PRICE SCHEDULE

Pricing for Units of the Product


Order	Base Price per Unit ($US)
[***]	$	[***	]
[***]	$	[***	]

*	Base Prices are controlled by placement of the Firm Order, not the delivery date.

[***]

StemCell reserves the right to adjust the Base Price per Unit in accordance with the provisions of Section 7.1.2 of the Agreement.

Unit Discounts:

A Unit Discount means a percentage reduction in the Base Price per Unit from that recited in the table above. A Unit Discount will be applied to all Units based on the number of Units purchased by Oxford in the previous 12 month period prior to placing the Firm Order (“Rolling Year”), based on the following chart:


Number of Units purchased in Unit Year	Unit Discount from Base Price Per Unit
[***]		[***	]%
[***]		[***	]%
[***]		[***	]%

Notwithstanding the foregoing for purposes of calculating the applicable Unit Discount in the first fourteen month period immediately following the receipt of US FDA approval (the “First Period”), the measuring Unit Year shall be the next twelve months after the placement of the Firm Order and the number of Units purchased shall be deemed to be sum of the number of Units subject to the Firm Order and the number of Units included in the non-binding forecast for the subsequent nine (9) month non-binding forecast period. However, the First Period Unit Discount shall be subject to reconciliation as set forth below.

By way of example for the First Period:

•

if the number of Units covered by the Firm Order plus those included in the nine (9) month forecast is less than or equal to [***] units, the Unit Discount applied to the ordered Units will be [***]%;

-4-

•

if the number of Units covered by the Firm Order plus those included in the nine (9) month forecast is greater than [***] and less than or equal to [***] Units, the Unit Discount applied to the ordered Units will be [***]%;

•

if the number of Units covered by the Firm Order plus those included in the nine (9) month forecast is greater than [***] units, the Unit Discount applied to the ordered Units will be [***]%.

The number of Units purchased will be, both for the First Period reconciliation and in subsequent rolling twelve month periods, the number of Units shipped by StemCell during the measurement period.

Reconciliation of Applicable Unit Discounts:

Within sixty (60) days of the end of the First Period, the Parties shall determine the number of Units shipped by StemCell during the last twelve months of such First Period. In the event that the number of Units purchased results in a different Unit Discount than has been applied during the First Period, the Parties will retroactively adjust the pricing and any additional payment due to StemCell shall be paid within thirty (30) days thereafter. If Oxford has overpaid based on the reconciled Unit Discount applicable to the First Period purchases, StemCell shall, at Oxford’s option, issue a credit to Oxford to apply to any future purchase of Oxford’s choice or refund the overpayment within thirty (30) days.

By way of example:

•

if Oxford purchased [***] Units during the last twelve months of the First Period and the Unit Discount that had been applied to all purchases during the First Period was [***]%, Oxford will be entitled to an additional [***]% discount on all Units purchased in the First Period;

•

if Oxford purchased [***] Units during the last twelve months of the First Period but had been accorded a Unit Discount during the First Period of more than [***]%, Oxford must pay StemCell the difference between the Unit Discount rate that was applied to its purchases during the First Period and the [***]% that is applicable.

After the First Period, the applicable Unit Discount will be calculated based on the number of Units purchased by Oxford in the applicable Rolling Year.

The minimum order size is [***] ([***]) Units.
