***** Certain information on this page has been omitted and filed separately with the Securities and

If Allergan increases the cost of the Product as the result of an ECR the cost of the Product will increase immediately. CZOS will invoice
Allergan for all costs associated with the implementation and/or validation of any requested ECR for said Products. This would include but is not limited to materials that may become scrapped and/or excess based upon the ECR. CZOS will notify

Section 5. Place of Manufacture; Right of Inspection



Section 5.2 Allergan Inspection is amended by deleting
the phrase twenty-four (24) hours advance notice in the first sentence and inserting forty-eight (48) hours advance notice in its place.



Section 6. Terms of Supply



Section 6.2 Forecast and Supply Amounts is amended in its entirety to read as follows:

Allergan shall, on a monthly basis, provide CZOS with a twelve (12) month, non-binding forecast of estimated Products needed by the tenth
(10th) working day of each month. CZOS shall use Allergans forecast to plan and build products to support the
forecast. Lead-time for Product(s) shall be no more than ***** (*****) calendar days form receipt of Allergans purchase order to shipment of product. However, it is understood that, in the case where the requested shipping date is sooner than
such period, CZOS shall make all reasonable efforts to comply with Allergans requested shipping dates. Should Allergans purchase orders exceed the appropriate forecast, CZOS shall make its best efforts to produce at least the incremental
increases as follows: (i) one hundred percent (100%) for more than 90 work days of lead time; (ii) twenty percent (20%) for lead times between 60 and 90 work days; (iii) ten percent (10%) for lead times between 30 and 60 work days; and (iv) zero
percent (0%) for lead times less than 30 work days. There shall be no minimum annual order quantities for the finished goods Product(s). Allergan and CZOS shall continually seek ways to reduce manufacturing lead times. All materials that have been
purchased on the behalf of Allergan that are considered End of Life (EOL) of obsolete will be fully covered by Allergan with a purchase order at the materials cost if not consumed by the end of the agreement. Obsolete inventory should be identified
at the time an ECR is created and approved.



Section 6.3 Purchase of Inventory is amended by adding the following after its last sentence:

It
shall be the responsibility of Allergan to purchase or buy in advance or at termination of the Agreement, any materials associated with End of Life (EOL), Excess and Obsolete related to sustaining the current Product, or contributed to ECR and/or
cost saving proposals so long as these materials were purchased or manufactured by CZOS in the mutually agreed quantities or to support the most current forecast as stated in Section 6.2. (See the items below.)
