Schedule A

Chronic Outpatient Therapy Agreement

General Terms and Conditions

The following general terms and conditions apply to the purchase of the NxStage System One (“System”), consisting of either a Cycler, Warmer and Stand, or a Cycler and PureFlow SL (Cabinet and Control Unit), as the case may be, System cartridges and fluids (“Supplies”), and related products and services for use in chronic outpatient therapy (“Related Products”). The System, Supplies and Related Products sold hereunder are referred to collectively as “Products”.

1. PURCHASES

The purchase of Supplies and Related Products must be initiated by purchase orders or NxStage System Patient Orders (“Patient Orders”; form available upon request), signed by the prescribing physician for the named patients who will receive chronic therapy. All System orders must be initiated by purchase orders. If the terms and provisions of the purchase order or Patient Order conflict with or are in addition to the terms of this Agreement, the terms of this Agreement shall control.

2. PRODUCTS AND PRICING

A. Pricing for Monthly Dialysis Supplies is outlined in Schedule B-1. Pricing for the purchase of System equipment and ancillary/replacement supplies is outlined in Schedule B-2. Pricing for delivery services is outlined in Schedule B-3. The prices on Schedules B-1 and B-2 are fixed through [**] and are thereafter subject to [**] as described in paragraph B below. The pricing for the delivery services in Schedule B-3 may be amended at any time at NxStage’s discretion with [**] days advanced written notice to Customer.

B. Starting [**], NxStage shall have the right to [**] the prices for each Product (as identified on Schedules B-1 and B-2) if Customer’s Active NxStage Chronic Patient Census (as defined in paragraph C below) is less than [**] as measured [**]. For the sake of clarity, if Customer’s Active NxStage Chronic Patient Census is equal to or greater than [**] as measured [**], then NxStage shall not have the right to [**].

C. For purposes hereof, the term “Active NxStage Home Patient Census” is defined to mean the Authorized Customer Locations’ aggregate number of [**] then prescribed to receive, and receiving, dialysis with the NxStage System One. The Active NxStage Home Patient Census shall not include patients prescribed to receive therapy with the NxStage System One (i) in a nursing home or an in-center self-care setting or (ii) in connection with an evaluation of more frequent therapy, home therapy or the System One (such as under NxStage’s “Experience the Difference” program). In addition, the Active NxStage Home Patient Census shall not include (a) [**] acquired by Customer or any Authorized Customer Location on or after the Second Amendment Effective Date (1) through the purchase of facilities which have, or did have, any type of program with NxStage with respect to the purchase, sale or rental of the System One for home use during the [**] prior to the closing date of the acquisition (each, an “Acquired Site), or (2) under any management contract, joint venture or other similar transaction entered into subsequent to the Second Amendment Effective Date with any facility which has, or did have, any type of program with NxStage with respect to the purchase, sale or rental of the System One during the [**] prior to the effective date of any such management contract, joint venture or similar transaction (each, a “Management Contract Site”) and (b) any patients added to an Acquired Site or Management Contract Site after the closing date of the acquisition or the effective date of the management contract, joint venture or other similar transaction, respectively. For the sake of clarity, both existing and new patients in Authorized Customer Locations existing as of the Second Amendment Effective Date that become joint venture locations after January 1, 2014 shall continue to be included in the Active NxStage Home Patient Census.

D. NxStage will on occasion supply Products sourced from other suppliers pursuant hereto. NxStage reserves the right to supply its own Products, once the same are commercially available, or to change the supplier of these Products from time to time. NxStage expects to, but has no obligation to, make additional products available for purchase by Customer from time to time. NxStage, therefore, reserves the right to amend the Schedules hereto to include additional product offerings with advanced customer notification.

E. The Products and services listed in Schedules B-1 through B-3 are subject to discontinuation in NxStage’s sole discretion or due to Force Majeure events.

3. LIMITATIONS ON SALE AND USE

All Products are to be used by the Customer in the continental United States at Authorized Customer Locations (as listed in Schedule D) and are not to be transferred, remarketed or resold. Notwithstanding the foregoing, Customer may (i) transfer Products to a third party in connection with the sale of an outpatient dialysis clinic by Customer which includes Products then in use by such clinic’s patients in the assets that are sold, and (ii) transfer, resell, and, in the case of Systems, rent Products to Authorized Customer Locations that are (a) independent dialysis clinics that have entered into management contracts with Customer covering the purchase of products, including the System One, and (b) dialysis clinics held by Customer in a joint venture structure, subject, in the case of subpart (i) and (ii) hereof, to NxStage’s prior written consent, which shall not be unreasonably withheld. Products are to be used only for chronic patient therapy for treatment of named patients or for training.

