fair and appropriate and subject to and otherwise in accordance with the procedures of DTC. Any redemption or notice of redemption may, at our discretion, be subject to one or more conditions precedent, and, at our discretion, the redemption date may be delayed until such time as any or all such conditions shall be satisfied. We will provide written notice to the trustee prior to the close of business two business days prior to the redemption date if any such redemption has been rescinded or delayed, and upon receipt the trustee shall provide such notice to each holder of the Notes in the same manner in which the notice of redemption was given.

26

Change of Control

If a Change of Control Triggering Event occurs, unless we have exercised our option to redeem the Notes as described above, we will be required to make an offer (the “Change of Control Offer”) to each holder of the Notes to repurchase all or any part (equal to $2,000 in principal amount or an integral multiple of $1,000 in excess thereof) of that holder’s Notes on the terms set forth in the Notes. In the Change of Control Offer, we will be required to offer payment in cash equal to 101% of the aggregate principal amount of Notes repurchased, plus accrued and unpaid interest, if any, on the Notes repurchased to but not including the date of repurchase (the “Change of Control Payment”). Within 30 days following any Change of Control Triggering Event or, at our 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 DTC) to holders of the Notes describing the transaction that constitutes or may constitute the Change of Control Triggering Event and offering to repurchase 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 DTC) 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, we will, to the extent lawful:

We will 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 us and the third party repurchases all Notes properly tendered and not withdrawn under its offer. In addition, we will not repurchase any Notes if there has occurred and is continuing on the Change of Control Payment Date an event of default under the indenture, other than a default in the payment of the Change of Control Payment upon a Change of Control Triggering Event.

We will comply 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 repurchase 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, we will comply with those securities laws and regulations and will not be deemed to have breached our obligations under the Change of Control Offer provisions of the New Notes by virtue of any such conflict.

For purposes of the Change of Control Offer provisions of the Notes, the following terms will be 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 us or one of our 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 our Voting Stock (as defined below) or other Voting Stock into which our Voting Stock is reclassified, consolidated, exchanged or changed, measured by voting power rather than number of shares; provided,

27

however, that a Person (as defined below) shall not be deemed 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 our assets and the assets of our 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 us or one of our 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 our 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; (3) we consolidate with, or merge 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, us, in either case, pursuant to a transaction in which any of our 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 our 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 immediately after giving effect to such transaction; or (4) the adoption of a plan relating to our liquidation or dissolution.

“Change of Control Triggering Event” means the occurrence of both a Change of Control and a Rating Event (as defined below).

“Fitch” means Fitch Inc., or any successor thereto.

“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 Fitch, and the equivalent investment grade credit rating from any additional rating agency or Rating Agencies (as defined below) selected by the Company.

“Moody’s” means Moody’s Investors Service, Inc., or any successor thereto.

“Rating Agencies” means (1) each of Fitch, Moody’s and S&P and (2) if any of Fitch, 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 our control, a “nationally recognized statistical rating organization” within the meaning of Section 3(a)(62) of the Exchange Act selected by us (as certified by a resolution of our board of directors) and which is reasonably acceptable to the trustee as a replacement agency for Fitch, Moody’s or S&P, or all of them, as the case may be.

“Rating Event” means the rating on the Notes is lowered by at least two of the three Rating Agencies and the Notes are rated below an Investment Grade Rating by at least two of the three Rating Agencies, 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 our 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 Standard & Poor’s Ratings Services, a Standard & Poor’s Financial Services LLC business, 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.

28

The definition of Change of Control includes a phrase relating to the direct or indirect sale, lease, transfer, conveyance or other disposition of “all or substantially all” of our assets and the assets of our Subsidiaries, taken as a whole. Although there is a limited body of case law interpreting the phrase “substantially all,” there is no precise, established definition of the phrase under applicable law. Accordingly, the applicability of the requirement that we offer to repurchase the Notes as a result of the sale, lease, transfer, conveyance or other disposition of less than all of our assets and the assets of our 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 us or one of our Subsidiaries) may be uncertain.

Sinking Fund

The Notes will not be entitled to the benefit of any sinking fund.

Limitation on Liens

Other than as provided under “—Exempted Liens and Sale and Leaseback Transactions,” we will not, and will not permit any Subsidiary of ours to, create or assume any Indebtedness secured by any Lien on any of our or their respective Properties unless the Notes are secured by such Lien equally and ratably with, or prior to, the Indebtedness secured by such Lien. This restriction does not apply to Indebtedness that is secured by:

29

Limitation on Sale and Leaseback Transactions

Other than as provided under “—Exempted Liens and Sale and Leaseback Transactions,” we will not, and will not permit any of our Subsidiaries to, enter into any Sale and Leaseback Transaction with respect to any of our or their respective Properties, the acquisition or completion of construction and commencement of full operations of which has occurred more than 270 days prior thereto, unless:

30

Exempted Liens and Sale and Leaseback Transactions

Notwithstanding the restrictions described under the headings “—Limitation on Liens” or “—Limitation on Sale and Leaseback Transactions,” we or any Subsidiary of ours may create or assume any Liens or enter into any Sale and Leaseback Transactions not otherwise permitted as described above, if the sum of the following does not exceed 10% of Consolidated Total Assets (as defined below):

measured, in each case, at the time such Lien is incurred or any such Sale and Leaseback Transaction is entered into by us or such Subsidiary of ours.

Merger, Consolidation or Sale of Assets

We may merge or consolidate with another Person and may sell, transfer or lease all or substantially all of our assets to another Person if all the following conditions are met:

Events of Default

The term “event of default” means any of the following:

31

If an event of default (other than due to certain events in bankruptcy, insolvency or reorganization) has occurred and has not been cured, the trustee or the holders of at least 25% in aggregate principal amount of the Notes may, by a notice in writing to us (and to the trustee if given by the holders), declare the entire principal amount (and premium, if any) of, and all the accrued and unpaid interest on the Notes to be due and immediately payable. This is called a declaration of acceleration of maturity. If an event of default occurs because of certain events in bankruptcy, insolvency or reorganization relating to us, the principal amount of the Notes will be automatically accelerated, without any action by the trustee or any holder. Holders of a majority in aggregate principal amount of the Notes may also waive certain past defaults under the indenture on behalf of all of the holders of the Notes. A declaration of acceleration of maturity may be canceled, under specific circumstances, by the holders of at least a majority in aggregate principal amount of the Notes.

If any securities are outstanding under the indenture, the indenture requires us, within 120 days after the end of each fiscal year, to furnish to the trustee a statement as to our compliance with the indenture. The trustee will generally give the holders of Notes notice within 90 days of the occurrence of an event of default known to the trustee.

Except in cases of default, where the trustee has some special duties, the trustee is not required to take any action under the indenture at the request of any of the holders unless the holders offer the trustee indemnity and/or security satisfactory to it. If indemnity and/or security satisfactory to the trustee is provided, the holders of a majority in aggregate principal amount of the Notes may direct the time, method and place of conducting any lawsuit or other formal legal action seeking any remedy available to the trustee. The trustee may refuse to follow those directions in certain circumstances. No delay or omission in exercising any right or remedy will be treated as a waiver of the right, remedy or event of default.

Before you are allowed to bypass the trustee and bring a lawsuit or other formal legal action or take other steps to enforce your rights or protect your interests relating to the Notes, the following must occur:

However, you are entitled at any time to bring a lawsuit for the payment of money due on your Notes on or after the due date.

Defeasance

Full Defeasance. If the Internal Revenue Service (the “IRS”) issues a ruling or there is a change in applicable U.S. federal tax law, as described below, we can legally release ourselves from any payment or other

32

obligations on the Notes, called “full defeasance,” if we put in place the following other arrangements for you to be repaid:

If we accomplish full defeasance, as described above, you would have to rely solely on the trust deposit for repayment on the Notes. You could not look to us for repayment in the unlikely event of any shortfall. Conversely, the trust deposit would most likely be protected from claims of our lenders and other creditors if we ever become bankrupt or insolvent.

Covenant Defeasance. We can be released from the restrictive covenants in the Notes if we make the arrangements described below. This is called “covenant defeasance.” In that event, you would lose the protection of those restrictive covenants but would gain the protection of having money and securities set aside in trust to repay the Notes. In order to achieve covenant defeasance, we must do the following:

If we accomplish covenant defeasance, the following provisions of the indenture and the Notes would no longer apply unless otherwise specified:

If we accomplish covenant defeasance, you can still look to us for repayment of the Notes if there were a shortfall in the trust deposit. In fact, if one of the remaining events of default occurred (such as our bankruptcy) and the Notes become immediately due and payable, there may be such a shortfall. Depending on the event causing the default, of course, you may not be able to obtain payment of the shortfall.

