Estimated Timeline and Pricing

Projected Timeline and Risk Assumptions

Figure 1. Estimated Project Timeline

[***]

Timeline/Risk Assumptions:

The Projected Timeline shown above (the “Projected Timeline”) is an estimate. The Projected Timeline provides the estimated timing for the critical path activities included in this SOW. Transfer and scale-up to GMP manufacturing of the legacy process is shown in solid blue. DP manufacturing is shown in green. Process Development of a modernized process is shown in light blue.

The Projected Timeline assumes unconstrained capacity from a resource and asset perspective and does not depict optional activities. The Projected Timeline additionally assumes that material lead times will not cause delays. The Projected Timeline is further subject to change based on start date, availability, scope amendments, and individual Client requests. Upon verbal award, Scorpius will assess the Project’s scope against current capacity based on an expected start date to confirm availability to support. The following Project-specific assumptions were used to develop the timeline above:

Program timing spans initiation of technology transfer to CGMP BDS lot release (using the transferred process) and is expected to require approximately 8 months to complete. Process modernization extends the timeline to approximately 12 months.

Technology transfer documentation and materials will be provided at the outset of the program. Delays in document/material sharing may have a significant impact on the overall timeline for technology transfer.

Analytical method implementation is expected to use representative reference material provided by Tivic. If representative material is not available, process transfer batch material will be used, and several weeks will be added to the critical path.

Formulation development is not expected to be required. If required, timelines may be

extended.

Lead time for DP manufacturing is currently assumed to be three (3) months, with two (2) to six (6) months on average.

No equipment will need to be procured to support Tivic’s program.

Cost Estimate

Pricing Assumptions:

Scorpius reserves the right to revise quoted costs to account for changes in initial scope Tivic, will be notify of any revisions in the protocols and modifications of testing plans, final review of test methods, requests for additional data or reports, undocumented requirements, or any unforeseen difficulty in executing the Project. The additional work may be added upon written agreement and will be documented in a Change Order.

Service Fees do not include pass-through costs such as raw materials, consumables, reagents, shipping, and subcontracted services. Scorpius will procure and manage these items/services on behalf of Client at Client’s cost plus a 15% administrative fee. Client direct invoicing is subject to confidential pricing terms negotiated between the 3rd-party vendor and Scorpius.

Delivery of final product is ExWorks (Inco terms 2020) as outlined in the T&Cs and will be subject to the mutually approved Master Service Agreement.

Assumptions:

[***]

Activities:

Scorpius will execute Tivic’s transferred fermentation process using the ambr®250 system (up to 4 vessels). Each vessel will be harvested by centrifugation and individually analyzed by SDS-PAGE. Material from each vessel will be purified through the initial capture step for analysis. If full purification is required for each vessel, the additional processing will be covered via a Change Order.

Scorpius will then execute Tivic’s transferred process at the 50 L scale (25 L working volume) using Tivic’s MCB to generate material to demonstrate process performance and support development activities for facility fit.

o Harvest material (i.e., cell paste) will be frozen and used for initiation of downstream process transfer and appropriate development activities. Generated materials (in- process and final DS) feeding analytical method implementation/development will be suitably purified using the transferred downstream process. A portion of the 50 L material will also be forward processed in a representative-scale downstream process.

Deliverables:

1. Data summary

Legacy Process Establishment (Stage 2)

Section 4: Analytical Method Implementation

Objective: Implement Client’s product-specific release and stability-indicating methods at Scorpius.

Assumptions:

The preliminary BDS formulation will be identified prior to completion of analytical method implementation/development. Changes in formulation may impact method performance and necessitate optimization for additional costs to be covered via Change Order.

When applicable, development work will be initiated using in-house platform methods and/or commercial kits and will be focused on examination of performance characteristics pertinent to the Quality Attribute (QA) and clinical Phase to ensure the procedures are fit-for-purpose.

If a method for implementation or a platform-based method is deemed unsuitable for qualification/validation and further work is required, a Change Order may be required to capture the additional scope and costs for product-specific development.

If necessary, product-specific development will occur if platform- or commercial-kit- based method is not suitable.

Tivic shall own all Deliverables provided by Scorpius to Tivic.

Activities:

Present development plan using information provided by Tivic/ 3rd-party CLD vendor and

Scorpius’ previous experience.

Section 5: Non-CGMP Demonstration Batch

Objective: Manufacture a demonstration batch at the 50 L scale in the PD lab to de-risk scale-up and ensure readiness for CGMP manufacturing.

Assumptions:

The non-CGMP demonstration batch will utilize the MCB and locked manufacturing process.

Material from the demonstration batch will be used for analytical method qualification. Material may also be placed on stability upon request, via Change Order.