[**] completed Patient Orders and a purchase order for [**] Systems are required for a new site/facility startup. Additionally, the parties must agree to amend this Agreement, according to the procedures set forth in Section 23, to add a new site/facility as an Authorized Customer Location (as defined in Schedule D hereto). Customer agrees that simultaneous with the execution of this Agreement, Customer shall purchase, at the pricing set forth in Schedule B-2, all Systems that have been provided to [**] clinics, and that all Product purchases for such clinics shall be made pursuant to this Agreement from and after the Effective Date.

4. SHIPPING

Shipping is [**]. Monthly Dialysis Supplies (as that term is used in Schedule B) shipment quantities will be based on the prescribed frequency (as indicated in the Patient Order) and inventory needs of the patient, as reported by the patient to NxStage Customer Service. All prices for Monthly Dialysis Supplies (provided such Supplies are part of either (i) a patient’s standard delivery quantities pursuant to Patient Orders, or (ii) a patient’s travel delivery consistent with the terms hereof and as documented on a NxStage System One Vacation and Travel Form (copies of which are available on request)), include shipping costs to Customer’s patients’ homes or designated travel destination in each case in the 48 continental states via common carrier of NxStage selection unless otherwise stated, and include one patient delivery each [**] weeks, based on NxStage’s then-standard delivery policies for that geographical area. For all other deliveries, shipping costs will be prepaid by NxStage and added to the Customer’s invoice. NxStage shall use reasonable diligence to ensure that Products are shipped according to Customer’s delivery requirements. Any extra charges for special services are prepaid by NxStage and added to the Customer’s invoice. The schedule of special services is outlined in Schedule B-3.

If an expedited shipment (requiring delivery in less than [**] business days) must be made at Customer’s request, Customer agrees to pay for all incremental Product-shipping charges in excess of what standard shipping costs would be for unexpedited shipment. Without limiting the foregoing, Customer agrees that its patients are expected to accurately report their levels of Supplies inventory to NxStage Customer Service on a monthly basis. If patients fail to do this, and require expedited shipments of Supplies to perform dialysis therapy at their prescribed frequencies, Customer agrees to pay for all incremental Product-shipping charges in excess of what standard shipping costs would be for unexpedited shipment. NxStage reserves the right to charge Customer (or to increase Monthly Dialysis Supplies pricing) for Supplies consumption above the applicable prescribed frequency, as measured on a calendar monthly basis, or if usage is above standard usage levels.

Customer must notify NxStage Customer Service in writing of any irregularity in a Product shipment within the later of [**] business days of receipt of the shipment or [**] business days discovery of a concealed defect in such shipment. All evidence of shipping damage or over- or under- shipment should be noted on the carrier’s freight xxxx and the carrier should countersign the document. In the absence of timely written notice, acceptance will be conclusively presumed. NxStage shall use reasonable efforts to replace goods damaged in transit and to remedy Product delivery shortages within [**] business days of receiving notice thereof from Customer.

5. VACATION/TRAVEL SUPPLIES (Including Premixed Bags for PFSL Patients)

Monthly Dialysis Supplies prices are extended to Customer’s traveling patients when traveling within the 48 continental states as long as NxStage is given at least [**] business days’ notice of the change in delivery site, NxStage receives a prescription using the NxStage System One Vacation and Travel Form from the patient’s physician requesting travel delivery at least [**] business days in advance of the requested change in delivery site, and NxStage is not required to alter standard case shipping volumes to satisfy special travel/vacation delivery requirements. This benefit may be used for no more than [**] trips per patient; for a maximum of [**] weeks per patient in total annually. Requests for travel/vacation delivery in excess of [**] trips or [**] weeks annually, to locations outside of the 48 continental states, in non-standard shipping volumes, or which are made with insufficient notice, shall be subject to approval from NxStage and may be subject to additional charges. NxStage shall act in good faith to make additional travel/vacation deliveries to Customer’s patients at no additional charges, and shall give due consideration to vacation time unused by Customer’s other patients. Customer’s patients’ Monthly Dialysis Supplies shipments shall be adjusted to account for all travel Supplies delivered. NxStage will not arrange for delivery of Systems. Customer is responsible for transporting Systems according to the shipping directions provided by NxStage in the device Operator’s Manuals and other supplements as required, and Customer shall be responsible for any damages to Systems as a result of any improper shipping by Customer or its patients.