In order to exercise either full defeasance or covenant defeasance, we must comply with certain conditions, and no event or condition can exist that would prevent us from making payments of principal, premium and interest, if any, on the Notes on the date the irrevocable deposit is made or at any time during the period ending on the 91st day after the deposit date.

Notices

With respect to the Notes, we and the trustee will send notices regarding the Notes only to registered holders, using their addresses as listed in the list of registered holders.

33

Modification or Waiver

We generally may modify and amend the indenture with respect to the Notes with the consent of the holders of at least a majority in aggregate principal amount of the outstanding Notes. However, we may not make any modification or amendment without the consent of each holder of the Notes if such action would:

Except for certain specified provisions, the holders of at least a majority in aggregate principal amount of the outstanding Notes may, on behalf of the holders of all the Notes, waive our compliance with certain provisions of the indenture. The holders of a majority in aggregate principal amount of the outstanding Notes may, on behalf of the holders of all the Notes, waive any past default under the indenture and its consequences, except a default in the payment of the principal of or premium or interest on any Notes or in respect of a covenant or provision which cannot be modified or amended without the consent of the holder of each outstanding note; provided, however, that the holders of a majority in aggregate principal amount of the outstanding Notes may rescind an acceleration and its consequences, including any payment default that resulted from such acceleration.

Notwithstanding the foregoing, without the consent of any holder of Notes, we may amend or supplement the indenture or the Notes to, among other reasons:

34

Satisfaction and Discharge

The indenture will cease to be of further effect, and we will be deemed to have satisfied and discharged the indenture with respect to the Notes, when the following conditions have been satisfied:

We will remain obligated to provide for registration of transfer and exchange and to provide notices of redemption.

SEC Reports

We will file with the trustee, within 15 days after we are required to file the same with the SEC, copies of the annual reports and of the information, documents and other reports (or copies of such portions of any of the foregoing as the SEC may prescribe) that we may be required to file with the SEC pursuant to Section 13 or Section 15(d) of the Exchange Act; provided that availability of such reports on a website maintained by the SEC shall be deemed to fulfill this requirement. If we are not required to file information, documents or reports pursuant to either of those sections, then we will file with the trustee and the SEC such reports as may be prescribed by the SEC at such time.

The Trustee

The trustee for the New Notes will be U.S. Bank Trust Company, National Association. U.S. Bank Trust Company, National Association also will be the initial paying agent and registrar for the New Notes.

The indenture provides that, except during the continuance of an event of default under the indenture, the trustee under the indenture will perform only such duties as are specifically set forth in the indenture. Under the indenture, the holders of a majority in outstanding aggregate principal amount of the Notes will have the right to direct the time, method and place of conducting any proceeding or exercising any remedy available to the trustee under the indenture, subject to certain exceptions. If an event of default has occurred and is continuing, the trustee under the indenture will exercise such rights and powers vested in it under the indenture and is obligated to use the same degree of care and skill in its exercise as a prudent person would exercise under the circumstances in the conduct of such person’s own affairs.

The indenture and provisions of the Trust Indenture Act incorporated by reference in the indenture contain limitations on the rights of the trustee under such indenture, should it become a creditor of our company, to obtain payment of claims in certain cases or to realize on certain property received by it in respect of any such claims, as security or otherwise. The trustee under the indenture is permitted to engage in other transactions. However, if the trustee under the indenture acquires any prohibited conflicting interest, it must eliminate the conflict or resign.

The trustee may resign or be removed and a successor trustee may be appointed.

35

Governing Law

The indenture and the Notes will be governed by, and construed in accordance with, the laws of the State of New York.

The calculation of the present value of the total net amount of rent payments is subject to adjustments specified in the indenture.

“Capitalized Lease” means any obligation of a Person to pay rent or other amounts 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 capital lease in accordance with generally accepted accounting principles.

GLOBAL NOTES; BOOK-ENTRY SYSTEM

The Global Notes

The New Notes will be represented by one or more fully registered global notes, without interest coupons, will be deposited upon issuance with the trustee as custodian for DTC, and registered in the name of Cede & Co. or its nominee, in each case, for credit to an account of a direct or indirect participant as described below.

Except as set forth below, the global notes may be transferred, in whole and not in part, only to another nominee of DTC or to a successor of DTC or its nominee. Beneficial interests in the global notes may not be exchanged for definitive notes in registered certificated form (“certificated notes”) except in the limited circumstances described below. See “—Certain Book Entry Procedures for the Global Notes.”

Transfers of beneficial interests in the global notes are subject to the applicable rules and procedures of DTC and its direct or indirect participants, which may change.

The New Notes may be presented for registration of transfer and exchange at the corporate trust offices of the trustee as set forth in the indenture.

Certain Book Entry Procedures for the New Notes

All interests in the global notes will be subject to the operations and procedures of DTC, Euroclear and Clearstream Luxembourg. The descriptions of the operations and procedures of DTC, Euroclear and Clearstream Luxembourg set forth below are provided solely as a matter of convenience. These operations and procedures are solely within the control of the respective settlement systems and are subject to change by them from time to time. We obtained the information in this section and elsewhere in this prospectus concerning DTC, Euroclear and Clearstream Luxembourg and their respective book-entry systems from sources that we believe are reliable, but we take no responsibility for the accuracy of any of this information, and holders of Old Notes are urged to contact the relevant system or its participants directly to discuss these matters.

DTC. DTC has advised us that it is:

DTC was created to hold securities for its participants (collectively, the “participants”) and to facilitate the clearance and settlement of securities transactions between its participants through electronic book-entry changes to the accounts of its participants, thereby eliminating the need for physical transfer and delivery of certificates. DTC’s participants include securities brokers and dealers, banks and trust companies, clearing corporations and certain other organizations. Indirect access to DTC’s system is also available to other entities such as Clearstream Luxembourg, Euroclear, banks, brokers, dealers and trust companies (collectively, the “indirect participants”) that clear through or maintain a custodial relationship with a participant, either directly or indirectly. Investors who are not participants may beneficially own securities held by or on behalf of DTC only through participants or indirect participants in DTC.

Clearstream Luxembourg. Clearstream Luxembourg is incorporated under the laws of Luxembourg as a professional depositary. Clearstream Luxembourg holds securities for its participating organizations

38

(“Clearstream Luxembourg Participants”) and facilitates the clearance and settlement of securities transactions between Clearstream Luxembourg Participants through electronic book-entry changes in accounts of Clearstream Luxembourg Participants, thereby eliminating the need for physical movement of certificates. Transactions may be settled in Clearstream Luxembourg in any of various currencies, including U.S. dollars. Clearstream Luxembourg provides Clearstream Luxembourg Participants with, among other things, services for safekeeping, administration, clearance and establishment of internationally-traded securities and securities lending and borrowing. Clearstream Luxembourg interfaces with domestic markets in several countries. As a professional depositary, Clearstream Luxembourg is subject to regulation by the Luxembourg Monetary Institute. Clearstream Luxembourg Participants are recognized financial institutions around the world, including underwriters, securities brokers and dealers, banks, trust companies, clearing corporations and certain other organizations. Indirect access to Clearstream Luxembourg is also available to others, such as banks, brokers, dealers and trust companies that clear through or maintain a custodial relationship with a Clearstream Luxembourg Participant either directly or indirectly.

Distributions with respect to New Notes held beneficially through Clearstream Luxembourg will be credited to cash accounts of Clearstream Luxembourg Participants in accordance with its rules and procedures to the extent received by the U.S. depositary for Clearstream Luxembourg.

Euroclear. Euroclear was created in 1968 to hold securities for participants of Euroclear (“Euroclear Participants”) and to clear and settle transactions between Euroclear Participants through simultaneous electronic book-entry delivery against payment, thereby eliminating the need for physical movement of certificates and any risk from lack of simultaneous transfers of securities and cash. Transactions may be settled in any of various currencies, including U.S. dollars. Euroclear includes various other services, including securities lending and borrowing, and interfaces with domestic markets in several markets in several countries. Euroclear is operated by Euroclear Bank S.A./N.V. (the “Euroclear Operator”). All operations are conducted by the Euroclear Operator, and all Euroclear securities clearance accounts and Euroclear cash accounts are accounts with the Euroclear Operator. Euroclear Participants include banks (including central banks), securities brokers and dealers and other professional financial intermediaries. Indirect access to Euroclear is also available to other firms that clear through or maintain a custodial relationship with a Euroclear Participant, either directly or indirectly.

