It depends on the value of the BP stock, which should be defined as of the acquisition. Let's assume your terms and closing today.

For each nwbo share you get $10 + 0.2 BMY = $10 + 0.2 * 61.33 = 22.266

45% of the value is cash. 10/22.266 rounded.
55% of the value is stock. 12.266 / 22.266.

So you have effectively sold 45 shares for $1000. Taxable gain $955.
and you have 20 shares of BMY with a cost basis of $55.
