tender and do not validly withdraw Notes at or prior to the Expiration Date or (ii)&nbsp;deliver a valid notice of guaranteed delivery and all other required documents at or prior to the Expiration Date and tender their Notes at or prior to 5:00
p.m., New York City time, on the second business day after the Expiration Date, expected to be on February&nbsp;12, 2021, pursuant to certain guaranteed delivery procedures and subject in each case to the delivery of the certification of eligibility
and the tender being in the Authorized Denominations (as defined in the Offer to Purchase), and whose Notes are accepted for purchase by Biogen, will receive consideration in the Cash Offer equal to the Tender Consideration (as defined below). </P>
<P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The Tender Consideration will be calculated at 11:00 a.m., New York City time, on February&nbsp;10, 2021, unless extended (such date and time, as it may be
extended, the &#147;Pricing Time&#148;). The &#147;Tender Consideration&#148; for the Notes, which will be determined in accordance with standard market practice as described in the Offer to Purchase, equates to a yield to the par call date of the
Notes equal to the Fixed Spread specified for the Notes in the table above over the reference yield, which will be based on the <FONT STYLE="white-space:nowrap">bid-side</FONT> yield of the Reference U.S. Treasury Security specified for the Notes in
the table above at the Pricing Time. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">In addition to the Tender Consideration, Biogen also intends to pay in cash accrued and unpaid interest on the Notes
accepted for purchase from the last interest payment date to, but excluding, the Settlement Date (the &#147;Accrued Coupon Payment&#148;). Interest will cease to accrue on the Settlement Date for all Notes accepted in the Cash Offer, including those
tendered pursuant to the guaranteed delivery procedures. The last interest payment date for the Notes is expected to be September&nbsp;15, 2020. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">The
complete terms and conditions of the Cash Offer are set forth in the Cash Offer Documents, which will be distributed to Eligible Holders in connection with the proposed Cash Offer. The Cash Offer is subject to certain conditions, including
(i)&nbsp;the Aggregate Maximum Cash Offer Condition, (ii)&nbsp;the timely satisfaction or waiver of all of the conditions precedent to the completion of the Exchange Offer (the &#147;Exchange Offer Completion Condition&#148;), and (iii)&nbsp;certain
customary conditions, as described in the Offer to Purchase. </P> <P STYLE="margin-top:12pt; margin-bottom:0pt; font-size:10pt; font-family:Times New Roman">Biogen will terminate the Cash Offer if it terminates the Exchange Offer, and Biogen will
terminate the Exchange Offer if it terminates the Cash Offer. Biogen may not waive the Exchange Offer Completion Condition; however, subject to applicable law, Biogen reserves the right, in its reasonable discretion, to waive any of the other
conditions, including the Aggregate Maximum Cash Offer Condition. Biogen may terminate the Cash Offer if the Aggregate Maximum Cash Offer Condition is not satisfied or waived, in which case it will also terminate the Exchange Offer. </P>
