unwelcome option

[as_99]

I am looking for another word replacing "unwelcome" in the following sentence:

This will prevent us from selling under our brand name, and this is to us an unwelcome option.
​

 

[Mer.i.am]

undesirable perhaps?

 

[Packard]

undesirable perhaps?

Depending upon degree even "unacceptable".

We need some clarification as to the exact extent of "undesireable-ness" this option is in order to give a well-reasoned reply.

That clarification is requested.