The Euroclear Operator is regulated and examined by the Belgian Banking Commission. Distributions of principal and interest with respect to New Notes held through Euroclear will be credited to the cash accounts of Euroclear Participants in accordance with the relevant system’s rules and procedures, to the extent received by such system’s depositary.

Links have been established among DTC, Clearstream Luxembourg and Euroclear to facilitate the initial issuance of the New Notes and cross-market transfers of the New Notes associated with secondary market trading. DTC will be linked indirectly to Clearstream Luxembourg and Euroclear through the DTC accounts of their respective U.S. depositaries.

Book-Entry Procedures. We expect that, pursuant to procedures established by DTC:

The laws of some jurisdictions may require that some recipients of securities take physical delivery of those securities in definitive form. Accordingly, the ability to transfer beneficial interests in New Notes represented by

39

a global note to those persons may be limited. In addition, because DTC can act only on behalf of its participants, who in turn act on behalf of persons who hold interests through participants, the ability of a Person holding a beneficial interest in a global note to pledge or transfer that interest to persons or entities that do not participate in DTC’s system, or to otherwise take actions in respect of that interest, may be affected by the lack of a physical note in respect of that interest.

So long as DTC or its nominee is the registered owner of a global note, DTC or that nominee, as the case may be, will be considered the sole legal owner or holder of the New Notes represented by that global note for all purposes of the New Notes and the indenture. Except as provided below, owners of beneficial interests in a global note:

Accordingly, each holder owning a beneficial interest in a global note must rely on the procedures of DTC and, if that holder is not a participant or an indirect participant, on the procedures of the participant through which that holder owns its interest, to exercise any rights of a holder of New Notes under the indenture or that global note. We understand that, under existing industry practice, in the event that we request any action of holders of New Notes, or a holder that is an owner of a beneficial interest in a global note desires to take any action that DTC, as the holder of that global note, is entitled to take, DTC would authorize the participants to take that action and the participants would authorize holders owning through those participants to take that action or would otherwise act upon the instruction of those holders. Neither we nor the trustee will have any responsibility or liability for any aspect of the records relating to or payments made on account of New Notes by DTC, or for maintaining, supervising or reviewing any records of DTC relating to the New Notes.

Beneficial interests in the global notes may not be exchanged for certificated notes. However, if DTC notifies us that it is unwilling to be a depositary for the global notes or ceases to be a clearing agency or if we so elect or if there is an event of default under the New Notes, DTC will exchange the global notes for certificated notes which it will distribute to its participants.

Payments with respect to the principal of and interest on a global note will be payable by the trustee to or at the direction of DTC or its nominee in its capacity as the registered holder of the global note under the indenture. Under the terms of the indenture, we and the trustee will treat the persons in whose names the New Notes, including the global notes, are registered as the owners thereof for the purpose of receiving payment thereon and for any and all other purposes whatsoever. Accordingly, neither we nor the trustee has or will have any responsibility or liability for the payment of those amounts to owners of beneficial interests in a global note.

Payments by the participants and the indirect participants to the owners of beneficial interests in a global note will be governed by standing instructions and customary industry practice and will be the responsibility of the participants and indirect participants and not of DTC.

Transfers between participants in DTC will be effected in accordance with DTC’s procedures and will be settled in same-day funds. Transfers between participants in Euroclear or Clearstream Luxembourg will be effected in the ordinary way in accordance with their respective rules and operating procedures.

Cross-market transfers between the participants in DTC, on the one hand, and Euroclear Participants or Clearstream Luxembourg Participants, on the other hand, will be effected through DTC in accordance with DTC’s rules on behalf of Euroclear or Clearstream Luxembourg, as the case may be, by its respective depositary.

40

However, those cross-market transactions will require delivery of instructions to Euroclear or Clearstream Luxembourg, as the case may be, by the counterparty in that system in accordance with the rules and procedures and within the established deadlines (Brussels time) of that system. If the transaction meets its settlement requirements, Euroclear or Clearstream Luxembourg, as the case may be, will deliver instructions to its respective depositary to take action to effect final settlement on its behalf by delivering or receiving interests in the relevant global notes in DTC, and making or receiving payment in accordance with normal procedures for same-day funds settlement applicable to DTC. Euroclear Participants and Clearstream Luxembourg Participants may not deliver instructions directly to the depositaries for Euroclear or Clearstream Luxembourg.

Because of time zone differences, the securities account of a Euroclear Participant or Clearstream Luxembourg Participant that purchases an interest in a global note from a participant will be credited on the business day for Euroclear or Clearstream Luxembourg immediately following the DTC settlement date. Cash received in Euroclear or Clearstream Luxembourg from the sale of an interest in a global note to a DTC participant will be received with value on the DTC settlement date but will be available in the relevant Euroclear or Clearstream Luxembourg cash account as of the business day for Euroclear or Clearstream Luxembourg following the DTC settlement date.

Although we understand that DTC, Euroclear and Clearstream Luxembourg have agreed to the foregoing procedures to facilitate transfers of interests in the global notes among participants in DTC, Euroclear and Clearstream Luxembourg, they are under no obligation to perform or to continue to perform those procedures, and those procedures may be discontinued at any time. Neither we nor the trustee will have any responsibility for the performance by DTC, Euroclear or Clearstream Luxembourg or their respective participants or indirect participants of their respective obligations under the rules and procedures governing their operations.

41

REGISTRATION RIGHTS

The following summary describes the material terms and conditions of the Registration Rights Agreement. This description is qualified in its entirety by reference to the terms and conditions of the Registration Rights Agreement. We urge you to read the Registration Rights Agreement in its entirety because it, not the following summary, will define your rights as a holder of Notes under that agreement. A copy of the Registration Rights Agreement was filed with the SEC and may also be obtained upon request at the address set forth under “Where You Can Find More Information and Incorporation by Reference.”

In connection with the issuance of the Old Notes, we entered into the Registration Rights Agreement pursuant to which we agreed, for the benefit of the holders of Old Notes, to use our commercially reasonable efforts to (1) cause to be filed with the SEC an exchange offer registration statement on an appropriate registration form with respect to an offer to exchange the Old Notes for New Notes having substantially identical terms as the Old Notes and evidencing the same indebtedness as the Old Notes (except that the New Notes will be registered under the Securities Act, will not be subject to certain restrictions on transfer or contain provisions relating to additional interest, will bear different CUSIP numbers than the Old Notes, generally will not entitle their holders to registration rights and will be subject to terms relating to book-entry procedures and administrative terms relating to transfers that differ from those of the Old Notes, as discussed below) and (2) cause such registration statement to be declared effective under the Securities Act.

When the SEC declares the registration statement of which this prospectus forms a part effective, we will offer the New Notes in return for the Old Notes. The exchange offer will remain open for at least 20 business days after the date we send notice of such exchange offer to the holders of Old Notes. For each Old Note surrendered to us in such exchange offer, the holder will receive a New Note of equal principal amount. Interest on each New Note will accrue from the last interest payment date on which interest was paid on the Old Notes or, if no interest has been paid on the Old Notes, from February 16, 2021. Old Notes accepted for exchange will cease to accrue interest from and after the date of consummation of the exchange offer. Holders of Old Notes whose Old Notes are accepted for exchange will not receive any payment in respect of accrued interest on such Old Notes otherwise payable on any interest payment date the record date for which occurs on or after consummation of the exchange offer.

By executing, or otherwise becoming bound by, the letter of transmittal, each tendering holder of Old Notes will generally represent that:

Under current SEC interpretations contained in several no-action letters to third parties, the New Notes will generally be freely transferable after the exchange offer without further registration under the Securities Act, except that any broker-dealer that participates in the exchange must deliver a prospectus meeting the requirements of the Securities Act when it resells the New Notes. See “The Exchange Offer—Resale of the New Notes.” Old Notes not tendered in the exchange offer will continue to be subject to all the terms and conditions

42

specified in the indenture, including transfer restrictions, but will generally not retain any rights under the Registration Rights Agreement (including with respect to additional interest) after the consummation of the exchange offer.