Moreover, an allotment of PureFlow Express Premixed Dialysate bags will be made available to Customer for distribution to its NxStage PureFlow SL patients [**] to allow for vacation, travel, and other usage. Allotments shall be made on an Authorized Customer Location basis. The initial allotment balance per Authorized Customer Location (“Balance”) shall be equal to [**] cases of PureFlow Express Premixed Dialysate multiplied by [**] such location’s patients prescribed to receive PureFlow SL Monthly Dialysis Supplies as of the Effective Date. Thereafter, the Balance shall be recalculated at the end of each calendar month per Authorized Customer Location according to the following formula:

• Add: [**] cases of Premixed Dialysate multiplied by [**] such location’s patients then prescribed to receive and receiving PureFlow SL Monthly Dialysis Supplies at home at the start of that calendar month

• Add: [**] cases of Premixed Dialysate multiplied by [**] such location’s [**] PureFlow SL [**] at home during that [**] (adjusted, as appropriate, for [**])

• Subtract: Actual shipments during that calendar month of Premixed Dialysate, in cases, to such location’s patients then prescribed to receive and receiving PureFlow SL Monthly Dialysis Supplies, not including cases purchased as part of an initial reserve inventory shipment and as adjusted in good faith by NxStage to exclude cases shipped to support reported PureFlow SL reliability events.

If the calculated Balance is negative, NxStage shall xxxx Customer for such negative Balance at pricing listed in Schedule B and the Balance will be [**] to start the subsequent calendar month. Any positive Balance shall be carried to the subsequent calendar month, provided such positive Balance, in cases, will never exceed the number of such Location’s patients then prescribed to receive and receiving PureFlow SL Monthly Dialysis Supplies at the end of that month multiplied by [**]. Balance information shall be provided to Customer upon Customer’s request.

6. PAYMENT

Upon successful credit review by NxStage, terms will be [**]. Payments made more than [**] days after the stated term will be subject to a past due service charge of [**] per month (or the highest rate permitted by applicable law, whichever is less), except for any portion of an invoice disputed by Customer in good faith. Any invoice dispute must be made by Customer in good faith. Customer must notify NxStage of any invoice disputes in writing within [**] days of its receipt of an invoice, and the parties shall take all commercially reasonable efforts to resolve any billing disputes within [**] days.

If Customer fails to pay its undisputed balance within [**] days of the date of the invoice, NxStage may, at its option, upon [**] days written notice and Customer’s failure to cure within such [**] days, terminate this Agreement and any other agreements between NxStage and Customer or modify their payment terms.

7. DISCOUNTS AND REBATES

Discounts and rebates earned under this Agreement are “Discounts or Other Reductions in Price” to Customer under 42 U.S.C. §1320a-7b(b)(3)(A) of the Social Security Act, and must be properly reported on applicable Medicare and Medicaid cost reports. Customer should retain a copy of this Agreement and all related notices and communications from NxStage, together with invoices hereunder (which will indicate that a discount or end of period rebate may apply) and permit agents of the U.S. Department of Health and Human Services or any state Medicaid agency access to such records upon request.

In order to assist Customer’s compliance with such obligations, NxStage shall fully and accurately report all discounts on the invoices or statements submitted to Customer, or where the value of a discount is not known at the time of sale, NxStage shall fully and accurately report the existence of the discount program on the invoices or statements submitted to Customer and when the value of the discount becomes known, provide Customer with documentation of the calculation of the discount identifying the specific Products to which the discount will be applied. At Customer’s request, NxStage shall also provide Customer with any other information necessary for Customer to comply with such obligations.

8. TAXES

Quoted prices do not include sales, use, excise or similar taxes. Customer agrees to pay promptly any and all applicable taxes, assessments, or other charges levied or assessed on or with respect to the acquisition, possession, or use of any Products, and shall reimburse NxStage if NxStage has paid such taxes, excluding, however, any taxes on or measured by NxStage’s net income.

