1. Company Summary

** **

Sterling Pharma Solutions has over 50 years’ experience of supporting our customers globally with projects from pre-clinical to commercial manufacture. Each year we develop, scale up and manufacture to cGMP over 150 stages of chemistry. In the last four years we have supported our customers through clinical supply and launch with 16 new chemical entities.

Differentiated by the three core characteristics of service, passion, and science, we are more than a traditional CDMO. We are a PDMO®, or partnership development and manufacturing organization. That means we are uniquely responsive to your needs, committed to your product, and capable of adding a deep level of scientific value.

Whilst science can be complex, we believe partnerships should be simple.

4. Manufacturing plan

** **

Sterling strives for right-first-time execution with a focus on safety and quality. The technical transfer from development to manufacture is performed through a series of governance processes and continued technical, EHS and quality management before, during and after manufacturing. The estimated production and material resources are based upon the learnings from laboratory familiarization work, including the activities listed below.

The following manufacturing support activities are included:

*Documentation: *Generation of the necessary master production and testing records will be performed. These will be provided for review and/or approval of the AIM Immunotech and developed in conjunction with AIM Immunotech. Timelines are dependent upon timely review and approval of these documents in support of manufacturing.
*Technical management: *Technical support during the campaign will be provided for the standard transfer and management of the production activities. This will include support from the technical staff (chemistry, analytical and engineering teams) to perform process and method training to all involved operations staff.
Stewardship: Sterling’s EHS, technical services, and quality department personnel will ensure compliance with global regulatory frameworks with respect to manufacturing operations and workplace safety. This includes, but is not limited to, the review of toxicological information, occupational health review of processes and ingredients, health-based exposure limit (“HBEL”) determinations, maximum carry over calculations for cross-contamination and a site risk assessment.
Cleaning: Development and validation of appropriate methods for the cleaning and verification of the equipment from production residues will be performed in support of this process. Additionally, all cleaning of the equipment is included in the standard manufacturing support package. Cleaning process validation is not included in the scope of this proposal. In support of this, a material questionnaire may be provided for a cleaning limit assessment.

Pricing and invoicing

** **

Sterling has made various estimates and assumptions in preparing this Proposal, including the value and volume of materials to be used and the amount of time above activities will utilise its facilities and personnel. Based on such estimates and assumptions, the Pricing Summary below provides the indicative price to provide the development, testing, and manufacturing activities by Sterling with supporting materials, supplies, and waste included unless explicitly listed otherwise. Sterling will endeavor to ensure the price quoted below is the maximum price and will regularly review and monitor any potential for increased costs, however, some variables are not within Sterling’s control and therefore if the estimates and assumptions can be demonstrated to be inaccurate, Sterling reserves the right to update the Pricing Summary, discuss with AIM Immunotech and invoice AIM Immunotech accordingly. Further if additional or out of scope activities and/or materials are required due to unforeseen outcomes or at the request of AIM Immunotech, Sterling will discuss with AIM Immunotech and provide a change order to support that work or activity.

Any third-party services and shipping handled by Sterling not explicitly listed below will be passed through at cost plus a handling fee.

6 Project Management

** **

Sterling will appoint a dedicated project manager to manage the project through all project stages. Standardized tools, techniques, detailed processes and procedures will be used to track, monitor, and communicate project progress throughout the lifecycle of the contract.

6.1 Communication management plan

Upon initiation, a detailed communication management plan will be created to support the project. This is expected to include, but is not limited to the following:

1. Regularly scheduled team teleconferences
2. Meeting minutes
3. Weekly written updates
4. Development/campaign final report
5. Team and escalation communication matrix

These processes will support, but not replace, formal communication outlined in the quality agreement.

This communications management plan sets the communications framework for this project. It will serve as a guide for communications throughout the life of the project and will be updated as communication requirements change. This plan identifies and defines the roles of the project team members as they pertain to communications. It also includes a communications matrix which maps the communication requirements of this project, and communication conduct for meetings and other forms of communication.

The assigned project manager will take the lead role in ensuring effective communications on this project. The communications matrix will be used as the guide for what information to communicate, who is to do the communicating, when to communicate it, and to whom to communicate.

6.2 Schedule

Based on the information provided by Client, assumptions made by Sterling, and the consultation of subject matter experts, a tentative schedule has been prepared to highlight significant milestones surrounding the proposal. Post-acceptance of this proposal, the assumptions will be reviewed and the schedule will be updated to reflect current timing and milestones accordingly. Any delay to the items indicated in the table below will have a direct impact to the overall timeline and delivery of the bulk API.

CONFIDENTIALPage 16 of 20

**6.3 **High level initial assumptions/tentative schedule:

The Gantt chart provided in this proposal is based off of assumptions (development time, cycle time, yields, etc.) derived from the information provided by the client and assumes approval by Client within 30 days. Should capacity or availability of resources change due to signature of other projects prior to execution of this proposal Sterling will notify Client and discuss any potential impacts.