If we determine that a registered exchange offer is not available or may not be completed because it would violate any applicable law or applicable interpretations of the staff of the SEC, or, if for any reason, a registered exchange offer is not completed within 365 days after February 16, 2021, or any holder shall so request following the consummation of a registered exchange offer with respect to any Old Notes held by it that were not eligible for exchange, we will use our commercially reasonable efforts to cause to become effective a shelf registration statement relating to resales of the Old Notes, and to keep that shelf registration statement effective until the earliest of (A) the time when any such Old Notes covered by the shelf registration statement can be sold pursuant to Rule 144 without any limitations by non-affiliates of ours under clause (d) of Rule 144, (B) the date on which all such Old Notes are disposed of in accordance with the shelf registration statement and (C) one year after the original effective date of the shelf registration statement. We will, in the event of such a shelf registration, provide to each holder of Old Notes copies of a prospectus, notify each holder of Old Notes when the shelf registration statement has become effective and take certain other actions to permit resales of the Old Notes. A holder that sells Old Notes under the shelf registration statement generally will be required to make certain representations to us (as described in the Registration Rights Agreement), to be named as a selling security holder in the related prospectus and to deliver a prospectus to purchasers, will be subject to certain of the civil liability provisions under the Securities Act in connection with those sales and will be bound by the provisions of the Registration Rights Agreement that are applicable to such a holder (including certain indemnification obligations). Holders of Old Notes will also be required to suspend their use of the prospectus included in the shelf registration statement under specified circumstances upon receipt of notice from us.

A “registration default” will occur if for any reason a registered exchange offer is not completed within 365 days after February 16, 2021 (or, if required, the applicable shelf registration statement is not declared effective by the SEC on or before the date that is 545 days after February 16, 2021 (or, in some cases, 180 days after the receipt of a request for a shelf registration statement), or if any registration statement required by the Registration Rights Agreement has been declared effective and thereafter either ceases to be effective or the related prospectus ceases to be usable at any time during the required effectiveness period (subject to certain exceptions), and such failure to remain effective or be usable exists for more than 90 days (whether or not consecutive) in any 12-month period. In that case, the annual interest rate borne by the relevant Old Notes will be increased by 0.25% per annum until the exchange offer is completed, the shelf registration statement is declared effective or such registration statement and related prospectus become effective or usable again (or, if earlier, when our obligation to maintain the shelf registration statement ends). Any additional interest due will be payable on the same interest payment dates as interest on the Old Notes is payable.

This summary of the provisions of the Registration Rights Agreement does not purport to be complete and is subject to, and is qualified in its entirety by reference to, all the provisions of the Registration Rights Agreement, copies of which are available from us upon request.

43

PLAN OF DISTRIBUTION

Each broker-dealer that receives New Notes for its own account pursuant to the exchange offer must acknowledge that it will deliver a prospectus in connection with any resale of such New Notes. This prospectus, as it may be amended or supplemented from time to time, may be used by a broker-dealer in connection with the resale of New Notes received in exchange for Old Notes, where such Old Notes were acquired as a result of market-making activities or other trading activities. We have agreed that the registration statement will remain effective for a period ending on the earlier of (i) 90 days from the date on which the registration statement is declared effective and (ii) the date on which no participating broker-dealer is required to deliver a prospectus in connection with resales of New Notes issued in exchange for the Old Notes it acquired for its own account as a result of market-making or other trading activities.

We will not receive any proceeds from any sale of New Notes by broker-dealers. New Notes received by broker-dealers for their own account pursuant to the exchange offer may be sold from time to time, in one or more transactions, through the over-the-counter market, in negotiated transactions, through the writing of options on the New Notes or a combination of such methods of resale, at prevailing market prices at the time of resale, at prices related to such prevailing market prices or at negotiated prices. Any such resale may be made directly to purchasers or, alternatively, to or through brokers or dealers who may receive compensation in the form of commissions or concessions from any such broker-dealer or the purchasers of any such New Notes. Any broker-dealer that resells New Notes that were received by it for its own account pursuant to the exchange offer and any broker or dealer that participates in a distribution of such New Notes may be deemed to be an “underwriter” within the meaning of the Securities Act, and any profit on any such resale of New Notes and any commission or concessions received by any such persons may be deemed to be underwriting compensation under the Securities Act. The letter of transmittal states that, by acknowledging that it will deliver and by delivering a prospectus, a broker-dealer will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act. No broker-dealer participating in a distribution (within the meaning of the Securities Act) of the New Notes may use this prospectus.

For a period ending on the earlier of (i) 90 days from the date on which the registration statement is declared effective and (ii) the date on which no participating broker-dealer is required to deliver a prospectus in connection with resales of New Notes issued in exchange for the Old Notes it acquired for its own account as a result of market-making or other trading activities, we will promptly send additional copies of this prospectus and any amendment or supplement to this prospectus to any broker-dealer that requests such documents in the letter of transmittal. We have agreed to pay all expenses incident to the exchange offer (other than the expenses of counsel for the holders of the Old Notes), other than brokerage commissions and applicable transfer taxes, and will indemnify certain holders of the New Notes (including any broker-dealers) against certain liabilities, including liabilities under the Securities Act.

Based on interpretations by the staff of the SEC as set forth in no-action letters issued to third parties (including Exxon Capital Holdings Corporation (available May 13, 1988), Morgan Stanley & Co. Incorporated (available June 5, 1991), K-III Communications Corporation (available May 14, 1993) and Shearman & Sterling (available July 2, 1993)), we believe that the New Notes issued pursuant to the exchange offer may be offered for resale, resold and otherwise transferred by any holder of such New Notes, other than any such holder that is a broker-dealer or an affiliate of ours, without compliance with the registration and prospectus delivery provisions of the Securities Act, provided that:

We have not sought and do not intend to seek a no-action letter from the SEC with respect to the effects of the exchange offer, and there can be no assurance that the staff would make a similar determination with respect to the New Notes as it has in such no-action letters.

44

CERTAIN U.S. FEDERAL INCOME TAX CONSIDERATIONS

The following is a summary of certain U.S. federal income tax considerations of the exchange offer to holders of Old Notes and the ownership and disposition of the New Notes acquired in the exchange offer, but it does not purport to be a complete analysis of all the potential tax considerations relating to the exchange offer. This summary is based upon the provisions of the Internal Revenue Code of 1986, as amended (the “Code”), applicable U.S. Treasury Regulations promulgated thereunder, administrative rulings and judicial decisions, all as of the date of this prospectus. These authorities may be changed or subject to differing interpretations, possibly with retroactive effect, which may result in tax consequences different from those discussed below. We have not obtained, nor do we intend to obtain, a ruling from the IRS with respect to the statements made in this summary, and there can be no assurance that the IRS will agree with such statements or that a court would not sustain a challenge by the IRS.

This discussion assumes that the Old Notes and New Notes are held as “capital assets” within the meaning of Section 1221 of the Code (generally, property held for investment). This summary does not represent a detailed description of the U.S. federal income tax consequences to a holder of Old Notes or New Notes in light of such holder’s particular circumstances and does not address the alternative minimum tax, Medicare tax on net investment income, U.S. federal estate or gift tax or the effects of any state, local or non-U.S. tax laws. It is not intended to be, and should not be construed to be, legal or tax advice to any particular holder of Old Notes or acquirer of New Notes in the exchange offer.

This summary does not address all tax considerations that may be relevant to a holder of Old Notes or New Notes that is subject to special tax treatment under the U.S. federal income tax laws, including, without limitation:

If an entity or arrangement treated as a partnership or other pass-through entity for U.S. federal income tax purposes holds Old Notes or New Notes, the U.S. federal income tax treatment of a partner or other beneficial

45

owner in such partnership or other pass-through entity generally will depend upon the status of the partner or other beneficial owner and the activities of the partnership or other pass-through entity. If you are a partnership or other pass-through entity holding Old Notes or New Notes or a partner or other beneficial owner in such a partnership or other pass-through entity, you are urged to consult your own tax advisor about the U.S. federal income tax considerations with respect to the Exchange Offer.

EACH HOLDER SHOULD CONSULT ITS OWN TAX ADVISOR CONCERNING THE TAX CONSEQUENCES OF THE EXCHANGE OFFER AND OF OWNING THE NEW NOTES IN LIGHT OF EACH HOLDER’S PARTICULAR CIRCUMSTANCES UNDER U.S. FEDERAL TAX LAWS AND THE LAWS OF ANY STATE, LOCAL OR FOREIGN JURISDICTION.

Exchange Offer

The exchange of Old Notes for New Notes will not constitute a taxable exchange. As a result, (1) a holder of Old Notes should not recognize a taxable gain or loss as a result of exchanging such holder’s Old Notes for New Notes, (2) the holding period of the New Notes received should include the holding period of the Old Notes exchanged therefor, and (3) the adjusted tax basis of the New Notes received should be the same as the adjusted tax basis of the Old Notes exchanged therefor immediately before such exchange. The U.S. federal income tax consequences of holding and disposing of your New Notes generally will be the same as those applicable to your Old Notes.

