I think few people would link out on the page on which they hope to finalise a deal.
I have several trainees building content and I always ask them to try to find at least one good high quality source to link out to for every info-content page they make. If nothing exists on-line I tell them to mention book/title/author. (mostly they are pages of which some data was used anyway).

I do not ask a reciprocal link back. I just think it makes sense.

I guess it depends on the industry your in, but in anything semi-scientific I think it just looks better/more authoritative if there are sources mentioned.

This set-up also helps when asking for one-way links. It is often extremely difficult to get links from governmental and edu sites because they have a policy of not linking to .com's and/or commercial sites. Showing your "independant strength" by not failing to link out to recognisable authorities helps in these cases.

Now when addressing possible algo-consequences, check the research papers.
Many mention link hoarding, link sinks or mutual admiration societies as leaning towards spam. As mentioned above, the web needs links, the search engine's algos need them and even non-outlinking webmasters need them :).

Outside Teoma, I have not checked the consequences, but I would be suprised if the major search engines would not build in some "thank you we will let this page rank higher" for a good link out.

Not linking out, except for your link farms or reciprocal links, also makes your site an identifiable non authoritative hub or authority, to be placed on the same heap as your link partners.