9. BILLING, THERAPY DISCONTINUATION, AND HOSPITALIZATION CREDITS

Monthly Dialysis Supplies are billed on a monthly basis, by calendar month at the beginning of the calendar month. Each patient shall be designated by prescription as either a PureFlow SL patient or an Express patient. Supplies outside of the Monthly Dialysis Supplies for PFSL patients (e.g., PureFlow Express premixed dialysate, except for the provisions of Section 5) and for Express patients (e.g., PFSL supplies) shall be billed independently according to pricing in Schedule B-2.

For Supplies under the Monthly Dialysis Supplies, billing will commence when patient initiates therapy (as noted on the Patient Order), and will continue until written notification of discontinuation of therapy is received (using the NxStage Patient/Customer Status Form, available upon request). The monthly billing amount will be adjusted only (i) during the first month of therapy (to account for the portion of the month prior to a patient’s therapy start date), or (ii) in the event of documented hospitalization leading to missed NxStage therapy treatments.

Except as provided below, in the case of documented hospitalizations, no credit shall be given for missed treatments, for any reason, including patient noncompliance. In the event of a documented hospitalization, [**].  Documentation of hospitalizations must be provided (using the NxStage Patient/Customer Status Form) to NxStage within [**] days of the date of discharge in order to be eligible for such a pro-rated credit. Monthly Dialysis Supplies shipments will be adjusted appropriately to account for missed days of therapy for any reason, and Customer’s patients are expected to accurately report their inventory of Supplies to avoid over-deliveries or product shortages.

It is the Customer’s responsibility to retrieve and/or dispose of all unused Supplies at patient discontinuation. No credit will be issued for any Monthly Dialysis Supplies retrieved by Customer that have not been invoiced. Supplies retrieved that have not yet been invoiced must either be returned to NxStage, at NxStage’s expense or used by Customer. Once such supplies are assigned for use, NxStage shall invoice Customer for such supplies, and adjust subsequent deliveries. If retrieved supplies were invoiced, NxStage will apply, at Customer’s request, a credit against future Monthly Dialysis Supplies orders, as set forth in Patient Orders, if the retrieved Supplies are used for a future patient, are unexpired, and are consistent with the future patient’s prescription. The amount of the credit applied shall be based upon the number of treatments that can be fully performed with such retrieved Supplies. Customer may request that NxStage retrieve the System and Supplies and return them to the center at the charges outlined in Schedule B.

[**].

10. MAINTENANCE AND UPGRADES

At its option, NxStage may conduct routine maintenance on the System(s) and any other equipment shipped to Customer under this Agreement. Customer shall provide NxStage with reasonable access to these devices during Customer’s normal business hours, Monday through Friday (not including holidays), to conduct such maintenance, at NxStage’s request upon reasonable prior notice. As part of an ongoing maintenance program, NxStage may elect to install reasonable Product upgrades, at no cost to Customer. NxStage does not, however, guarantee that any upgrades will be installed on Products shipped to Customer under this Agreement.

11. WARRANTY/SERVICE

NxStage warrants the Systems, Supplies and Related Products according to the terms outlined in Schedule C. THESE WARRANTIES CONTAIN CUSTOMER’S SOLE REMEDIES AND ARE EXPRESSLY IN LIEU OF ALL OTHER WARRANTIES, INCLUDING IMPLIED WARRANTIES OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE AND NONINFRINGEMENT.

12. RISK OF LOSS (only for items to which NxStage retains title)

Customer is entirely responsible for any loss of or damage to any property or equipment provided to Customer hereunder and to which NxStage retains title from whatever causes, except for normal wear and tear and defects in materials and workmanship (an “uncovered loss”). If NxStage determines that any such property or equipment which has an uncovered loss is repairable, Customer will pay NxStage’s cost of repair or replacement and NxStage will either repair the damaged device or replace it with another device in good working order, which may or may not be new. If NxStage determines that a device, which has an uncovered loss, is not repairable, Customer will pay NxStage the [**] for that device [**] by NxStage, return the device to NxStage, and NxStage will provide a replacement device in good working order. If a device is lost, discarded or stolen, Customer shall pay NxStage the [**] for that device and NxStage shall have the discretion to either terminate this Agreement, or to provide Customer with a replacement device. With the exception of the Cycler Log Files, and any related computer, or in the context of a service swap, NxStage agrees that it shall not ship items to Customer to which NxStage will retain title without Customer’s prior written consent, which shall not be unreasonably withheld.

