2.4 Business Development. Biose remains free to conduct any business development activities, during the term of this Agreement for the manufacture and supply of non-genetically modified single Strain Product intended for oral delivery, as long as performance of such manufacturing and/or supply activities begins after the termination of this Agreement.

ARTICLE 3. COMMITTED RUN RESOURCES; RUNS

3.1 Reservation. During the Term, Biose will reserve personnel with appropriate expertise, facilities and equipment sufficient and in an fully operational state to allow it to conduct Runs for Evelo to manufacture Product(s) as set forth on Exhibit A (“Committed Run Resources”) meeting the specifications.

The Parties acknowledge that Biose can conduct Runs for Evelo on no more than [***] Strains per Agreement Year. For the sake of clarity, new Strain refers to an Evelo Strain that was never produced by Biose at its GMP facility.

3.2 Priority. In allocating access to its [***] fermenter, Biose shall make its best efforts to treat Evelo with higher or equal priority in relation to other Biose’s customers so long as Evelo provides Biose with a minimum of [***] advance notice for Committed Run Resources.

3.3 Run Fees; Payment Commitment; Released Resources.

(a) For a Run, Evelo will pay to Biose amounts as follows: (i) an Engineering Run fee will be [***]; and (ii) a GMP Run fee will be [***]; provided, however, if Evelo elects to forego an Engineering Run for a given Strain before having Biose perform a GMP Run with such Strain, Evelo will pay to Biose [***] for such GMP Run (i.e., an additional [***] more than the normal [***] GMP Run fee). The Run fees above are fixed for the term of this Agreement, and do not include [***].

(b) During the Term, Evelo shall have no obligation to utilize any of the Committed Run Resources. If the Committed Run Resources are available for use by Evelo in accordance with the schedule in Exhibit A, but Evelo elects to not conduct any Run(s) utilizing all or part of the applicable Committed Run Resources in an Agreement Year, then Evelo shall, notify Biose, as soon as practicable but in case at least [***] prior to the start date of the subject Run(s), of Evelo’s election, that it either (i) authorizes Biose to seek an alternative customer for use of such Committed Run Resources, or (ii) does not authorize Biose to seek an alternative customer for use of the applicable Committed Run Resources, in which case, Evelo will be obligated to pay Biose for such unused Committed Run Resources, subject to the terms Section 7.6(b) and (c), if applicable.

Confidential Portions of this Exhibit marked as [***] have been omitted pursuant to a request for confidential treatment and have been filed separately with the Securities and Exchange Commission.

(c) If Evelo authorizes Biose to seek an alternative customer for use of such Committed Run Resources (“Released Resources”), then Biose shall have the option to seek an alternative customer for the use of such Released Resources. For the sake of clarity, an alternative customer is a customer that was not scheduled in Biose’s manufacturing planning at the time Evelo notifies Biose that it may seek an alternative user of the applicable Released Resources.

(i) If Biose utilizes such Released Resources for a third party, then Biose (x) may retain any amount paid by such third party for such manufacturing, and (y) will reimburse Evelo for any Run fees previously paid by Evelo for the applicable Released Resources.

(ii) If Biose itself uses the Released Resources for which Evelo authorized Biose to seek an alternative customer to manufacture a Run that was not already scheduled in Biose’s manufacturing planning, then Biose will reimburse Evelo for any portion of the Run fees previously paid by Evelo for the applicable Released Resources.

(iii) If Biose is unable to locate another alternative customer to use such Released Resources, and Biose does not use such Released Resources for manufacturing purposes, then Evelo shall be obligated to pay Biose for the applicable unused Released Resources at the rate of [***] (taking into account any advance payments made by Evelo for such Released Resources).

(d) Subject to Section 3.3(c) above, any amounts due to Biose for Committed Run Resources that are unused by Evelo in a particular Calendar Quarter shall be paid by Evelo to Biose on the same payment terms as if this Committed Run Resources had been used by Evelo. Any amounts due to Biose for Committed Run Resources that are unused by Evelo in a particular Calendar Quarter shall be paid by Evelo to Biose with [***] of the end of the applicable Calendar Quarter after a financial reconcilation of all (i) amounts paid by Evelo for such Committed Run Resources for such Calendar Quarter, (ii) additional payments due to Biose for use or non-use of such Committed Run Resources for such Calendar Quarter, and (iii) reimbursements due to Evelo from Biose with respect to Released Resources.

(e) Notwithstanding the other terms of this Section 3.3, if any Committed Run Resources cannot be used by Evelo due to matters outside of Evelo’s control (e.g., relating to contamination of Committed Run Resources or other Biose operational issues or decisions), then Evelo shall not be obligated to pay Biose for any Committed Run Resources that cannot be used for Evelo due to such unavailability. For clarity, if any Committed Run Resources are available for use by Evelo, and Evelo elects not to use such Committed Run Resources for reasons unrelated to Biose’s abililty to perform (e.g., delays in clinical trial progress), then the terms of this Section 3.3(e) shall not apply.

3.4 Pricing. Evelo shall be entitled to credit 100% of the fees paid by Evelo pursuant to Section 3.3 when paid upfront or as a prepayment for the applicable Run against any corresponding payments due for such Run. For clarity, the Run fees include the manufacture of Product by Biose but not any raw materials.
