(Corrects third paragraph to say the offer is at a 22.5 percent premium to the last close of Veresen, not Pembina)
May 1 (Reuters) - Pembina Pipeline Corp PPL.TO said it would buy Veresen Inc VSN.TO in a deal valued at C$9.7 billion, including debt, creating a company that will hold oil and gas pipelines, terminal, storage and processing facilities.
Pembina said Veresen shareholders could opt to get either 0.4287 of a Pembina share or C$18.65 in cash.
That is a 22.5 percent premium to Veresen's last close, the companies said.
Pembina said it would pay as much as about C$1.52 billion in cash and 99.5 million of its stock.
