Help with OO Model

I'm designing an OO Model for a large application, and I have some question
on how to model a particular situation; it's not directly related to C# but
rather to general OO. The applicaiton will be developed in C# 2.0 though,
which may have some influence on the OO model.
Here's what I'm trying to model:

I have a class Company, a class Publisher, a class Manufacturer and a class
Distributor.
Their relationships are as follows:
1. A Publisher is a Company
2. A Manufacturer is a Company
3. A Distributor is a Company
6. A Company can be just a distributor
4. A Company can be just a publisher or a publisher and distributor at the
same time
5. A Company can be just a manufacturer or a manufacturer and distributor at
the same time
7. A Company can be a publisher, manufacturer and distributor all at the
same time

A Publisher and a Manufacturer are very similar in that they both create a
product; however, I think of the two roles differently and would prefer to
maintain them as different entity types. I would like to see code like
Publisher.Product when I'm dealing with printed material and
Manufacturer.Product when I'm dealing with non-printed material.
On the other hand, given a Product I would like to be able to return its
creator, which could be either a manufacturer or a publisher, depending on
the kind of product.

Any insights or recommendations are greatly appreciated.
