“Campaign” means a series of Batches of the Product that are produced in sequence at the Facility followed by validated cleaning of such equipment and purification suite, and for the purposes of counting the number of Product batches in a Campaign in a given period, the start date of such Campaign shall be the determining factor. A Campaign will be deemed to end upon the completion of such cleaning.

“Firm Period” means (a) the first [***] of the [***]Year Forecast accepted by SBL, and the first [***] of the Quarterly Forecast accepted by SBL, during which period the Forecast shall be [***] firm and binding on both Parties and (b) the [***] of the [***]Year Forecast accepted by SBL, during which period the Forecast shall be [***] as described in Section 5(d)(i)(4) below.

“[***]Year Forecast” has the meaning set forth in Section 5(d)(i)(1).

“New Batch” means any Batch of Commercial Product that is requested to be delivered in the Quarter newly entering the Quarterly Forecast (i.e., the Quarter that was not covered by the prior Quarterly Forecast).

“Quarterly Forecast” means Client’s projection of its requirement for delivery of Batches of Commercial Product in each Quarter over a period of [***] quarters, on a rolling basis. For

[***] Certain information in this document has been excluded pursuant to Regulation S-K, Item 601(b)(10)(iv). Such excluded information is not material and would likely cause competitive harm to the registrant if publicly disclosed.

Forecasts / Purchase Orders

[***] Year Forecast

By [***] of each Year of the PSA term, Client shall provide to SBL a rolling Annual Forecast for the next [***] Years (the “[***] Year Forecast”). For the sake of clarity, (A) Client provided to SBL the first [***] Year Forecast on [***] and (B) Client does not have to specify any quantities in the [***] Year Forecast for time periods beyond December 31, 2031 (i.e., the [***] Year Forecast may not always cover a full [***] year period).

Within [***] days of receipt of any [***] Year Forecast, SBL shall provide a written acceptance or comments. Upon SBL’s written acceptance, the applicable Firm Period shall be firm and binding as to the total number of Batches of Commercial Product that are to be delivered in each Year of the Firm Period.

If SBL provides comments on the [***] Year Forecast (rather than acceptance), then the Parties shall further discuss in good faith to agree on the [***] Year Forecast that can be accommodated based on SBL’s available capacity.

The [***] Year of each [***] Year Forecast shall be partially binding on Client as follows: when the [***] Year of any [***] Year Forecast becomes the [***] Year of the next [***] Year Forecast, such [***] Year must forecast between [***] of the [***] Year of the previous [***] Year Forecast. For clarity, both SBL and Client agree that the [***] Year Forecasts will include quantities measured only in [***]. By way of example only, [***].

Each [***] Year Forecast issued by Client shall be consistent with the Product Purchase Commitment and the previously issued [***] Year Forecast in terms of Batches of Commercial Product forecasted for each Year falling in the Firm Period of the [***] Year Forecast.

Notwithstanding anything to the contrary, upon Client’s request, SBL shall use Commercially Reasonable Efforts to Manufacture Batches in excess of the number of Batches set forth in any Firm Period, subject to SBL’s existing commitments.

ii.

Quarterly Forecast

At least [***] days prior to start of each Quarter of the PSA term during which SBL is Manufacturing Commercial Product, Client shall provide to SBL a rolling Quarterly Forecast that begins with such Quarter.

The Quarterly Forecast shall set forth the Batches of Commercial Product that are requested by Client to be delivered in each Quarter of the Quarterly Forecast. Quarterly Forecasts shall be consistent with the then-current [***] Year Forecast when requesting Batches to be delivered in a Quarter falling in the Firm Period of any [***] Year Forecast. If there is a conflict between

any Quarterly Forecast and any [***] Year Forecast regarding a binding amount, the [***] Year Forecast shall supersede unless agreed to in writing by SBL.

xxx.Xxxxxxxx Schedule and Purchase Orders

Each time Client submits a Quarterly Forecast to SBL pursuant to Section 5(d)(ii), SBL and Client shall discuss in good faith the Manufacturing schedule for each New Batch. The Parties shall discuss in good faith for up to [***] days and shall agree upon a Manufacturing schedule for the New Batches covered by the Quarterly Forecast, upon which Client shall issue a binding Purchase Order for each New Batch, consistent with the Parties’ agreement and the Quarterly Forecast. The Purchase Order shall detail the New Batches requested, and estimated delivery date(s) for such New Batches, which delivery date shall be finalized upon SBL’s release of the New Batches pursuant to Section 4.12 of the MSA.

When deciding a Manufacturing schedule for the New Batches, the Parties agree that (a) all Manufacturing shall be on a [***] Campaign per Year basis, and (b) if there is more than [***] Campaign per Year scheduled as a result of a Quarterly Forecast, then Client will be subject to a product changeover fee of $[***] per additional Campaign. If the Parties agree to add additional Batches to a Campaign that was already scheduled pursuant to a previous Quarterly Forecast, Client shall re-issue the previously issued Purchase Orders to align with such new agreement, but will not be subject to a product changeover fee. SBL will use Commercially Reasonable Efforts to accommodate additional Batches into a Campaign that was already scheduled pursuant to a previous Quarterly Forecast. The Service Fee for any Batch in an additional Campaign in a single Year will be calculated based on the number of Batches in such additional Campaign.

The Parties agree and acknowledge that actual yields of Formulated Drug Substance per Batch may vary, even when Manufactured in accordance with the Manufacturing Process. For the sake of clarity, the Service Fee per Batch identified in Exhibit C will not vary based on the actual yield of Formulated Drug Substance produced in accordance with the Manufacturing Process.

Xxxxx in Use of Reserved Capacity.