46

PART II

INFORMATION NOT REQUIRED IN THE PROSPECTUS

Article X of our certificate of incorporation provides for the elimination, to the maximum extent permitted by the General Corporation Law of the State of Delaware, as the same exists or may be hereafter amended (the “DGCL”), of personal monetary liabilities of our directors for any breach of their fiduciary duties. Section 102(b)(7) of the DGCL enables a corporation in its certificate of incorporation to eliminate or limit the personal liability of members of its board of directors to the corporation or its stockholders for monetary damages for breach of fiduciary duty as a director, provided that the corporation shall not eliminate or limit the liability of a director for: (i) breaching his or her duty of loyalty; (ii) failing to act in good faith, engaging in intentional misconduct or knowingly violating the law; (iii) paying an unlawful dividend or approving an illegal stock repurchase; or (iv) obtaining an improper personal benefit.

Section 145 of the DGCL provides that a Delaware corporation may indemnify any persons who were, are or are threatened to be made, parties to any threatened, pending or completed action, suit or proceeding, whether civil, criminal, administrative or investigative (other than an action by or in the right of such corporation), by reason of the fact that such person is or was an officer, director, employee or agent of such corporation, or is or was serving at the request of such corporation as a director, officer, employee or agent of another corporation or enterprise. The indemnity may include expenses (including attorneys’ fees), judgments, fines and amounts paid in settlement actually and reasonably incurred by such person in connection with such action, suit or proceeding, provided such person acted in good faith and in a manner he reasonably believed to be in or not opposed to the corporation’s best interests and, with respect to any criminal action or proceeding, had no reasonable cause to believe that his conduct was illegal. Indemnification provided pursuant to Section 145 is not exclusive of any other rights to which those seeking indemnification may be entitled to under any bylaw, agreement, disinterested director vote, stockholder vote or otherwise. In addition, the statutes of Delaware contain provisions to the general effect that any director shall in the performance of his duties be fully protected in relying in good faith upon the books of account or records of the corporation or statements prepared by any official of the corporation. Our certificate of incorporation and bylaws provide that we shall indemnify our directors and officers and may indemnify our employees and other agents to the fullest extent permitted by the law.

Our bylaws provide that we shall provide, to the fullest extent authorized by the DGCL, indemnification against all expense, liability and loss reasonably incurred or suffered by our directors, officers or any other person who is or was serving at our request as a director, officer, employee, fiduciary, representative, partner or agent of another related entity and shall advance expenses to such persons, in respect of any action, suit or proceeding, whether civil, criminal, administrative or investigative, by reason of the fact that he or she is or was serving in such capacity. In addition, we maintain directors’ and officers’ liability insurance which insures against certain liabilities that our directors or officers may incur in such capacities.

We also have in place agreements with certain of our officers and directors which affirm our obligation to indemnify them to the fullest extent permitted by law and contain various procedural and other provisions which expand the protection afforded by our bylaws.

II-1

(a) Exhibits

The undersigned registrant hereby undertakes:

(1) To file, during any period in which offers or sales are being made, a post-effective amendment to this registration statement:

(i) To include any prospectus required by Section 10(a)(3) of the Securities Act;

II-2

(ii) To reflect in the prospectus any facts or events arising after the effective date of the registration statement (or the most recent post-effective amendment thereof) which, individually or in the aggregate, represent a fundamental change in the information set forth in the registration statement. Notwithstanding the foregoing, any increase or decrease in volume of securities offered (if the total dollar value of securities offered would not exceed that which was registered) and any deviation from the low or high end of the estimated maximum offering range may be reflected in the form of prospectus filed with the SEC pursuant to Rule 424(b) under the Securities Act if, in the aggregate, the changes in volume and price represent no more than a 20% change in the maximum aggregate offering price set forth in the “Calculation of Registration Fee” table in the effective registration statement; and

(iii) To include any material information with respect to the plan of distribution not previously disclosed in the registration statement or any material change to such information in the registration statement.

(2) That, for purposes of determining any liability under the Securities Act, each such post-effective amendment shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(3) To remove from registration by means of a post-effective amendment any of the securities being registered which remain unsold at the termination of the offering.

(4) That, for the purpose of determining liability under the Securities Act to any purchaser, each prospectus filed pursuant to Rule 424(b) under the Securities Act as part of a registration statement relating to an offering, other than registration statements relying on Rule 430B under the Securities Act or other than prospectuses filed in reliance on Rule 430A under the Securities Act, shall be deemed to be part of and included in the registration statement as of the date it is first used after effectiveness; provided, however, that no statement made in a registration statement or prospectus that is part of the registration statement or made in a document incorporated or deemed incorporated by reference into the registration statement or prospectus that is part of the registration statement will, as to a purchaser with a time of contract of sale prior to such first use, supersede or modify any statement that was made in the registration statement or prospectus that was part of the registration statement or made in any such document immediately prior to such date of first use.

(5) That, for the purpose of determining liability of the registrant under the Securities Act to any purchaser in the initial distribution of the securities: the undersigned registrant undertakes that, in a primary offering of securities of the undersigned registrant pursuant to this registration statement, regardless of the underwriting method used to sell the securities to the purchaser, if the securities are offered or sold to such purchaser by means of any of the following communications, the undersigned registrant will be a seller to the purchaser and will be considered to offer or sell such securities to such purchaser:

(i) Any preliminary prospectus or prospectus of the undersigned registrant relating to the offering required to be filed pursuant to Rule 424 under the Securities Act;

(ii) Any free writing prospectus relating to the offering prepared by or on behalf of the undersigned registrant or used or referred to by the undersigned registrant;

of an employee benefit plan’s annual report pursuant to Section 15(d) of the Exchange Act) that is incorporated by reference in the registration statement shall be deemed to be a new registration statement relating to the securities offered therein, and the offering of such securities at that time shall be deemed to be the initial bona fide offering thereof.

(7) Insofar as indemnification for liabilities arising under the Securities Act may be permitted to directors, officers and controlling persons of the registrant pursuant to the foregoing provisions, or otherwise, the registrant has been advised that in the opinion of the SEC such indemnification is against public policy as expressed in the Securities Act and is, therefore, unenforceable. In the event that a claim for indemnification against such liabilities (other than the payment by the registrant of expenses incurred or paid by a director, officer or controlling person of the registrant in the successful defense of any action, suit or proceeding) is asserted by such director, officer or controlling person in connection with the securities being registered, the registrant will, unless in the opinion of their counsel the matter has been settled by controlling precedent, submit to a court of appropriate jurisdiction the question whether such indemnification by them is against public policy as expressed in the Securities Act and will be governed by the final adjudication of such issue.

(8) The undersigned registrant hereby undertakes to respond to requests for information that is incorporated by reference into the prospectus pursuant to Items 4, 10(b), 11 or 13 of this Form, within one business day of receipt of such request, and to send the incorporated documents by first-class mail or other equally prompt means. This includes information contained in documents filed subsequent to the effective date of the registration statement through the date of responding to the request.

(9) The undersigned registrant hereby undertakes to supply by means of a post-effective amendment all information concerning a transaction, and the company being acquired involved therein, that was not the subject of and included in the registration statement when it became effective.

The New Notes are to be issued pursuant to the Indenture dated as of September 15, 2015 (the “Base Indenture”) between the Company and U.S. Bank Trust Company, National Association (formerly U.S. Bank National Association), as trustee (the “Trustee”), as amended and supplemented by the Third Supplemental Indenture dated as of February 16, 2021 (together with the Base Indenture, the “Indenture”) between the Company and the Trustee, as trustee.

In connection with this opinion, we have examined originals or copies, certified or otherwise identified to our satisfaction, of (i) the amended and restated certificate of incorporation of the Company, as amended to the date hereof and on file with the Secretary of State of the State of Delaware, (ii) the amended and restated by-laws of the Company, as amended to the date hereof, (iii) the Registration Statement, including the documents and information incorporated by reference therein, (iv) the Indenture, (v) the form of New Notes, (vi) the Form T-1 of the Trustee filed with the Commission with respect to the transaction, (vii) such records of the corporate proceedings of the Company as we have deemed material, and (viii) such other certificates, receipts, records and documents as we have deemed necessary or appropriate for purposes of this opinion.

Exhibit 1

ARTICLES OF ASSOCIATION

OF

U. S. BANK TRUST COMPANY, NATIONAL ASSOCIATION

For the purpose of organizing an association (the “Association”) to perform any lawful activities of national banks, the undersigned enter into the following Articles of Association:

FIRST. The title of this Association shall be U. S. Bank Trust Company, National Association.

SECOND. The main office of the Association shall be in the city of Portland, county of Multnomah, state of Oregon. The business of the Association will be limited to fiduciary powers and the support of activities incidental to the exercise of those powers. The Association may not expand or alter its business beyond that stated in this article without the prior approval of the Comptroller of the Currency.

