     CAPITATED PRICING
     Revisions & Extremities


Dear Jim:

As discussed last week,.... administratively we have had a problem with the 
additional products offered under the hip and knee contract. We proposed a 
capitated structure to simplify the tracking of cost under Revisions and 
Extremities, however, I should have touched a few additional bases internally to
insure the proper support.

After reviewing my intent, we are suggesting the attachment, to meet the intent
of capitation. You will note the pricing for Revision Hips had an increase and
we deleted the Cemented System. This allowed us to focus on a price for our
SOLUTION REVISION SYSTEM and treat all other long stems (used in revisions)
under our base discounted price list. The pricing for the Revision Knees has
been reduced for Complex Revision and various adjustments for Add-On Pricing.
The Extremity Pricing remained the same.

Jim, if this is acceptable to you, please sign below and return fax to me.

Sincerely,

/s/ William P. McIlhargey

Depuy will also provide a *% discounted invoice for the first * months of the
contract. This discount is based on Columbia/HCA obtaining total contracted
sales of $* during the first *. Should this volume not be achieved, the
discounted invoice will be discontinued.


In addition, Depuy will develop a "Capitated Program" for Columbia/HCA,
facilities, no later than the third year-end of the contract. This shared risk
approach will be structured under "Demand and Product Utilization" protocols.
