NOW THEREFORE, in consideration of the foregoing, the mutual agreements contained herein and other good and valuable consideration, the receipt and sufficiency of
which are hereby acknowledged, the parties hereto hereby agree as follows:

1.Provision and Term of Services.

(a)    Each
of the entities set forth onExhibit Aattached hereto and listed under the heading "Provider" shall provide
to the entity or entities set forth opposite its name one or more of the services listed onExhibit Aattached hereto (together with the Other
Services (as defined below), the "Services"). As used herein, the term "Provider" shall refer to any
entity providing Services, and the term "Recipient" shall refer to any entity receiving Services. The Services shall be provided in accordance with the
terms and provisions of this Agreement. Each of the parties hereto (i) shall cause each of its Affiliates that are listed onExhibit Aunder the heading "Provider" or "Recipient," as the case may be, to perform and comply with the obligations of Provider or Recipient, as applicable, pursuant to this Agreement and (ii) agrees
that each such Affiliate shall be entitled to the rights and benefits of Provider or Recipient, as the case may be, in each of clauses (i) and (ii) as if such Affiliate was a party to
this Agreement.

(b)    Provider
shall provide the Services at least at the same level as Provider provided the Services prior to the Closing Date, consistent with the manner and level of care
with which such Services were provided prior to the Closing Date.

(c)    Except
as provided in Section 3(c), each Provider shall provide the Services required to be provided by it during the term that commences on the date hereof and
ends on the date specified onExhibit A.

(d)    The
parties hereto shall use commercially reasonable efforts and cooperate with each other to facilitate an orderly and expedient transition away from each party's need
for Services as Recipient.

---

2.Compensation for Transition Services.

(a)    Subject
to Section 2(e), each Recipient shall pay the applicable Provider for the Services in accordance with the fee schedule set forth on Exhibit Battached hereto or as provided in Section 3
(d). The fee to be paid in respect of a Service (including all third party expenses
and disbursements, and any other costs and expenses to be paid to or through Provider, including payroll and employee benefit costs and expenses) pursuant to the terms of this Agreement shall be
referred to herein as the "Applicable Fee."

(b)    Except
as otherwise provided inExhibit B, the Applicable Fee for any Service shall be paid by Recipient on the
last day of each month, provided that the applicable Provider delivers an invoice for such month, which invoice shall be delivered to the appropriate Recipient no later than the twentieth
(20th) day of such month. If an invoice is not delivered to the appropriate Recipient on or before twentieth (20th) day of such month, Recipient shall pay the Applicable
Fee described in such invoice no later than ten (10) calendar days after receipt of such invoice. Such invoice must comply with all applicable tax requirements and separately describe the
amount for fees, expenses and value added tax, if any.

(c)    Recipient
shall reimburse the applicable Provider for third-party, out-of-pocket, incidental travel, lodging and food expenses incurred by
Provider in accordance with Provider's customary travel policy, within thirty (30) days of receipt of an invoice from Provider for such incidental expenses accompanied by such additional
documentation reasonably required by Recipient to verify the amount of the expense and that such expense was incurred in connection with providing the Services. Provider shall deliver such invoice and
accompanying documentation within ten (10) days following the end of the month in which such expense was incurred.

(d)    All
amounts payable by Recipient to Provider shall be paid by wire transfer in accordance with the wire transfer instructions provided by Provider to Recipient from time
to time.

(e)    Anything
in this Agreement to the contrary notwithstanding, the parties acknowledge and agree that the Applicable Fee paid for any Service is intended to equal the cost
incurred by Provider to perform such Service for Recipient (including any amounts to be disbursed to third parties in connection with the provision of any Service, including payroll and employee
benefit costs and expenses) in accordance with the provisions of this Agreement (such cost being referred to herein as the "Service Cost"). Accordingly,
the parties agree as follows:

3.Other Services.    The parties hereto acknowledge and agree that Exhibit A may not contain an exhaustive list of those
continuing and material services that one party (or an Affiliate of such party) will require from another party (or its Affiliate of such other party) to effect an orderly transition following the
sale of the Valves Business (such non-listed continuing and material services being referred to herein as, the "Other Services").
Accordingly, and anything in this Agreement to the contrary notwithstanding, the parties agree that the appropriate Provider shall continue to provide to the appropriate Recipient the Other Services
without interruption and comply with the following:

