B RSNs shall not be subject to optional redemption at any time. (5) Contract adjustment payments may be deferred as described under “Description of the Purchase Contracts—Remarketing.” The diagram above describes each of a Corporate Unit, a Treasury Unit and separate RSNs. • Because both series of RSNs are issued in minimum denominations of $1,000, holders of Corporate Units may only create Treasury Units in integral multiples of 40 Corporate Units. • To create 40 Treasury Units, a holder separates 40 Corporate Units into their three components—40 purchase contracts, a Series 2025B RSN having a principal amount of $1,000 and a Series 2025C RSN having a principal amount of $1,000—

and then combines the purchase contracts with two Treasury securities that mature on or prior to December 15, 2028, each having a principal amount at maturity of $1,000. • The RSN of each series, which is no longer a component of Corporate Units, is released from the pledge under the purchase contract and pledge agreement and delivered to the holder and is tradable as a separate security. • A holder owns the two Treasury securities that form a part of the 40 Treasury Units but will pledge them to the Company through the collateral agent to secure the holder’s obligation under the related purchase contracts. • Each Treasury security together with the 20 purchase contracts constitute 20 Treasury Units. • During a blackout period or following a successful remarketing, you may not create Treasury Units or recreate Corporate Units. • Unless a blackout period is occurring or there has been a successful remarketing, the holder can also transform 40 Treasury Units and an RSN of each series having a principal amount of $1,000 into 40 Corporate Units. Following that transformation, the two Treasury securities, which will no longer be a component of the Treasury Units, will be released from the pledge under the purchase contract and pledge agreement and delivered to the holder and will be tradable as separate securities. Illustrative Remarketing Timeline The following timeline is for illustrative purposes only. The dates in this timeline are based on the time periods set forth in the purchase contract and pledge agreement and the form of remarketing agreement that will be an exhibit to the purchase contract and pledge agreement. This timeline assumes that the Company will elect to conduct an optional remarketing during the first permissible time period for an optional remarketing period.
