The aspect of the verb 窺う


What is the aspect in the following example for the word
[窺う](http://jisho.org/search/%E7%AA%BA%E3%81%86)?

>   2. to await (one's chance)​ _usually written using kana alone_
>
> 彼は発言の機会をうかがった。
>
> He watched for an opportunity to speak.
>
>

Does it mean:

  1. He watched for an opportunity, but it did not happen.

  2. He watched for an opportunity and he got one.

  3. Whether he had a chance to speak or not, cannot be inferred.

Is it possible to form sentences distinguishing between the situation 1. and
2. using the verb 窺う? What form would it take?




It would mean No.3 because this うかがう means "watch for an opportunity" and we
can't infer whether he had a chance to speak or not without more sentences.
