English to Portuguese Other Finance (general)

I have found many explanations but not a specific translation for European PT - can anyone help me?

"A net exercise is the practice of “tendering back to the company” some of the exercised shares to cover the exercise price of the option. In some cases, shares will be tendered to cover taxes as well. Many people find this more understandable when we call it “withholding shares” since the participant never actually holds the shares, the company just issues the “net shares” to the participant, hence the term “net exercise"

Could it be "opção de compra de ações com venda associada"?

Thanks!
