How can actual credit examples be used for this speech?

The ability to express one’s thoughts without prior preparation is a valuable asset. Poise, self-confidence, and organization of facts are elements necessary for an effective impromptu speech.
Participants in the Impromptu Speaking Event will be given a current business topic. One (1) 4-by-6 index card will be given to each participant and may be used during the preparation and performance. Information may be written on both sides of the card. Participants must furnish their own pens and pencils. No reference materials may be brought to or used during the preparation or presentation. Participants will have a lectern to use for their speech but no microphone will be provided.
Participants will be allowed ten (10) minutes to prepare their speeches prior to appearing before the judge. Any notes made during the preparation time may be used when speaking. The note card must be submitted to the teacher/event coordinator at the conclusion of the speech. The speech should be four (4) minutes in length. A timekeeper will stand at three (3) minutes.
When the speaker is finished, the time used by the participant will be recorded, noting a deduction of five (5) points for any time under 3:31 or over 4:29 minutes.