THIRD. The board of directors of the Association shall consist of not less than five nor more than twenty-five persons, the exact number to be fixed and determined from time to time by resolution of a majority of the full board of directors or by resolution of a majority of the shareholders at any annual or special meeting thereof. Each director shall own common or preferred stock of the Association or of a holding company owning the Association, with an aggregate par, fair market, or equity value of not less than $1,000, as of either (i) the date of purchase, (ii) the date the person became a director, or (iii) the date of that person’s most recent election to the board of directors, whichever is more recent. Any combination of common or preferred stock of the Association or holding company may be used.

Any vacancy in the board of directors may be filled by action of a majority of the remaining directors between meetings of shareholders. The board of directors may increase the number of directors up to the maximum pennitted by law. Terms of directors, including directors selected to fill vacancies, shall expire at the next regular meeting of shareholders at which directors are elected, unless the directors resign or are removed from office. Despite the expiration of a director’s term, the director shall continue to serve until his or her successor is elected and qualified or until there is a decrease in the number of directors and his or her position is eliminated.

Honorary or advisory members of the board of directors, without voting power or power of final decision in matters concerning the business of the Association, may be appointed by resolution of a majority of the full board of directors, or by resolution of shareholders at any annual or special meeting. Honorary or advisory directors shall not be counted to determined the number of directors of the Association or the presence of a quorum in connection with any board action, and shall not be required to own qualifying shares.

FOURTH. There shall be an annual meeting of the shareholders to elect directors and transact whatever other business may be brought before the meeting. It shall be held at the main office or any other convenient place the board of directors may designate, on the day of each year specified therefor in the Bylaws, or if that day falls on a legal holiday in the state in which the

- 1 -

Association is located, on the next following banking day. If no election is held on the day fixed or in the event of a legal holiday on the following banking day, an election may be held on any subsequent day within 60 days of the day fixed, to be designated by the board of directors, or, if the directors fail to fix the day, by shareholders representing two-thirds of the shares issued and outstanding. In all cases, at least 10 days’ advance notice of the meeting shall be given to the shareholders by first-class mail.

In all elections of directors, the number of votes each common shareholder may cast will be determined by multiplying the number of shares he or she owns by the number of directors to be elected. Those votes may be cumulated and cast for a single candidate or may be distributed among two or more candidates in the manner selected by the shareholder. On all other questions, each common shareholder shall be entitled to one vote for each share of stock held by him or her.

A director may resign at any time by delivering written notice to the board of directors, its chairperson, or to the Association, which resignation shall be effective when the notice is delivered unless the notice specifies a later effective date.

A director may be removed by the shareholders at a meeting called to remove him or her, when notice of the meeting stating that the purpose or one of the purposes is to remove him or her is provided, if there is a failure to fulfill one of the affirmative requirements for qualification, or for cause; provided, however, that a director may not be removed if the number of votes sufficient to elect him or her under cumulative voting is voted against his or her removal.

FIFTH. The authorized amount of capital stock of the Association shall be 1,000,000 shares of common stock of the par value of ten dollars ($10) each; but said capital stock may be increased or decreased from time to time, according to the provisions of the laws of the United States. The Association shall have only one class of capital stock.

No holder of shares of the capital stock of any class of the Association shall have any preemptive or preferential right of subscription to any shares of any class of stock of the Association, whether now or hereafter authorized, or to any obligations convertible into stock of the Association, issued, or sold, nor any right of subscription to any thereof other than such, if any, as the board of directors, in its discretion, may from time to time determine and at such price as the board of directors may from time to time fix.

Transfers of the Association’s stock are subject to the prior written approval of a federal depository institution regulatory agency. If no other agency approval is required, the approval of the Comptroller of the Currency must be obtained prior to any such transfers.

Unless otherwise specified in the Articles of Association or required by law, (1) all matters requiring shareholder action, including amendments to the Articles of Association must be approved by shareholders owning a majority voting interest in the outstanding voting stock, and (2) each shareholder shall be entitled to one vote per share.

- 2 -

Unless otherwise specified in the Articles of Association or required by law, all shares of voting stock shall be voted together as a class, on any matters requiring shareholder approval.

Unless otherwise provided in the Bylaws, the record date for determining shareholders entitled to notice of and to vote at any meeting is the close of business on the day before the first notice is mailed or otherwise sent to the shareholders, provided that in no event may a record date be more than 70 days before the meeting.

The Association, at any time and from time to time, may authorize and issue debt obligations, whether or not subordinated, without the approval of the shareholders. Obligations classified as debt, whether or not subordinated, which may be issued by the Association without the approval of shareholders, do not carry voting rights on any issue, including an increase or decrease in the aggregate number of the securities, or the exchange or reclassification of all or part of securities into securities of another class or series.

SIXTH. The board of directors shall appoint one of its members president of this Association and one of its members chairperson of the board and shall have the power to appoint one or more vice presidents, a secretary who shall keep minutes of the directors’ and shareholders’ meetings and be responsible for authenticating the records of the Association, and such other officers and employees as may be required to transact the business of this Association. A duly appointed officer may appoint one or more officers or assistant officers if authorized by the board of directors in accordance with the Bylaws.

The board of directors shall have the power to:

- 3 -

SEVENTH. The board of directors shall have the power to change the location of the main office to any authorized branch within the limits of the city of Portland, Oregon, without the approval of the shareholders, or with a vote of shareholders owning two-thirds of the stock of the Association for a location outside such limits and upon receipt of a certificate of approval from the Comptroller of the Currency, to any other location within or outside the limits of the city of Portland, Oregon, but not more than thirty miles beyond such limits. The board of directors shall have the power to establish or change the location of any office or offices of the Association to any other location permitted under applicable law, without approval of shareholders, subject to approval by the Comptroller of the Currency.

EIGHTH. The corporate existence of this Association shall continue until termination according to the laws of the United States.

NINTH. The board of directors of the Association, or any shareholder owning, in the aggregate, not less than 25 percent of the stock of the Association, may call a special meeting of shareholders at any time. Unless otherwise provided by the Bylaws or the laws of the United States, or waived by shareholders, a notice of the time, place, and purpose of every annual and special meeting of the shareholders shall be given by first-class mail, postage prepaid, mailed at least 10, and no more than 60, days prior to the date of the meeting to each shareholder of record at his/her address as shown upon the books of the Association. Unless otherwise provided by the Bylaws, any action requiring approval of shareholders must be effected at a duly called annual or special meeting.

TENTH. These Articles of Association may be amended at any regular or special meeting of the shareholders by the affirmative vote of the holders of a majority of the stock of the Association, unless the vote of the holders of a greater amount of stock is required by law, and in that case by the vote of the holders of such greater amount; provided, that the scope of the Association’s activities and services may not be expanded without the prior written approval of the Comptroller of the Currency. The Association’s board of directors may propose one or more amendments to the Articles of Association for submission to the shareholders.

DESCRIPTION OF OLD NOTES (See Instruction 2.) List below the Old Notes (as defined below) to which this Letter of Transmittal relates.

1

The undersigned acknowledges that he, she or it has received the prospectus, dated             , 2022 (as the same may be amended, supplemented or modified from time to time, the “Prospectus”), of Biogen Inc., a Delaware corporation (the “Issuer”) and this Letter of Transmittal, or a facsimile thereof (the “Letter of Transmittal”), which together constitute the Issuer’s offer (the “Exchange Offer”) to exchange up to $700,731,000 aggregate principal amount of its 3.250% Senior Notes due 2051 (the “Old Notes”) for a like principal amount of its 3.250% Senior Notes due 2051 (the “New Notes”), which have been registered under the Securities Act of 1933, as amended (the “Securities Act”), from the registered holders thereof (each, a “Holder” and, collectively, the “Holders”), upon the terms and subject to the conditions of the Exchange Offer, as set forth in the Prospectus and this Letter of Transmittal.

In the event of any conflict between the Prospectus and the Letter of Transmittal, the Prospectus shall govern. Terms used but not defined herein have the same meanings given to them in the Prospectus.

The terms of the New Notes are substantially identical to the terms of the Old Notes, except that the offer and exchange of the New Notes will be registered under the Securities Act, and the New Notes generally have no transfer restrictions, rights to additional interest or registration rights.