(a)    Upon
identification at any time of a service being rendered that constitutes an Other Service, Provider or Recipient thereof shall deliver a notice to the other to such
effect; it being agreed that such notice shall set forth in reasonable detail the nature and scope of such Other Service. Promptly after receipt or delivery as the case may be of such notice, Provider
shall deliver to Recipient an invoice for all such Other Services theretofor performed since the Closing Date; it being agreed that the fee for such Other Services shall equal the Service Cost for the
same, as determined in good faith by Provider (and such fee shall be the Applicable Fee for such Service for all purposes of this Agreement);

(b)    Each
of the parties hereto (i) shall cause each of its Affiliates that is Provider or Recipient, as the case may be, of Other Services to perform and comply with
the obligations of Provider or Recipient, as applicable, pursuant to this Agreement and (ii) agree that each such Affiliate shall be entitled to the rights and benefits of Provider or
Recipient, as the case may be, in each of clauses (i) and (ii) as if such Affiliate was a party to this Agreement;

(c)    Provider
shall provide Recipient each Other Service until such time as Recipient terminates such Services by delivery to Provider of notice to such effect; provided,
that (i) Recipient shall use its reasonable best efforts to effect an orderly transition of such Other Service from Provider as soon as practicable and (ii) in no event shall Provider be
required to provide Recipient with any Other Service

4

---

for more than the six (6) months after the date of this Agreement or such other period as the parties may mutually agree in writing; and

(d)    To
avoid doubt, after delivery of the first invoice with respect to any Other Service, Recipient shall continue to pay the applicable Provider the Applicable Fee for the
Other Service rendered thereafter in accordance with (and subject to) the terms of this Agreement.

4.Force Majeure.    The obligation of Provider to provide Services shall be suspended during the period and to the extent that
Provider is prevented or hindered from complying therewith by any law or governmental order, rule, regulation or direction, whether domestic or foreign, or by any cause beyond the reasonable control
of Provider, including acts of nature, strikes, lock outs and other labor and industrial disputes and disturbances, civil disturbances, accidents, acts of war or conditions arising out of or
attributable to war (whether declared or undeclared), shortage of necessary equipment, materials
or labor, or restrictions thereon or limitations upon the use thereof, and delays in transportation. In such event, Provider shall give notice of suspension as soon as reasonably practicable to
Recipient stating the date and extent of such suspension and the cause thereof and Provider's best estimate of the date on which it will be able to resume the performance of its obligations. In
addition, Provider will use commercially reasonable efforts during any such suspension to keep Recipient informed as to the progress of removal of the cause of such suspension. Provider shall resume
the performance of such obligations as soon as reasonably practicable after the removal of the cause and Provider shall so notify Recipient, and Recipient shall not be liable for payment of Applicable
Fees for any Service for the period in which such Service could not be provided pursuant to this Section 4.

5.Compliance With Law.    The parties shall undertake to provide Services in accordance and in adherence with all laws and
governmental rules, regulations and orders applicable at the place where Services are rendered, including without limitation, data protection and retention regulations.

6.Confidentiality.    Each party hereto shall, and shall ensure that its Affiliates shall maintain the confidentiality of all
data, information, reports, studies, suggestions and other materials regarding the other parties hereto and their Affiliates with the same level of care and in accordance with the same procedures
Provider uses with respect to its own such data, information, reports, studies suggestions and other similar materials.

7.Limitation of Liability; Indemnification.

(a)    Provider
shall not have any duties or responsibilities hereunder other than those specifically set forth herein, and no implied obligations shall be read into this
Agreement. Neither Provider nor any of its respective officers, directors, employees, agents, attorneys-in-fact or Affiliates (collectively, the
"Provider Parties") shall be liable for any action taken or omitted to be taken by it or such person under or in connection with this Agreement, except

obligations hereunder.

(b)    In
Centerpulse USA's capacity in administering health and welfare benefits for employees of CMI for service dates and periods (or partial periods) from and after the
Closing Date, neither CMI nor SNIA shall look to nor consider Centerpulse USA or its Affiliates to be an insurer in any capacity of the benefits so administered. CMI, and not Centerpulse USA, is
liable for the benefit claims submitted by employees of CMI or any of the Target Companies during the term of this Agreement for benefits payable in respect of service dates or periods from and after

responsibility is to administer such payroll on behalf of CMI.

