The Oracle deal to buy out Netsuite was for $9.3 billion (all cash). They agreed to pay $109/share for all shares of Netsuite, which explains why today Netsuite is currently trading at $108.95/share. As the deal comes closer to completion, the stock will eventually creep up to the agreed upon $109. The reason it isn't trading at that price now is because of the unlikely case of the deal not going through.
You can either sell now or wait for Oracle to purchase your shares. If you wait, the shares should disappear from your account on the date of the deal closing, and be replaced with cash. If the transaction were in cash and stock, you would see the proportionate amount of cash and Oracle stock show up in your account, as stated in the deal terms.
If the shares are in a taxable account, you will have to pay long-term/short-term capital gains tax on the shares ($109 - your basis) depending on how long you have held the shares. <= 1 year is short term cap gains | > 1 year is long term cap gains. If these are held in a retirement account, the cap gains will not be treated as a taxable event.
That's about it.