For each Old Note accepted for exchange, the Holder of such Old Note will receive a New Note having a principal amount equal to that of the surrendered Old Note. Interest on the New Notes will accrue from the last date on which interest was paid on the Old Notes. Accordingly, registered holders of New Notes on the record date for the first interest payment date following the consummation of the Exchange Offer will receive interest accruing from the last interest payment date on which interest was paid on the Old Notes. Old Notes accepted for exchange will cease to accrue interest from and after the date of consummation of the Exchange Offer. Holders of Old Notes whose Old Notes are accepted for exchange will not receive any payment in respect of accrued interest on such Old Notes otherwise payable on any interest payment date the record date for which occurs on or after consummation of the Exchange Offer.

This Letter of Transmittal must be completed and submitted by a tendering Holder if (i) Old Notes are tendered to the account maintained by the Exchange Agent at The Depository Trust Company (“DTC”) in accordance with the book-entry procedures set forth in the Prospectus under “The Exchange Offer—Book-Entry Transfer” and (ii) an Agent’s Message (as defined below) is not delivered. See Instruction 1. DELIVERY OF DOCUMENTS TO DTC DOES NOT CONSTITUTE DELIVERY TO THE EXCHANGE AGENT.

2

BOOK-ENTRY TRANSFER

By crediting the Old Notes to the Exchange Agent’s account at the facilities of DTC and by complying with applicable DTC procedures with respect to the Exchange Offer, including transmitting to the Exchange Agent a computer-generated Agent’s Message in which the holder of the Old Notes acknowledges and agrees to be bound by the terms of, and makes the representations and warranties contained in, the Letter of Transmittal, the participant in DTC confirms on behalf of itself and the beneficial owners of such Old Notes all provisions of this Letter of Transmittal (including all representations and warranties) applicable to it and such beneficial owner as fully as if it had completed the information required herein and executed and transmitted this Letter of Transmittal to the Exchange Agent.

NOTE: SIGNATURES MUST BE PROVIDED BELOW. PLEASE READ THE ACCOMPANYING

INSTRUCTIONS CAREFULLY.

LADIES AND GENTLEMEN:

Upon the terms and subject to the conditions of the Exchange Offer, the undersigned hereby tenders to the Issuer the aggregate principal amount of Old Notes described above. Subject to, and effective upon, the acceptance for exchange of the Old Notes tendered hereby, the undersigned hereby sells, assigns and transfers to, or upon the order of, the Issuer all right, title and interest in and to such Old Notes as are being tendered hereby.

The undersigned hereby irrevocably constitutes and appoints the Exchange Agent as the undersigned’s true and lawful agent, attorney-in-fact and proxy with respect to the Old Notes tendered hereby, with full power of substitution (such power of attorney being deemed to be an irrevocable power coupled with an interest), among other things, to cause the Old Notes to be assigned, transferred and exchanged.

The undersigned hereby represents and warrants that (a) the undersigned has full power and authority to tender, sell, assign and transfer the Old Notes and (b) when the Old Notes are accepted for exchange, the Issuer will acquire good and unencumbered title to such Old Notes, free and clear of all liens, restrictions, charges and encumbrances and not subject to any adverse claim, and such Old Notes will not have been transferred to the Issuer in violation of any contractual or other restriction on the transfer thereof.

The undersigned, either as or on behalf of the beneficial holder of the Old Notes tendered hereby, acknowledges that the Exchange Offer is being made in reliance on existing interpretations of the staff of the U.S. Securities and Exchange Commission (the “SEC”) contained in several no-action letters to third parties to the effect that new securities issued pursuant to a registered exchange offer (of the type contemplated by the Exchange Offer) in exchange for substantially identical outstanding securities would in general be freely transferable without further registration under the Securities Act by a holder thereof (other than a broker-dealer or an “affiliate” (within the meaning of Rule 405 of the Securities Act) of the Issuer), if such holder (a) is acquiring the new securities in the ordinary course of its business and (b) is not engaged in, and does not intend to engage in, a distribution (within the meaning of the Securities Act) of the new securities to be received in the registered exchange offer and has no arrangement or understanding with any person to participate in a distribution of the new securities. However, the Issuer has not sought, and does not intend to seek, a no-action letter from the SEC with respect to the effects of the Exchange Offer, and there can be no assurance that the SEC staff would make a similar determination with respect to the New Notes as it has made in previous no-action letters.

The undersigned, either as or on behalf of the beneficial holder of the Old Notes tendered hereby, represents, acknowledges and agrees that: (a) if such holder is not a broker-dealer or an “affiliate” of the Issuer, it is (i) acquiring New Notes in the ordinary course of its business and (ii) not engaged in, and does not intend to engage in, a distribution (within the meaning of the Securities Act) of the New Notes to be received in the Exchange Offer and has no arrangement or understanding with any person to participate in a distribution of the New Notes; (b) if such holder is a broker-dealer that will receive New Notes for its own account in exchange for Old Notes, the Old Notes to be exchanged for the New Notes (other than Old Notes acquired directly from the Issuer for its own account) were acquired by it as a result of market-making or other trading activities and that it will deliver (or, to the extent permitted by law, make available) a prospectus meeting the requirements of the Securities Act to purchasers in connection with any resale of such New Notes; however, by so acknowledging and by delivering a prospectus meeting the requirements of the Securities Act, the undersigned will not be deemed to admit that it is an “underwriter” within the meaning of the Securities Act; and (c) if such holder is (i) a broker-dealer that will receive New Notes in exchange for an unsold allotment from the original sale of the Old Notes, (ii) an affiliate of the Issuer or (iii) acquiring New Notes for the purpose of distributing them, it (A) cannot rely on the interpretations of the SEC staff expressed in the no-action letters described above and (B) must comply with the registration and prospectus delivery requirements of the Securities Act in order to resell such New Notes (or, in the case of an affiliate, any and all New Notes held by it) and be identified as an underwriter in the relevant prospectus. The undersigned is not acting on behalf of any person who could not truthfully make the foregoing representations and warranties.

The SEC has taken the position that broker-dealers may fulfill their prospectus delivery requirements with respect to the New Notes (other than a resale of New Notes received in exchange for an unsold allotment from the original sale of the Old Notes) with the Prospectus. The Prospectus, as it may be amended or supplemented from time to time, may be used by certain broker-dealers (as specified in the Registration Rights Agreement with respect to the Old Notes referenced in the Prospectus)

4

(“Participating Broker-Dealers”) for a period of time starting on the Expiration Date and ending on the earlier of (i) 90 days from the date on which the registration statement is declared effective and (ii) the date on which no Participating Broker-Dealer is required to deliver a prospectus in connection with resales of New Notes issued in exchange for the Old Notes it acquired for its own account as a result of market-making or other trading activities. The Issuer has agreed that, for such period of time, it will promptly send additional copies of the Prospectus and any amendment or supplement thereof to any Participating Broker-Dealer that requests such documents in the Letter of Transmittal. By tendering in the Exchange Offer, each broker-dealer that receives New Notes pursuant to the Exchange Offer acknowledges and agrees to notify the Issuer before using the Prospectus in connection with the sale or transfer of New Notes and agrees that, upon receipt of notice from the Issuer of the happening of any event during the period a Registration Statement is effective that makes any statement made in such Registration Statement or the Prospectus or any free writing prospectus with respect thereto untrue in any material respect or that requires the making of any changes in such Registration Statement or Prospectus or any such free writing prospectus in order to make the statements therein not misleading, such broker-dealer will suspend use of the Prospectus until (i) the Issuer has amended or supplemented the Prospectus to correct such misstatement or omission and such broker-dealer has obtained a copy of such amended or supplemented Prospectus or (ii) such broker-dealer is advised in writing by the Issuer that the use of the Prospectus may be resumed, and has received copies of any additional or supplemental filings that are incorporated by reference in the Prospectus. Except as described above, the Prospectus may not be used for or in connection with an offer to resell, a resale or any other retransfer of New Notes. No broker-dealer participating in a distribution (within the meaning of the Securities Act) of the New Notes may use the Prospectus.

The undersigned will, upon request, execute and deliver any additional documents deemed by the Issuer to be necessary or desirable to complete the sale, assignment and transfer of the Old Notes tendered hereby.

All authority conferred or agreed to be conferred in this Letter of Transmittal and every obligation of the undersigned hereunder shall be binding upon the successors, assigns, heirs, executors, administrators, trustees in bankruptcy and legal representatives of the undersigned and shall not be affected by, and shall survive, the death or incapacity of the undersigned.

Tenders of Old Notes may be withdrawn at any time before the Expiration Date, but tenders that are not withdrawn are irrevocable. See information described in the Prospectus under “The Exchange Offer—Withdrawal Rights.”