13. CUSTOMER SERVICE

NxStage Customer Service is available during NxStage’s normal business hours, Monday through Friday (not including holidays), to support its customers’ product ordering needs. NxStage provides 24/7 technical support for its customers’ System servicing needs. Clinical and technical questions raised by Customer’s users with NxStage Customer Service will be referred, if possible, to Customer’s facility, to ensure consistency in patient care and adherence with Customer’s policies and procedures.

14. TRAINING

At initiation of a new Authorized Customer Location, Customer agrees to use reasonable commercial efforts to select at least [**], and preferably [**], staff [**] to serve as Customer’s expert user of the Products and trainer of subsequent staff, and shall use reasonable commercial efforts to schedule appointed staff and at least [**] to be available for treatment during the Authorized Customer Location’s start-up week. Provided the above, NxStage agrees to provide [**] days of on-site in-servicing and support training at each center start-up, and a [**] “Training Package” of [**] cartridges for each center start-up for non-clinical use solely in connection with training. At its option, Customer may purchase additional on-site NxStage clinical educator days for $[**]/day, plus reasonable travel and lodging expenses, with a valid purchase order.

15. ACCESS TO SYSTEM DATA

The System may have an internal computer that records all Systems operations, such as alarms and Cycler control panel touches (“Cycler log files”). Customer agrees that, even with purchased Systems, the Cycler log files and the computer containing them, are the property of NxStage, agrees not to tamper with or destroy Cycler log files or the computer, and to make available such log files and computer to NxStage at reasonable times within [**] hours of NxStage’s request. NxStage shall keep this information confidential and shall use it for continued product improvement and service. For so long as Systems are in use by Customer for chronic outpatient therapy, NxStage hereby grants

Customer an irrevocable license to access and use the treatment specific data (e.g., flow rates, treatment times, alarms) contained in all Cycler Log Files created in connection with Customer’s patient treatments using Systems purchased by Customer; provided that NxStage shall have no obligation to summarize such data or otherwise manipulate such data on Customer’s behalf; and provided further that NxStage shall have no obligation to service the computer generating such Cycler Log Files beyond [**] years after the original System purchase date. Customer understands that such data is not automatically transmitted from Cyclers to NxStage and that Customer is responsible for ensuring the transmittal of such data to NxStage. Customer further understands that NxStage can not guarantee the completeness of such data, as the same may be impacted by power outages, improper connections between the Cycler and the computer that records the Cycler Log Files, or other disruptions in Cycler or computer operations. Customer acknowledges and agrees that it has no expectation that the Cycler Log File information will be analyzed by NxStage.

Customer understands that Cycler Log Files do not presently capture patient clinical data (defined to mean patient physiologic parameters such as blood pressures, hear rates, URRs, and Kt/Vs) (“Patient Clinical Data”). NxStage agrees that all of Customer’s Patient Clinical Data shall be the property of Customer but that NxStage may continue to use such data learned by NxStage in the ordinary course of its business for complaint investigations, product improvements and service.

16. FORCE MAJEURE

NxStage or Customer will not be liable for any failure to perform under this Agreement, including any failure or delay in delivering Products, that is caused by raw material shortages, manufacturing or supply problems, delivery or labor problems, strikes, fires, floods, riots, acts of war, lock-outs, judicial or administrative orders, interruptions in transportation, inability to obtain materials upon reasonable prices or terms, or causes beyond NxStage’s control. In such events, NxStage shall allocate Products and training capacity to Customer consistent with Customer’s then current share of NxStage’s Products in the field, and agrees that, during the duration of any inability to supply, Customer shall be relieved of its Minimum Purchase Requirements (as set forth in Schedule B-2) to the extent such inability to supply directly prevents Customer from satisfying these obligations. Such obligations shall be reinstated upon the conclusion of an inability to supply, with such adjustments thereto as mutually agreed to by NxStage and Customer so as to reflect the impact of such inability to supply on Customer’s patient volumes.

17. CONFIDENTIALITY

NxStage and Customer agree not to disclose [**] regarding this Agreement to any other party.