(together with their Affiliates signatory hereto) on the one hand and, Providers (together with their Affiliates signatory hereto) on the other hand
(collectively, "Indemnifying Parties"), shall each jointly and severally indemnify and hold harmless the other (collectively,
"Indemnified Parties") from any Losses incurred by any Indemnified Parties arising out of the gross negligence, fraud, willful defaults or misconduct of
any Indemnifying Parties with respect to this Agreement.

8.Notices.    Any legal notice, demand or other communication required or permitted to be given by any provision of this
Agreement (each a "Notice") shall be in writing and shall be deemed to have been properly given or served only if addressed to a party hereto at its
address set forth onExhibit Aattached hereto, and if delivered (A) by hand, (B) by certified mail, return receipt requested,
(C) by overnight commercial carrier or (D) by telefax transmission with confirmation of receipt. All such communications shall be deemed to have been properly given or served
(i) if by hand, when received, (ii) if by mail, on the date of receipt or of refusal to accept shown on the return receipt, (iii) if by overnight commercial carrier, on the date
that is one business day after the date upon which the same shall have been delivered to such overnight commercial carrier, addressed to recipient, with all shipping charges prepaid, providedthat the
same is actually received (or refused) by recipient in the ordinary course and (iv) if by telefax, on the date sent with
transmission confirmed.

9.No Third Party Beneficiaries.    This Agreement shall be binding upon and inure solely to the benefit of the parties hereto
and their permitted successors and assigns, and each Provider and each Recipient shall be entitled to enforce its respective rights under this Agreement against Provider or Recipient of the Service in
question.

10.Governing Law.    This Agreement shall be governed by, and construed in accordance with the laws of the state of New York.
The parties hereto submit to the jurisdiction of any state or federal court sitting in New York for the purpose of any suit, action or proceeding arising out of this Agreement.

11.Entire Agreement.    This Agreement, together with the Purchase Agreement and the Schedules and Exhibits thereto and the
Schedules and Exhibits hereto, sets forth all of the promises, covenants, agreements, conditions, and undertakings between the parties hereto with respect to the subject matter hereof and supersedes
all prior and contemporaneous agreements and understandings, inducements or conditions, express or implied, oral or written. The Schedules and Exhibits to this Agreement constitute an integral part of
this Agreement.

12.No Assignment.    This Agreement shall not be assignable (directly or indirectlyby operation of law or
otherwise) by either party hereto without the prior written consent of the other party hereto; and any attempt to assign this Agreement in violation this provision shall be void. This Agreement shall
be binding upon and inure to the benefit of the parties hereto and their respective successors and permitted assigns.

13.Waiver.    No provision of this Agreement may be waived except by an instrument in writing signed by the party sought to be
charged with the effect of such waiver. The failure of a party to this Agreement to assert a right or exercise a remedy hereunder shall not waive such right or remedy or any future rights or remedies.

14.Status.    For purposes of this Agreement, Provider is, and will be deemed to be, an independent contractor only and not an
agent, joint venturer, partner, or representative of Recipient. Neither Provider nor Recipient may create any obligations or responsibilities on behalf of or in the name of the other hereunder.

parties intend that there shall be added as a part of this Agreement a provision as similar in terms to such invalid or unenforceable provision as may be valid and enforceable, so as to effect the
original intent of the parties to the greatest extent possible.

17.Survival.    Except as may be expressly provided in this Agreement, the provisions of Section 2(a) and
Section 6 through 18 (inclusive) shall survive the term during which any Service hereunder is required to be performed.

disbursements attached hereto asExhibit D, Recipient shall deposit into the Bank Account an amount equal to the gross payroll total from the previous payroll period (including Recipient's portion
of FUI, SUI, FICA and Medicare) plus the gross employer 401(k) liability from the previous payroll period. Provider shall provide such aggregate amount to Recipient in the form ofExhibit Cas soon
as practicable after the applicable previous payroll period. For example, if the payroll disbursement date is January 31, 2003, Recipient must deposit the fee into the Bank Account no later than January 21, 2003.
