West who opened 2   rebids 3 NT after East's 2   negative response to  show his  balanced hand with  25-27 points.

After 2C opener's 2NT or 3NT rebid all sytems are on. This means that responder's

3 is Stayman
3 is transfer to heart
3 is transfer to spade
3 is transfer to minors
3NT to play
4 Gerber

After 2C, opener's 4NT shows 28-30 points, responder's 5+ points is enough for slam. So, responder must not use above conventions after 4NT...

West opens 2, East makes 2  negative (or waiting) response. Then, West rebids 2  to show his 5-carded suit. Now responder will bid the cheapest minor (in this case 3) that he is REAL negative..

Note: As you noticed in our system 2 is first negative bid and cheapest minor after opener's response is second negative bid. In order to rectify this some partners uses 2 response to 2 opening as real negative (0-4 points). In that convention, 2NT bid by responder replaces 2 response in our system....

5.4  Rebids by Responder

If 2 was "Waiting"

Responder's rebids depend on opener's rebids.. 
If opener's rebid is 2NT or 3NT, responder can use Stayman or transfer conventions to find the best contract with game points.
If opener's rebid is 2NT, responder can bid 3NT with 2-4 points..
If opener's rebid is 2NT, responder can bid "Pass" with less than 2 points..

If opener's rebid is in a suit, responder bids 2NT without support..

If 2 was "Negative"

Suppose you have this hand
54
543
5432
5432

Partner opened 2C, you responded 2D and opener rebid 2S..
What will be your response as responder?
Pass : Partner can be able to make a game alone.. Your pass will prevent it..
3S : Partner can jump to Slam or game after 3S
2NT : 2NT with this hand! you are kidding!...
So, Convention makers invented "second negative" convention to help the people who are suffering with a real negative hand like above.. Any cheapest minor suit by responder is second negative after 2D response.... like 2C-2D-2S-3C or, 2C-2D-3C-3D or, 2C-2D-2H-3C etc...