The undersigned understands that a tender of Old Notes pursuant to any of the procedures described in the “The Exchange Offer—Procedures for Tendering Old Notes” section of the Prospectus and in the instructions hereto will constitute a binding agreement between the undersigned and the Issuer upon the terms and subject to the conditions set forth in the Prospectus and this Letter of Transmittal, including the undersigned’s representation that the undersigned owns the Old Notes being tendered. The undersigned recognizes that, under certain circumstances set forth in the Prospectus, the Issuer may not be required to accept for exchange any of the Old Notes tendered hereby.

Unless otherwise indicated herein in the box entitled “Special Issuance Instructions” below, the New Notes will be credited to the account indicated above maintained at DTC.

THE UNDERSIGNED, BY COMPLETING THE BOX ENTITLED “DESCRIPTION OF OLD NOTES” ABOVE AND SIGNING THIS LETTER OF TRANSMITTAL, WILL BE DEEMED TO HAVE TENDERED THE OLD NOTES AS SET FORTH IN SUCH BOX ABOVE.

A Book-Entry Confirmation for such Old Notes, as well as a properly completed and duly executed Letter of Transmittal, or a facsimile copy thereof, and all other documents required by this Letter of Transmittal, must be received by the Exchange Agent at the address set forth herein on or before the Expiration Date. Old Notes tendered hereby must be in minimum denominations of $2,000 in principal amount and integral multiples of $1,000 in excess thereof. Tenders by book-entry transfer may also be made by delivering an Agent’s Message in lieu of this Letter of Transmittal. “Agent’s Message” means a message transmitted by DTC to, and received by, the Exchange Agent and forming a part of a Book-Entry Confirmation, that states that DTC has received an express acknowledgment that such participant has received and agrees to be bound by the Letter of Transmittal, and that we may enforce the Letter of Transmittal against such participant. “Book-Entry Confirmation” means a timely confirmation of book-entry transfer of Old Notes into the Exchange Agent’s account at DTC using the procedure for book-entry transfer described in the Prospectus under “The Exchange Offer—Book-Entry Transfer.”

THE ISSUER WILL NOT ACCEPT ANY ALTERNATIVE, CONDITIONAL OR CONTINGENT TENDERS. EACH TENDERING HOLDER, BY EXECUTION OF A LETTER OF TRANSMITTAL (OR FACSIMILE THEREOF OR AGENT’S MESSAGE IN LIEU THEREOF), WAIVES ANY RIGHT TO RECEIVE ANY NOTICE OF THE ACCEPTANCE OF SUCH TENDER.

2. Inadequate Space. If the space provided in the box captioned “Description of Old Notes” above is inadequate, the principal amount of Notes and any other required information should be listed on a separate signed schedule and such schedule should be attached to this Letter of Transmittal.

3. Signatures on this Letter of Transmittal; Bond Powers and Endorsements. If this Letter of Transmittal is signed by the registered Holder(s) of the Notes tendered hereby, the signature(s) must correspond exactly with the name(s) so registered without any change whatsoever. If any of the Old Notes tendered hereby are owned of record by two or more joint owners, all such owners must sign this Letter of Transmittal. If any of the Old Notes are registered in different name(s), it will be necessary to complete, sign and submit as many separate Letters of Transmittal (or facsimiles thereof or Agent’s Messages in lieu thereof) as there are different registrations.

Signatures on this Letter of Transmittal must be guaranteed, unless the Old Notes being surrendered for exchange are tendered (i) by a registered Holder of the Old Notes who has not completed the box entitled “Special Issuance Instructions” on the Letter of Transmittal, or (ii) for the account of an “eligible guarantor” institution within the meaning of Rule 17Ad-15 under the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or a commercial bank or trust company having an office or correspondent in the United States that is a member in good standing of a medallion program recognized by the Securities Transfer Association Inc., including the Securities Transfer Agents Medallion Program, the Stock Exchanges Medallion Program and the New York Stock Exchange Medallion Signature Program (each, an “Eligible Institution”). If signatures on this Letter of Transmittal are required to be guaranteed, the guarantees must be by an Eligible Institution.

9

If this Letter of Transmittal is signed by a person or persons other than the registered holder or holders of Old Notes, the Old Notes must be endorsed or accompanied by appropriate powers of attorney, in either case signed exactly as the name or names of the registered holder or holders appear on the Old Notes and with the signatures guaranteed.

If this Letter of Transmittal or any Old Notes or powers of attorney are signed by trustees, executors, administrators, guardians, attorneys-in-fact, officers of corporations or others acting in a fiduciary or representative capacity, the person should so indicate when signing and, unless waived by us, proper evidence satisfactory to us of such person’s authority to so act must be submitted.

4. Special Issuance Instructions. Tendering Holders of Old Notes should indicate in the applicable box the name and address to which New Notes issued pursuant to the Exchange Offer are to be issued, if different from the name or address of the person(s) signing this Letter of Transmittal. In the case of issuance in a different name, the employer identification or social security number(s) of the person(s) named must also be indicated. Holders tendering Old Notes may request that Old Notes not exchanged be credited to such account maintained at DTC as such Holder may designate herein. If no such instructions are given, such Old Notes not exchanged will be returned to the name and address of the person(s) signing this Letter of Transmittal.

5. Transfer Taxes. Except as otherwise provided in this Instruction 5, the Issuer will pay any transfer taxes with respect to the transfer of Old Notes to it or its order pursuant to the Exchange Offer. If, however, New Notes or substitute Old Notes not exchanged are to be delivered to or registered or issued in the name of, any person other than the registered Holder(s) of the Old Notes tendered hereby, or if tendered Old Notes are registered in the name of any person other than the person(s) signing this Letter of Transmittal, or if a transfer tax is imposed for any reason other than the transfer of Old Notes to the Issuer or its order pursuant to the Exchange Offer, the amount of any such transfer taxes (whether imposed on the registered Holder(s) or any other person) payable on account of the transfer to such person will be payable by the Holder(s) tendering hereby. If satisfactory evidence of payment of such taxes or exemption therefrom is not submitted herewith, the amount of such transfer taxes will be billed directly to such tendering Holder(s).

6. Waiver of Conditions. The Issuer reserves the absolute right to waive satisfaction of any or all conditions enumerated in the Prospectus.

7. Taxpayer Identification Number; Backup Withholding; IRS Form W-9. U.S. federal income tax laws generally require that a tendering Holder that is a U.S. person (including a resident alien) provides the Exchange Agent with such Holder’s correct Taxpayer Identification Number (“TIN”) on IRS Form W-9, Request for Taxpayer Identification Number and Certification, below (the “IRS Form W-9”), which in the case of a Holder who is an individual, is his or her social security number. If the tendering Holder is a non-resident alien or a foreign entity, other requirements (as described below) will apply. If the Exchange Agent is not provided with the correct TIN or an adequate basis for an exemption from backup withholding, such tendering Holder may be subject to a $50 penalty imposed by the Internal Revenue Service (the “IRS”). In addition, failure to provide the Exchange Agent with the correct TIN or an adequate basis for an exemption from backup withholding may result in backup withholding on payments made to the tendering Holder pursuant to the Exchange Offer at a current rate of 24%. If withholding results in an overpayment of taxes, the Holder may obtain a refund from the IRS.

Exempt Holders of the Notes (including, among others, all corporations) are not subject to these backup withholding and reporting requirements. See the Instructions for the Requester of Form W-9 (the “W-9 Guidelines”) for additional instructions, which may be obtained via the IRS website at www.irs.gov.

To prevent backup withholding, each tendering Holder that is a U.S. person (including a resident alien) must provide its correct TIN by completing the IRS Form W-9 set forth below, certifying, under penalties of perjury, that such Holder is a U.S. person (including a resident alien), that the TIN provided is correct (or that such Holder is awaiting a TIN) and that (i) such Holder is exempt from backup withholding, (ii) such Holder has not been notified by the IRS that such Holder is subject to backup withholding as a result of a failure to report all interest or dividends, or (iii) the IRS has notified such Holder that such Holder is no longer subject to backup withholding. If the Old Notes are in more than one name or are not in the name of the actual owner, such Holder should consult the W-9 Guidelines for information on which TIN to report. If such Holder does not have a TIN, such Holder should consult the W-9 Guidelines for instructions on applying for a TIN, write “Applied For” in the space reserved for the TIN, as shown on IRS Form W-9. Note: Writing “Applied For” on the IRS Form W-9 means that such Holder has already applied for a TIN or that such Holder intends to apply for one in the near future. If such Holder does not provide its TIN to the Exchange Agent within 60 days, backup withholding will begin and continue until such Holder furnishes its TIN to the Exchange Agent.

10

A tendering Holder that is a non-resident alien or a foreign entity must submit the appropriate completed IRS Form W-8 to avoid backup withholding.
