(2) An instrument issued by a financial institution that permits the purchaser to sell, after giving required notice, a specified amount of securities from a specified issue to the financial institution on a predetermined future date or dates (the “expiration date(s)”) at a predetermined price (the “strike price”). Tender options are generally backed by a bank letter of credit or line of credit. The tender option is often originally sold as an attachment to the security. In many cases, however, the tender option may be sold separately from that security (a “detachable call”) or sold attached to other securities from the same issue. See: DETACHABLE CALL.

(3) An agreement made by the parties to a particular transaction under which the purchaser has the right to surrender the securities to the seller at a specified price on a specified future date or dates. This arrangement is distinguished from (2) above in that this tender option right is not transferable and is rarely reflected in a separate instrument, but rather is typically described only on, or as an attachment to, the transaction confirmation.

TENDER OPTION BOND – Obligations, also known as “put bonds” or “puttable securities,” that grant the bondholder the right to require the issuer or a specified third party acting as agent for the issuer (e.g., a tender agent) to purchase the bonds, usually at par, at a certain time or times prior to maturity or upon the occurrence of specified events or conditions. The put option or tender option right is typically available to the investor on a periodic (e.g., daily, weekly or monthly) basis. Typically, these securities are floating or variable rate securities, with the put option exercisable on dates on which the floating rate changes. These latter securities are often called “variable rate demand obligations,” or, colloquially, “lower floaters.” See: FLOATER; LOWER FLOATER; TENDER; TENDER AGENT; TENDER OPTION; VARIABLE RATE; VARIABLE RATE DEMAND OBLIGATION.

"upon occurrence of specified events" вполне может означать и оферту эмитента. теперь вроде душа успокоилась
_***_ Коллега, я ни в коей мере не подвергаю сомнению сказанное Вами. Просто у меня привычка - стараться "поверхностно вникнуть" (с) мой, особенно, если имеет место дискрепанс типа "оферта" vs put option.