18. USE OF NAME

Neither party will use the other party’s name in promotional materials without the other party’s consent. NxStage may refer to Customer as a customer of NxStage when asked, or if required by law. Additionally, notwithstanding the foregoing, NxStage may refer to Customer on NxStage’s website under a “Find a Provider” or similar feature.

19. LIMITATION OF LIABILITY

IN NO EVENT SHALL EITHER PARTY HAVE ANY LIABILITY TO THE OTHER PARTY UNDER THIS AGREEMENT FOR ANY CONSEQUENTIAL, SPECIAL, INCIDENTAL, PUNITIVE, OR OTHER INDIRECT DAMAGES. In addition, in no event will NxStage’s total liability to Customer exceed the [**] NxStage by Customer for all Systems purchased hereunder.

20. INSURANCE

NxStage shall, during the term of this Agreement and for a period of six (6) years following the termination or expiration of this Agreement, maintain product liability insurance for the Products. The insurance must have minimum limits of at least five million dollars ($5,000,000) per occurrence.

NxStage shall, during the term of this Agreement and for a period of three (3) years following the termination or expiration of this Agreement, maintain comprehensive general liability insurance and broad form contractual liability insurance to cover claims related to its premises and operations, personal injuries, property damage and independent contractors. The insurance must have minimum limits of at least one million dollars ($1,000,000) per occurrence.

Simultaneously with the execution of this Agreement, NxStage shall provide to Customer certificates of insurance, issued by a company or companies reasonably acceptable to Customer, evidencing the existence of the insurance required to be maintained pursuant to this Section 20 and providing that Customer is an additional insured under such policies. NxStage agrees to provide at least thirty (30) days notice of the expiration or cancellation of any insurance required by this Section 20.

21. INDEMNIFICATION

NxStage agrees to indemnify, defend and hold harmless Customer, its officers, directors, employees, agents, successors and assigns (each, a “Customer Indemnity”) from any and all third party claims, demands, actions, losses, proceedings, expenses, damages, liabilities, costs, expenses (including reasonable attorney’s fees and costs) and judgments (“Loss”) arising out of (i) injury or damage caused by any design or manufacturing defect of the Products covered under this Agreement when such Products are used in accordance with NxStage User’s Guides and package inserts, (ii) the negligent acts or omissions of NxStage or its employees or agents, (iii) any claim or allegation that the use of the Products in accordance with the terms of this Agreement and with then-current Product user’s guides or instructions for use infringes upon any United States intellectual property right of any third party, and (iv) any breach by NxStage of its representations, warranties and covenants hereunder; provided in each case that such indemnity shall not apply to the extent any Losses arise out of the negligence or willful misconduct of any Customer Indemnity or its patients.

Customer agrees to indemnify, defend and hold harmless NxStage, its officers, directors, employees, agents, successors and assigns (each, a “NxStage Indemnity”) from any and all Loss arising out of (a) the negligent acts or omissions of Customer or its employees or agents, or patients, or (b) any breach by Customer of its representations, warranties and covenants hereunder; provided in each case that such indemnity shall not apply to the extent any Loss arises out of the negligence or willful misconduct of any NxStage Indemnity.

22. CUSTOMER REPRESENTATION

Customer warrants and represents that this Agreement and all purchase orders, Patient Orders, amendments, and other documents provided hereunder has been and shall be duly executed by its duly authorized officers or agents, and that NxStage shall be entitled to rely on and perform under all such documents. Customer further represents that Fresenius USA Marketing, Inc. is the primary entity through which Fresenius Medical Care AG & Co.

Schedule C

Chronic Outpatient Therapy

Warranty, Service, Recalls

Warranties

For a period of [**] following Customer’s receipt of Products under this Agreement, NxStage warrants that (a) the Products shall be free from defects in material and workmanship when delivered, and (b) the Products are fit for the indications described in their User’s Guides and package inserts when used in accordance with the instructions for use provided in such User’s Guides and package inserts. Unless such Products are used in accordance with such instructions and indications, this warranty is void and of no force or effect. NO OTHER EXPRESS OR IMPLIED WARRANTY EXISTS FOR ANY PRODUCTS, INCLUDING ANY WARRANTY OF MERCHANTABILITY, FITNESS FOR A PARTICULAR PURPOSE, AND NONINFRINGEMENT. The warranties set forth herein shall extend only to the original purchaser. These warranties are not assignable or transferable. If, however, Customer transfers or resells Products as permitted by Schedule A, Section 3, NxStage will offer to the new owner of the transferred Products any time that remains under the [**] warranty for the transferred Products pursuant to a separate agreement between such new owner and NxStage.

