In Stored Proc - How Do I Find The Next Key Value (integer) And Use It To Populate A Field In The New Record.

Currently I have the following stored procedure which simply adds a new row in my SQL Express 2005.
 What I want is that -
1). before inserting the record find out the new ID (primary key) value. (ID is automatically a sequential integer generated by SQL Server)

2). and set COMPANY_ID = (new) ID
 
Any thoughts?
 
Thanks
 
ALTER PROCEDURE usp_tbl_Company_Insert
    @Company_ID int,
    @Name varchar(200),
   
AS
<FIND THE NEW ID of the new row in the database> 
@Company_ID = (new ID) 
 
INSERT INTO tbl_Company (Company_ID, Name,)
VALUES (@Company_ID, @Name)
