NOW THEREFORE, for and in consideration of the mutual
covenants and agreements set forth hereinafter and for other good and valuable consideration, the receipt and sufficiency of which is hereby acknowledged, the parties hereto do hereby agree as follows:

ARTICLE I

SCOPE OF AGREEMENT AND WORK/CHANGE ORDERS



|1.1 | This Agreement allows the Parties to contract for multiple projects through the issuance of individual Work Orders (as discussed below) without having to re-negotiate
the basic terms and conditions contained herein.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|1.2 | The specific duties and responsibilities for each project under this Agreement (each a Project) shall be separately negotiated and specified in writing on
terms, and in a format, mutually agreed upon and executed by the Parties (each such writing, a Work Order). Each work Order shall include (i) the scope and specification of the Project; (ii) deliverables and timelines;
(iii) any performance metrics; and (iv) a budget and payment schedule. Any material change in the details of a Work Order shall require a written amendment to the Work Order, mutually agreed upon and executed by the Parties (a Change
Order).
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|1.3 | Any and all Work Orders or Change Orders issued and executed pursuant to this Agreement will be made part hereof and incorporated herein by reference, and shall be
subject to the terms and conditions set forth in this Agreement. Any and all Work Orders or Change Orders shall also be subject to the terms and conditions set forth in the quality requirements agreement to be completed and executed by the parties
and attached hereto as Exhibit A (the Quality Agreement), unless otherwise expressly set forth In the Work Order or Change Order. The Parties shall use commercially reasonable efforts to finalize and execute the Quality Agreement within
thirty (30) days of the Effective Date. To the extent there is any conflict between the provisions of this Agreement, the Quality Agreement and a Work Order and/or Change Order, the terms and conditions of this Agreement shall govern.
|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



---

|1.4 | Services provided by AAI shall comply with all applicable Good Laboratory Practices, current Good Manufacturing Practices, Good Clinical Practices, and all other United
States governmental and regulatory standards, specifications and guidelines, as specified in the Quality Agreement.
|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|1.5 | The Parties understand that AAI shall use commercially reasonable efforts to initiate, conduct and complete the Services as set forth in a Work Order in a timely
fashion. The Client understands and agrees that completing the Services as set forth in a Work Order assumes the full cooperation of the Client as well as other third parties.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

ARTICLE II

PROJECT IMPLEMENTATION



|2.1 | Prior to AAIs commencement of Services hereunder, the Parties shall execute one or more Work Orders. The Clients execution of a Work Order will be deemed
its authorization for AAI to proceed under the terms and conditions of this Agreement and the Quality Agreement, if applicable.
|--- | -------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.2 | AAI shall utilize commercially reasonable efforts to provide the Services as agreed in the Work Order and, if necessary, any associated Change Order.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------



|2.3 | The Parties recognize that in certain instances, the Client may wish AAI to commence Services prior to the formal execution of a Work Order authorizing such Services.
In such circumstances, the Client may authorize AAI in writing (hereinafter, Letter of Authorization) to commence specified Services pending execution of the relevant Work Order. The Letter of Authorization shall specify the Services to
be performed and a dollar limitation for the performance of such Services.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.4 | AAI shall use commercially reasonable efforts to anticipate the scope of activities necessary to complete Services established by a Work Order. However, Work Orders
constitute both Parties informed estimate of those Services necessary to satisfactorily complete a Project and are based upon the Parties current knowledge of the factual situation as well as the current regulatory environment.
Therefore, the scope of proposed Services may require modification of the Work Order during the course of performance. In the event additional or different Services are required, the Clients authorized representative, as set forth in Article
VIII, may in writing authorize AAI to perform additional or different Services. AAI shall promptly acknowledge the Clients written authorization by issuing a Change Order for such additional or different Services.
|--- | ------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|2.5 | AAI will use commercially reasonable efforts to complete the agreed upon Project within the limits set forth in the executed Work Order or Change Order. However, the
Parties recognize that the Services to be provided hereunder are not subject to precise advance determination. In the event unforeseen difficulties arise, AAI shall inform the Client, outlining the basis for such conclusion. In such event, the
Parties agree to enter into good faith negotiations regarding the terms of the Work Order applicable to the Project.
|--- | ----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|3.4 | AAI shall not engage any third party for any of the Services as set forth in the Work Order or Change Order without the prior written consent of the Client.

|3.6 | Unless otherwise agreed by the Parties in writing, AAI shall invoice the Client on a calendar month basis for Services rendered as set forth in the Work Order. Invoices
are due and payable net thirty (30) days after Clients receipt of invoice. All payments to AAI shall be made in U.S. dollars. Invoice balances not remitted within thirty (30) days of receipt of invoice shall be subject to a one and
one-half percent (1.5%) per month interest charge. Should any part of the invoice be in dispute, the Client shall pay any undisputed amount according to the terms and conditions described herein while said dispute is being resolved.

|--- | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.2 | Any inventions (whether or not patentable), processes, techniques, improvements, discoveries, trade secrets, know-how and developments discovered and reduced to
practice by AAI solely or jointly for the purpose of performing the Services or other work performed under a Project (collectively, Project IP) are hereby assigned to Client (including any patent and all other intellectual property rights
therein), and shall be deemed the Confidential Information of Client for purposes of Article V below (Project IP). AAI will, at the expense and the written request of the Client, do all reasonable acts and things and execute all

|--- | --------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.3 | With respect to Project IP, AAI will not, to its actual knowledge, incorporate or use therein any invention, discovery, process, technology or

the terms of an appropriate license agreement for such AAI Proprietary Technology, with such license agreement memorialized in a separate writing.
| | ---------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------



|4.4 | The Client acknowledges that AAI is in the business of providing Services for a variety of organizations other than the Client. Accordingly, nothing in this Agreement
shall preclude or limit AAI from providing Services or developing materials for itself or other clients, or from utilizing the general knowledge gained during the course of its performance hereunder to perform similar Services for other clients,
provided that such provision of Services or development of materials do not constitute a breach of confidentiality under Article V herein.
|--- | -----------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------------

ARTICLE V