NXSTAGE’S SOLE OBLIGATION AND CUSTOMER’S SOLE REMEDY FOR BREACH OF ANY WARRANTY PROVIDED HEREUNDER SHALL BE LIMITED TO PRODUCT REPAIR OR REPLACEMENT, AT NXSTAGE’S OPTION AND EXPENSE. ALL WARRANTIES SHALL BE VOIDED IF (i) the Product has been repaired or serviced by persons other than NxStage personnel or its authorized representatives, (ii) the replacement or repair is required due to the misuse or abuse of the Product, as determined by NxStage, (iii) the System is used with non-NxStage disposable products, (iv) the replacement or repair is required for reasons other than defects in materials and workmanship or, in the case of Systems, normal wear and tear, as determined by NxStage, or (v) the product is not used in accordance with its instructions for use, as determined by NxStage. IN NO EVENT SHALL NXSTAGE BE LIABLE FOR ANY CONSEQUENTIAL, SPECIAL, INCIDENTAL, PUNITIVE OR OTHER INDIRECT DAMAGES ARISING OUT OF THIS AGREEMENT OR THE PERFORMANCE OF SERVICES AND/OR SUPPLY OF PRODUCTS HEREUNDER.

Service

System equipment may only be serviced by NxStage at this time. If a System in active use by Customer needs to be returned for service, NxStage will swap the System requiring service with another System in good working order, which may or may not be new, [**] to Customer except as set forth below. To obtain service on System equipment, Customer shall follow the procedure set forth below. With respect to each System purchased by Customer, including those purchased prior to the Effective Date (e.g., pursuant to an expired or terminated contract), NxStage shall charge fees for NxStage equipment service and maintenance (“Service Fees”) on such System in accordance with the table and terms set forth below. For the sake of clarity, if Customer transfer or resells System equipment as permitted by Schedule A, Section 3, then (a) Customer’s [**] will be the [**] that NxStage will use to calculate service fees for the [**] System equipment and (b) if Customer [**] the System equipment after a [**], then the [**] of the System equipment shall be charged service fees under [**] with NxStage as if the [**].

Equipment Service and Maintenance Costs -- Purchased Equipment+
[**]			[**]
[**]	[**]	[**]	[**]	[**]	[**]
[**]	[**]	[**]	[**]	[**]	[**]

⁺ For System equipment for which the applicable time period set forth in the table above has not yet lapsed, service is [**].

*This is intended to cover units [**] by NxStage customers acquired by Customer.

With respect to Service Fees owed during any month of the Term, NxStage will invoice Customer for such fees by no later than [**]. Each invoice shall identify the relevant equipment by PIN and the original serial number and current serial number associated with the PIN and shall be sent to the Authorized Customer Location that is currently in

possession of the equipment (based on the location that is listed in NxStage’s database). Customer is responsible for notifying NxStage if Customer transfers equipment from one Authorized Customer Location to another Authorized Customer Location. Notwithstanding the foregoing, Customer agrees and acknowledges that NxStage has until [**] to invoice for Service Fees owed for [**].

Starting [**] and by the end of every [**] thereafter during the Term, NxStage shall provide to Customer a written report of all NxStage equipment ever purchased by Customer (including NxStage equipment purchased through Customer’s acquisitions of existing NxStage programs) with the following detail: (a) PIN, (b) original PIN issue date, (c) the Authorized Customer Location to which the PIN was originally shipped,(d) the original serial number associated with the PIN, (e) the current location of the PIN (based on the location that is listed in NxStage’s database), (f) the current serial number associated with the PIN, (g) the date the PIN was purchased, and (h) the date on which NxStage will begin [**] on the PIN.

Notwithstanding any other provision contained in the Agreement and for the sake of clarity, the foregoing pricing for Service Fees shall apply only during the Term and shall not survive termination of the Agreement. However, upon termination, NxStage shall [**]. After termination, for any System equipment purchased prior to the Effective Date or during the Contract Term for which the applicable time period set forth in the table above has not yet lapsed, for the remaining period of time, NxStage shall [**], in accordance with Section 25 of Schedule A. Except as stated in the foregoing sentence, after termination, NxStage may at any time separately [**]. After termination, for any System equipment purchased prior to the Effective Date or during the Contract Term for which the applicable time period set forth in the table above has lapsed, for [**] years from the original purchase date of such System equipment, the fees for service charged by NxStage to Customer shall not be more than [**].

