Is the world's most valuable Internet company having second thoughts about acquiring a stake in Time Warner's (NYSE:TWX) AOL subsidiary? In an 8-K/A filing yesterday, Google (NASDAQ:GOOG) revealed that it and AOL were extending the deadline in which the deal's details will be completed. The companies continue to negotiate the commercial agreements tied to Google's $1 billion purchase of a 5% stake in AOL.

It's easy to be suspicious. Google received a fair amount of flak for paying so much for such a small stake. Google also put up with Time Warner turning to Microsoft (NASDAQ:MSFT) and Yahoo! (NASDAQ:YHOO) during the negotiations for counteroffers -- a move that likely caused Google to pay more than it may have wanted to originally shell out.

However, Google still expects the deal to close by no later than June; the pairing just makes too much sense to abandon. AOL is the largest publisher in Google's AdSense network, the third-party publishers that broadcast the company's contextual ads. Losing AOL to a rival like Yahoo! or a fledgling ad network like Microsoft's MSN would cost Google a little in the pocketbook but far more in reputation and strategic advantage.

AOL would also lose if a negotiating stalemate causes the companies to settle for an inferior partnership. One of the few bright spots at Time Warner these past few quarters has been AOL's interactive marketing, and that's mostly Google's handiwork. As AOL seeks to beef up its portal, it can't afford to take chances on an unproven network like MSN, which is just beginning to sign up advertisers.

Google and AOL's deal will go through. These negotiations are simply an effort to work out the finer details that will make the arrangement even more positive for both companies. Good things are worth the wait; you'll just have to hold your breath for another three months at worst.