Tivic will provide process intermediate hold-time stability data to Scorpius. If data is not available, a hold-time stability study may be added for additional costs to be covered via Change Order.

Tivic shall own all Deliverables provided by Scorpius to Tivic.

Activities:

Scorpius may refine Process Instructions, including sampling plan, for execution of the process at the demonstration scale, incorporating any recommendations agreed upon between Scorpius and Client from previous batches.

Scorpius will thaw cells from the appropriate cell bank and scale up to the production volume using the transferred fermentation process. Material will be harvested and frozen as intermediate product. A predetermined amount (TBD) will be thawed and forward processed through extraction and purification using the transferred downstream process according to the approved Process Instructions. Scorpius will scale the downstream process such that cycling remains consistent with the expected CGMP scale. The purification steps will be followed by formulation and bulk fill.

o Harvest, in-process, and release testing plans will be developed by Scorpius and Tivic. Testing of unprocessed bulk harvest (UBH) material will be performed by a 3rd-party CTO according to Table 6, while Scorpius or 3rd-party vendor will perform the in- process and release testing proposed in Table 9. Current costs assume that in-process testing will only be performed on the last cycle of each step, where applicable. Material will not be formally released by Scorpius QA.

Section 6: Analytical Method Qualification

Objective: Demonstrate that analytical procedures for release and stability-indicating assays are suitable for their intended purpose and Phase-appropriate.

Assumptions:

A Quality Agreement and Master Services Agreement must be executed before Scorpius provides draft qualification protocols to the Client.

Material for analytical method qualification will be derived from the non-CGMP demonstration batch.

Analytical method qualification will demonstrate analytical procedures are fit-for- purpose, but formal acceptance criteria will not be defined until test methods are fully validated.

Analytical methods will not be validated until the final formulation has been identified.

Changes to the final product, process, or analytical procedure itself may require partial or full requalification to ensure that the analytical procedure remains fit-for-purpose. If required, the scope of requalification will depend on the nature of change, and the additional costs will be captured through a Change Order.

Any outsourced assays will be contracted to a qualified CTO. All costs will be passed through to Client with applicable administrative fee.

Tivic shall own all Deliverables provided by Scorpius to Tivic.

Activities:

Scorpius will perform the services depicted in Table 7 following the general guidance of ICH Q2 to ensure analytical procedures are suitable for their intended purpose.

Non-compendial release and stability-indicating assays will be qualified within the CGMP lab. Performance characteristics for analytical method qualification will depend on the type of analytical procedure but typically include specificity/selectivity, linearity, range, accuracy, precision, and detection or quantitation limit, as applicable.

Verification will be performed for compendial methods to demonstrate that the test performs according to specifications when applied to a specific product.

Section 7: 50 L CGMP Manufacturing

Objective: Manufacture and release CGMP compliant BDS.

Assumptions:

A Quality Agreement and Master Services Agreement must be executed prior to initiation of CGMP manufacturing activities.

The CGMP batch will utilize Tivic’s fully released MCB.

Chromatography steps will be completed with no more than three (3) cycles each using the transferred process.

o If additional cycles are required and downstream purification takes longer than anticipated, per-batch costs may increase and be captured under a Change Order.

Scorpius standardizes CGMP manufacturing batch preparation activities by first performing an at-scale, non-CGMP engineering batch in the CGMP suite as a risk mitigation prior to initiating a CGMP manufacturing batch. Client accepts all risks associated with bypassing an engineering batch, provided Client explicitly consented to bypassing such engineering batch beforehand in writing.

Tivic shall own all Deliverables provided by Scorpius to Tivic.

Activities:

Scorpius will procure and release all necessary raw materials and consumables in a manner suitable for use in clinical manufacturing and consistent with the Quality Agreement.

Scorpius will refine Batch Records for execution at the final CGMP scale based on the executed non-CGMP demonstration batch.

Client will have five a maximum of five (5) business days to provide a single round of review for each Batch Record per the Quality Agreement.

Scorpius will execute Client’s manufacturing process according to Client-approved Batch Records using the MCB. If necessary, Scorpius will scale the downstream process such that cycling remains consistent with the demonstration batch. BDS will be bulk filled into bottles or bags, as mutually agreed upon between Scorpius and Tivic.

Harvest, in-process, and release testing plans will be executed according to a client- approved Sampling Plan. Testing of UBH material will be performed by a 3rd-party CTO according to Table 6, while in-process and release testing will be performed by Scorpius or a 3rd-party vendor as proposed in Table 9. Current costs assume that in- process testing will only be performed on the last cycle of each step, where applicable.

Final BDS will be formally released by Scorpius QA.