Additional service charges for Systems shall also apply in the event (i) the System has been repaired or serviced by persons other than NxStage personnel or its authorized representatives, (ii) the replacement or repair is required due to the misuse or abuse of the System, as reasonably determined by NxStage, (iii) the System is used with non-NxStage disposable products, (iv) the replacement or repair is required for reasons other than defects in materials and workmanship or, in the case of equipment, normal wear and tear, as determined by NxStage, or (v) the System is not used in accordance with its instructions for use, as determined by NxStage. Such additional fees shall be charged consistent with NxStage’s then-current Fee for Service Program, the details of which shall be provided to Customer upon request.

To obtain service, Customer must contact NxStage Technical Support. Prior authorization from NxStage must be obtained before any Product is returned for service. Systems and other equipment supplied hereunder requiring service must be cleaned, according to the directions on the labeling. If Products are not cleaned, as instructed, NxStage shall charge Customer a minimum $[**] cleaning fee for each piece of equipment. NxStage will arrange for the shipment of all Products to be returned for service. NxStage will not be responsible for servicing Products that have not been shipped according to this procedure. NxStage shall use commercially reasonable efforts to repair or replace serviced Product within approximately [**] hours of giving authorization for service. Replaced Products shall be in good working order; they may or may not be new, and they may or may not be the same products originally shipped to Customer hereunder. For this purpose, good working order shall mean that the Product shall perform in accordance with its specifications and manuals, and be in physical condition and functionality equal to or better than that of the Product being replaced. In addition, NxStage shall use all commercially reasonable efforts to ensure that replacement Systems provided to Customer in connection with a service swap shall have an average days in service approximately equal to or less than the estimated days in service of the System returned by Customer in connection with a service swap hereunder.

Periodically, NxStage may elect to diagnose equipment servicing issues remotely, through data analysis or phone interviews. If equipment is returned at the insistence of Customer, or its patients, contrary to the recommendation of NxStage, and it is subsequently determined in the reasonable discretion of NxStage that such equipment was in good working order, Customer shall reimburse NxStage for the related costs of such return. NxStage shall use reasonable efforts to notify a designated Customer representative before accepting the return of equipment under such circumstances.

Recalls

In the event that any governmental agency or authority requests a recall, a field corrective action, product withdrawal or takes similar action in connection with any Product (each a "Product Recall"), or in the event NxStage determines an event, incident or circumstance has occurred that results in the need for a Product Recall, NxStage shall promptly notify Customer within [**] of such governmental agency or authority request or action or of NxStage's decision to voluntarily institute a Product Recall. In the event of a Product Recall of any Product, NxStage shall (a) reimburse Customer for reasonable handling expenses incurred in returning units of the Product to NxStage or otherwise implementing the Product Recall; and (b) use all commercially reasonable efforts to promptly repair or replace the recalled Product with another NxStage product performing the same function in good working order. If a Product Recall materially and negatively impacts Customer's ability to perform under this Agreement, NxStage shall allocate replacement Product to Customer consistent with Customer's then-current share of NxStage's Product in the field.

C) Customer agrees that Products provided by NxStage pursuant to Section 1(A) above shall be used solely for purposes of the Program.

D) PureFlow SL Supplies and PureFlow Express (Bags) Supplies (as defined in the chart below) will be made available by NxStage for Customer’s Program patients.

F) For each Program patient (i) that Customer trains on its in-center dialysis floor, (ii) whose physician prescribes more frequent therapy with the NxStage System One after completing the Program, and (iii) who remains on more frequent therapy with the NxStage System One for an additional [**] from the end of the Program, NxStage will [**] within [**] days after Customer notifies NxStage that the criteria above has been met. For the sake of clarity, NxStage will not [**] with respect to a particular patient if Customer used any unused Product available at its center for the Program for such patient to minimize any Product deliveries required from NxStage during the Program.

2. TERM OF PROGRAM

The Program will be available to Customer during the term of the Agreement; provided that the parties agree that each individual patient may only participate in the Program for up to five (5) days and no longer.
