The lead should be only one sentence long. The text should be in the past tense. Many news editors define news as something chat has already happened. The second paragraph should clarify the lead. It shouldn't contain quotes.
Quotations are appropriate for the third or fourth paragraph.
Within quotation marks, you can put any of your opinions. Write what you want to say and attribute it - it need never be said. For other quotes, chink first about what you want expressed, and then ask others for quotes along those lines. For the first page, use the letterhead stationery and for following pages, use plain white paper. Underneath the running head, note which page it is of the release.
