Development Costs. (a) On a quarterly basis for each Research Program, Spyre will advance to Paragon any Development Costs contemplated in the Budget, including [***], and any [***] reasonably expected to be incurred by Paragon in the performance of the Research Program during the upcoming [***] (less any pre-payments for Third Party Costs from earlier [***] that Paragon reasonably anticipates will be carried over to such upcoming [***]) (the “Cost Advance”). Spyre will pay the Cost Advance within [***] days after receipt of Paragon’s invoice for such Development Costs. The Parties acknowledge that Paragon has incurred approximately $10,000,000 in Development Costs prior to the Effective Date, as a result of work performed by Paragon at risk on one or more Research Programs (the “Pre-Effective Date Development Costs”), which amount includes for Research Initiation Fees of $3,000,000 for a total of four Research Programs. Spyre shall reimburse Paragon for the Pre-Effective Date Development Costs no later than [***] days after the later of (i) the Effective Date and (ii) Spyre’s receipt of a written invoice that details the Pre-Effective Date Development Costs and includes reasonable documentation therefor. (b) Within [***] after the end of each Calendar Year, Paragon will calculate and provide to Spyre a written reconciliation of its actually-incurred Third Party Costs (incurred in a manner consistent with the Budget) for the prior Calendar Year (“Actual Annual Costs”) against that portion of the Cost Advance for such Third Party Costs for that Calendar Year, including reasonable documentation of such Actual Annual Costs. The form of such reconciliation shall be subject to JDC review and approval. If the amounts paid for anticipated Third Party Costs in the Cost Advance exceeds the Actual Annual Costs, then Paragon will credit such excess payment against Development Costs contemplated in the Budget and reasonably expected to be incurred by Paragon in the performance of the Research Program during any upcoming Calendar Year and Spyre will deduct such amount from its next quarterly Cost Advance. If the Cost Advance is less than the Actual Annual Costs, then Paragon will invoice Spyre for the difference and Spyre will pay such amount together with its next quarterly Cost Advance. If no further amounts will be owed to Paragon hereunder, ▇▇▇▇▇▇▇ will refund such amount. For clarity, the above reconciliation will not apply to Annual Development Fees.

Spyre will pay the Cost Advance within [***] days after receipt of Paragon’s invoice for such Development Costs. The Parties acknowledge that Paragon has incurred approximately $10,000,000 in Development Costs prior to the Effective Date, as a result of work performed by Paragon at risk on one or more Research Programs (Aradigm shall submit to Grifols an invoice for the “Pre-Development Costs that Aradigm reasonably expects to incur during the first calendar quarter after the Effective Date in accordance with the Development Costs”)Plan and the Budget. Thereafter, which amount includes for Research Initiation Fees of $3,000,000 for a total of four Research Programs. Spyre shall reimburse Paragon for the Pre-Effective Date Development Costs no later than [***] thirty (30) days prior to the start of each calendar quarter while Development of an Aradigm Product for the Initial Indication is ongoing, Aradigm shall submit to Grifols an invoice for the Development Costs that Aradigm reasonably expects to incur during such calendar quarter in accordance with the Development Plan and the Budget. Grifols shall pay each such invoice in Dollars, the initial invoice being payable no later than thirty (30) days following Grifols’ receipt of the invoice, and for each subsequent invoice that is properly invoiced no later than the first day of each such quarter, provided that the invoice is consistent with the Development Plan and Budget. Aradigm shall have no obligation to perform Development activities affected by Grifols’ withholding payment of Development Costs which were included in the Budget. Notwithstanding anything to the contrary in this Agreement, and without limiting Grifols rights at law or in equity, if Aradigm fails to perform any specific Development activity during a calendar quarter, Grifols shall have no obligation to pay Development Costs to Aradigm for future calendar quarters until, at the discretion of Grifols, (i) all amounts previously paid by Grifols for such Development activity not performed by Aradigm have been reimbursed by Aradigm or credited to Grifols, or (ii) such Development activity has been properly performed by Aradigm.

(b) Within [***] In the event that the actual Development Costs were less than the Development Costs invoiced by Aradigm for that calendar quarter, Aradigm shall include a credit on the next quarterly invoice for such over-payment by Grifols (or, if the Development of an Aradigm Product for the Initial Indication has been completed, refund such over-payment to Grifols within thirty (30) days). In the event that the actual Development Costs exceed the Development Costs invoiced by Aradigm for that calendar quarter, Aradigm shall include such excess Development Costs on the next quarterly invoice. Notwithstanding anything to the contrary, the total amount of Development Costs that Grifols shall be required to pay for each calendar quarter shall not exceed one hundred and thirty percent (130%) of the Budget for such calendar quarter, without Grifols’ prior written consent. Without limiting the foregoing, Aradigm shall promptly notify Grifols and the JSC in the event that Development Costs are expected to exceed the Budget in any calendar quarter during the Term. Aradigm shall have the right to include any Development Costs in excess of such one hundred and thirty percent (130%), to the extent not previously reimbursed by Grifols, in the Development Costs invoiced during the next calendar quarter (subject, in all events, to the 130% limitation per quarter).

Notwithstanding anything to the contrary in a manner consistent this Agreement, in no event shall the total, aggregate Development Costs for which Grifols is liable under this Agreement with respect to the Budget) Aradigm Product for the prior Calendar Year Initial Indication exceed sixty-five million dollars (“Actual Annual Costs”) against that portion of the Cost Advance for such Third Party Costs for that Calendar Year, including reasonable documentation of such Actual Annual Costs. The form of such reconciliation shall be subject to JDC review and approval. If the amounts paid for anticipated Third Party Costs in the Cost Advance exceeds the Actual Annual Costs, then Paragon will credit such excess payment against Development Costs contemplated in the Budget and reasonably expected to be incurred by Paragon in the performance of the Research Program during any upcoming Calendar Year and Spyre will deduct such amount from its next quarterly Cost Advance. If the Cost Advance is less than the Actual Annual Costs, then Paragon will invoice Spyre for the difference and Spyre will pay such amount together with its next quarterly Cost Advance.
